Canon mp550 printer shows error code 200. Meaning and Debugging of Printer Error B200
Every owner of a Canon inkjet printer (regardless of its model) sooner or later encounters error B200, which occurs a little more often in devices that use a print head rather than cartridges. Below we will describe ways to solve this error, so that you can solve the problem yourself, without calling a technician to your home. But we ask you to be attentive and careful with technology. When this error occurs, the Canon manufacturer recommends turning off the device and contacting the nearest service center in your city. As you understand, it is beneficial for them, but not for us. And so let's understand this problem together.
We strongly ask you to read the article to the end. This error is not simple and requires testing. Therefore, take a piece of paper with a pen and write down our recommendations. You may forget to do something, and then you will have to go to the service center. At the bottom of this article there is a selection of videos that will allow you to clearly see how to solve this problem.
Attention! If your printer is under warranty, then do nothing, close this article or just read it if you are interested. If you start disassembling the device, your warranty will be voided and you will have to pay for repairs out of your wallet. Therefore, it is better to take the device to the store where you bought the printer and let them decide what to do with your device. Is your warranty already expired? Then let's start reading this article.
| Error b200 Canon |
The first possible solution to this situation is to simply remove the ink cartridges for a while. You need to take them out for about an hour, and you should also turn off the printer. Then you need to move the printer carriage to the center and turn it off.
When you unplug the printer and remove the cartridges, the printer will cool down a bit and it will be even better if you turn off the printer so that no electrical current continues to flow through it.
When this happens, there is a possibility of damaging the cartridges and burning out the printer circuits. Read Recommendations for caring for the electronic circuitry of ink cartridges. If you have any concerns regarding this topic, please contact us via a comment on this article.
If you carry out this procedure and put the cartridges back, but the problem is not resolved, carefully inspect the cartridge connectors and you will see that they are burnt out. . see image of cartridge connectors.
The second possible solution has to do with the print head and the carriage that moves the ink cartridges. We know that the printer carriage can sometimes pose a problem for it. The problem is that the PGs fill with ink, so it is recommended to clean the printer connectors. If you need help, just leave a comment on this article and we will be happy to answer you.
If not all users who use Canon MFPs in their daily work, then many of them often observe the appearance of a Canon B200 printer error. This code, of course, may indicate a physical problem (which, in fact, is what failures of this type are usually associated with). However, this is not always the case. The software part should not be discounted either. Canon B200 printer error may also appear due to incorrectly installed drivers and related software. This problem can be corrected in several ways, including physical intervention and software solutions. The first option should be used only if the native software tools installed when installing drivers do not work.
What does error B200 mean on a Canon printer?As a rule, everyone who encounters such a failure sees a message on the computer monitor screen indicating that a failure has occurred and printing is impossible.
The printer message (error code B200) can be issued in either Russian or English. Most often this is due to physical damage to the print head or unfilled cartridges.
The main misconceptionSome owners of this type of equipment believe that the printer fails (error B200) only because it itself has physical malfunctions, and they are deeply mistaken. Software should not be discounted either. At least that's what the drivers say.
First remedyIn the simplest case, a standard and universal solution to the problem can be used for all devices of a given manufacturer.
Suppose, when trying to print, a failure occurred with code B200 (a printer error occurred). The standard remedy for this situation, by the way, in relation to all printing devices, is clearing the print queue.
This is done quite simply if you go to the file section of the printer after calling the menu from the system tray. Here you can use the line to clear the print queue. True, this method does not always help. There may also be a situation where error B200 (the Canon MG5340 printer sometimes gives it) is observed even after this. In this case, even if the device is networked, you can simply restart the computer terminal. When restarting, printing starts automatically (provided the computer to which the device is directly connected is turned on).
Replacing cartridgesThe main problem with cartridges when a Canon B200 printer error appears may be due to the fact that it is not the original cartridge that is used, but a Chinese one.
As a result, the print head may overheat. It can simply burn (or melt). So you should take care of it in advance.
FlushingIf, after this, a notification is issued that a B200 failure has occurred (a Canon printer error has occurred), you should think about flushing.
This can be done quite simply, even without the use of specialized tools (you can use software controls that were installed during the driver installation process).
How to save the scanner?The fact that the printer is the first to suffer during such failures is not so bad. In fact, most Canon devices are MFPs with additional capabilities.
As a rule, the second most important thing is the scanner. But this is exactly what you can use, even if printing doesn’t work. You just need to cover some contacts on the board with electrical tape. It is not recommended to use clear or translucent tape as the diagnostic tool will determine the system to be inoperative (based on feedback from the contacts).
All contacts marked 2k and 5k need to be insulated. In the second case, you can use the 4k/5k scheme. At least, user reviews on the Internet indicate that such actions help in almost 99 percent of cases out of 100. But you will have to perform such operations, as they say, at your own peril and risk, since an incorrect action can lead to complete inoperability of the MFP . And then, as they say, there will be no sin.
Canon printer: error code B200. Driver installation issuesDevice drivers also play an important role. If Canon B200 printer error appears, sometimes the problem may be broken, missing or outdated device drivers.
The simplest method, it is believed, is to update the printer software from the standard “Device Manager” by selecting the appropriate item in the RMB menu or from the properties section.
However, drivers will be installed from Windows' own database, which does not always contribute to the correct operation of devices from this manufacturer. Therefore, when installing the appropriate software, it is better to use alternative sources: the disk supplied when purchasing the printer or downloaded drivers from the manufacturer’s website through a search indicating the DEV and VEN identifiers. In the equipment ID properties, you need to select the longest line.
On the official website of the manufacturer of this equipment you can find the latest versions of control software and drivers. If you don’t want to search manually, you can use automatic driver update utilities. Programs like Driver Booster, Slim Drivers, DriverPack Solution or something else like that are perfect. Such applications are capable of installing driver updates without much user intervention (only confirmation of installation is required after the search for updates is completed). True, the programs themselves with their updates will always be in startup, but you can disable them (the update will have to be done manually).
In Windows systems below the tenth version, for access, use the “Run” menu, where the msconfig command is written, and in Windows 10, startup elements can be disabled directly in the “Task Manager” (Win + R + taskmgr). You can also use the standard 3-finger combination (Ctrl + Alt + Del), which is probably familiar to any user who has encountered forced shutdown of frozen applications and programs. In any case, access can be achieved quite easily.
Is it possible to get rid of the B200 error at all?In principle, it is believed that you can get rid of this type of error even at the stage of its occurrence.
A very common opinion to correct the situation is to install a normal uninterruptible power supply. Failures with codes B200 or 400 can also appear due to a simple lack of voltage, not to mention exceeding the norm (which, unfortunately, is not uncommon in our country). When choosing a UPS, you need to start from the declared characteristics, because our 220 volts AC are completely incompatible with the 110 volts DC accepted in America or Europe as a standard for Western countries.
Among other things, you can use not only an uninterruptible power supply as an option. One of the most effective means is to install a voltage stabilizer. Jumps and fluctuations in our electrical network are not uncommon. And quite often a failure with message code B200 (“a Canon printer error has occurred”) can occur precisely for this reason.
Some conclusionsAs a result, we can say that the problem with Canon printers is quite common, and it is not always associated solely with physical damage to the devices themselves. Software components also play an important role. The same drivers or additional software, designed to ensure the correct operation of the device, are an integral part in the functioning of any type of equipment.
In general, if an error of this kind occurs on Canon printers, it is very bad. Actually, you will have to think about the issue of replacing equipment. At best, you can try to contact the nearest service center (this way you can, as they say, get away with little loss). On the other hand, if this is not possible, you can apply the troubleshooting methods described above, however, you will have to act at your own peril and risk.
However, to be completely sure, it is still better not to take risks and immediately contact some support center. It is believed that manual intervention in the operation of the device can only aggravate an already unpleasant situation. It is possible that the printer can then simply be thrown into a landfill. But the equipment itself is quite expensive. So, before making a decision about performing certain actions, think a hundred times, so that manual intervention or any other incorrect actions do not lead to an even greater destructive effect (and this can happen, but then you will have to reap the fruits of your own illegibility in the selected methods).
It can be very frustrating when you need to type something important and instead you see an error code pop up. One of the worst Canon printer errors is B200, which can indicate a potentially catastrophic device error.
However, don't go to extremes right away, printers are expensive and there are a few things you can do to try and fix the problem before you go out and buy a new printer.
What is the cause of the Canon B200 error?
At the most basic level, the B200 error indicates a faulty printhead. The print head is the part that actually distributes the ink from the cartridges onto the paper, which means it is one of the most important parts in the entire printer.
Printheads are known to be problematic, especially on cheaper printers, so the B200 error means that there is some problem with the printhead, which the printer reads as a catastrophic error.
How can I fix Canon B200 error?
There are several ways to fix a faulty print head. Try these fixes before you start replacing your entire device.
1. Reset the printer. Turn off the printer and leave it unplugged for at least 30 minutes. Sometimes a good reset can help as it allows the printer to cool down and return everything to the correct position when turned on.
2. Remove all obstacles. There is a chance that something is disrupting the connection to your print head. Open your printer door and the print head should slide out for you to access it. Carefully unplug it and remove it from the printer.
Note: There is usually a lever on the printer head that you push to remove it.
3. Clean the print head using your PC's maintenance options.
4. Manual cleaning of the print head. Use pure alcohol or oil-free cleaner to clean the gold contacts on the print head. Use a microfiber cloth to wipe the cleaner onto the contacts, then let it dry briefly to ensure it is completely dry before reconnecting.
Warning: Printheads are very fragile - handle them with care!
5. Remove old ink. Cured ink may have gotten inside the print head. Rinse them with distilled water until the water comes out clear. Wipe dry with a paper towel, then insert the head into the printer.
6. Reinstall your printer drivers. Find your device on the official Canon support page and follow the instructions to update the drivers.
7. Try a new ink cartridge. Faulty cartridges rarely cause this error, but it can happen. Refer to the user manual for this process regarding your specific device.
8. If none of the above methods work to fix error B200, it's probably time to go shopping for a new printer.
Note: Although it is possible to find the right part and install it, the cost of a new printhead will be about the same as buying a completely new printer.
Every owner of a Canon inkjet printer (regardless of its model) sooner or later encounters error B200, which occurs a little more often in devices that use a print head rather than cartridges. Below we will describe ways to solve this error, so that you can solve the problem yourself, without calling a technician to your home. But we ask you to be attentive and careful with technology.

Attention! If your printer is under warranty, then do nothing, close this article or just read it if you are interested. If you start disassembling the device, your warranty will be voided and you will have to pay for repairs out of your wallet. Therefore, it is better to take the device to the store where you bought the printer and let them decide what to do with your device. Is your warranty already expired? Then let's start reading this article.
When this error occurs, the following window appears in front of the user:
Also this error may be in English:
Of course, you must understand that language has no effect on solving a problem. Now let's start solving this issue.
This error can also be seen on the printer displays:
When this error appears, the printer behaves unusually - the indicators on the device panel flash alternately yellow and green. In this way, Canon makes it clear to the user that there are problems with your device - error B200. This error is also called “VH monitor error” - there is a problem with the print head power supply or it is possible that some cartridge is not working. In other words, this is a kind of signal that there is a problem in the print head or one of the cartridges. In addition, when this error appears, it may be a signal that the power supply is broken, but the latter problem does not occur often, and we can say for sure that if this is the problem, then you are lucky.
Canon devices may notice that you installed a non-original cartridge and therefore you receive error B 200. If you recently bought a cartridge or if you knew that it was Chinese, then it makes sense to try inserting the original cartridge and see how the device reacts.
It should also not be ruled out that even if the cartridge is at fault and you replaced it, then your head may fail, which overheated while using a non-original cartridge and, as a result, burned out. After replacing the cartridge, you may be lucky and the error will disappear. It remains to check this.
If you have empty cartridges, you definitely need to refill them!
Another very important point is cartridges. If your device has 2 cartridges, then remove them from the printer and insert them into the device one by one. If you get an error when connecting one of the cartridges, it means one of them is faulty.
A quick way to solve the problemThis method is not suitable for all Canon printers and MFPs. After reviewing these instructions, you will understand whether this method can be performed on your device. Now watch the video for ordinary users who do not have special devices:
Unfortunately, these videos are in English. But in any case, the video shows what needs to be done.
Initial diagnosisFirst, you need to diagnose your printer in order to know for sure what is wrong with it. A problem with the power supply is often determined by visual inspection. The capacitors on a failed power supply will be swollen. Just in case (if everything is visually normal with the unit), you can also measure its voltage at the control board connector.
At the time the printer starts (when you press the power button), the voltage reading should be in the range of 0.5 s with data of 24-32 V, which is quite normal for this device. Another way to test a power supply is to connect it to a guaranteed working Canon printer. But here you should be careful. Under no circumstances should you connect a working unit to a printer with a broken B200, since if the print head or control board in it burns out, the new power supply will suffer the same fate. In order not to break 2 devices at once, we ask you not to do this.
If, when checking the unit, no breakdown is revealed, then you need to remove the print head from the printer and look at the monitor. Is error B200 still occurring? This means there is a malfunction in the control board and not very good news - perhaps your controller with the print head has also burned out. The saddest thing is that if you buy these devices, the amount will be equal to the cost of a new Canon printer or MFP, which means a trip to the store to buy a printer is inevitable.
It’s another matter if, after you removed the print head, the error disappeared, and a new message on the monitor informs you that the printer is missing a head that must be installed for its further operation. This means that the control board is most likely (not 100%, but still) working properly and the problem is solely in the print head.
If such an error appears in the MFP, is it possible to “save” at least the scanner?In Canon devices, in case of error B200, you can do the following - you need to cover all the contacts of the PG (see the figure below) with electrical tape (but just do not use transparent tape for this purpose), after which the controller will not receive signals about sensor failure and it will start reading the print head serviceable. This will save you from error B200 and allow you to use the scanner (since the print head is not needed when scanning).
The trick here is that if at least one sensor fails, the Canon controller will perceive the entire system as faulty. By sealing the contacts with insulating tape, we get the opportunity to use at least a scanner. In the picture below we showed how many contacts need to be covered with electrical tape and also wrote how many contacts are in the shaded area. You need to glue it as in the picture:
Once your contacts have been sealed, you can carefully remove the pieces of electrical tape, releasing one of the contacts at a time, and install the head into the device each time. If an error occurs, return the electrical tape to the contact that was just peeled off and continue the same manipulations with other contacts. So we will ultimately come to a situation where only non-working contacts will be sealed, while working cartridges will print.
Having completed the manipulations described below, the device will stop showing error B200 after a couple of days, and maybe after 15 minutes. It is worth noting that when using this option, the device can work from 2 weeks to 1 year.
Below are pictures that show which contacts you can try to seal.
1.If you cover these contacts with electrical tape, you can print with a black cartridge:
2.If the device works with this option, then you will be able to print only with color cartridges:
3.In this case, you can print in black and color:
4.And the last option – black and colored:
Note: There is a video below that shows how this is done.
Is it possible to avoid error B200?There is an opinion that failure of the controller, PG or PSU occurs due to surges in the power supply, therefore it is highly recommended to use a UPS (uninterruptible power supply), which has a voltage regulation function. In addition, the following can often lead to an error: refilling cartridges with ink of questionable quality, installing a PG that has not yet dried after washing, and printing with empty cartridges.
It is worth noting that in branded cartridges it is difficult to keep track of the ink levels, because... they are made of opaque plastic (for this reason, you should not disable the ink level control function). You can, of course, install a continuous ink supply system, but not all users agree to this procedure.
Let's sum it upIf the solution options described here did not help you, then you should think about looking for a service center that can help you. Even if they don’t help, they will tell you what the reason is, and you will start from this figure - make a device or buy a new one.
Finally, let’s say that if you have a B200 error, then this is very, very bad, since most often the repair will be extremely costly and will not always be effective. Before you go to the store, don't panic and try the tips and tricks above. It is quite possible that your problem will be solved with “little loss.” Good luck to you!
If you encounter such an error, then we ask you to write a comment at the bottom of the article with the following information: printer model, how long you have been using the printer and after which the error appeared.
To replace the head, opened the lid and turned on. nutrition.
Instead of immediately writing B200, the printer began to show signs of loading (buzzing, turning the pump, etc.) and after a while it wrote “Close the lid.”
I closed the lid and the working screen appeared as usual.
I had it cleaned and tested the nozzles - the result was perfect.
It worked for about a week and the next time I turned it on it wrote B200 again. The trick with the lid didn't work anymore. Although when the lid was open, it also loaded and asked to close the lid. After closing, the working screen appeared and after 2-3 seconds. B200. There are no solutions to this problem on the Russian Internet (except for sealing the contacts with electrical tape). I decided to look in English.
I found a very interesting topic on the American Canon forum:
http://community.usa...r-b200/td-p/217
There people with various dances and tambourines eliminate the B200 error. Many people write that one method or another helped. This is what helped me personally this time:
1. Turn off power and leave plugged in.
2. Open lid and slide ink tray to the far left.
3. Press power button 5 times.
4. Close the lid and let the machine reboot.
How I understood and did it:
1 - After B200 I turned off the MFP
Before this, the tasks on my computer included cleaning the head and printing a nozzle check page (left over from previous experiments). After closing the lid and loading the MFP, head cleaning began and a test page printed. After this, the printer started working and began printing.
Turned it on/off several times - the flight was normal.
Nozzle check scan:
And that is not all!
I took out the old head, which also once stopped working on the B200, and did the same manipulation. And, lo and behold! She also made money. After two years, of course, it has dried out and does not print, but it can be detected, it can see the ink tanks, and it shows the ink level. I'll try to soak it.
Try, experiment, write to whom what actions from the American forum helped and on what models!
The result, of course, is not great, but the fact that there is no more error, the head is working and printing, is important. I'll try to soak it some more. In a pinch, it will do as a spare for a rainy day.
But the most important question is different.
For several years now, they have been writing everywhere that the B200 is scary, it means that the nozzles and taps on the head are burnt out. That the head is 100% replaceable, better yet together with some kind of board. But in fact it turns out that after resetting this error, the head prints as before.
Scanning and copying other originals is no problem.
SCORPIC, I have all my equipment through a good UPS.
It turns out that the B200 is not 100% a hardware problem in the head. As I understand it, under a certain set of circumstances (low voltage, overheating, temporary incomprehensible glitch, and who knows what else) an error is programmed into the head. And from that moment on, other printers also begin to recognize it as non-working (I tried to move it to my second MFP). Those. the printer no longer tests the head for functionality, but simply reads the error code from it and says that it is not working.
After performing the manipulations that are described at the beginning of the topic, this error code is erased from your head. When turned on, the printer carries out all the necessary checks, does not detect problems or damage and allows this head to continue working.
Personally, this is exactly how I see this situation.

It would be brilliant if this were really true.

The second one, which lay there for two years, had stripes, of course.
The blockage is obvious. The head must be carefully dug out and restored. This blockage is causing overheating.

Futureworld, You jump from one topic to another and collect them in one pile. If you carefully read my messages in both topics, you probably noticed that I have two similar MFPs - MP630 and MP640. In the thread where we were talking about buying a head from China, the conversation was about the MP640. He is staying with his wife's parents. Now it has a head from China, the link to which I gave you in the same topic. Prints without any problems. I did not post scans of tests of the new head from China as it was unnecessary neither here nor in that topic. Unfortunately, they threw away the old head, so it won’t be possible to experiment with it in the same way.
In this topic we are talking only about the MP630, which has been working at my home since 2009. I took the last scans and photos only to show that the scanner in tests sees non-existent rainbow stains, which do not exist if the same sheets are taken with a camera.
For this printer I now have two heads:
1 - worked for the last 2 years, the other day I showed B200, I “reset” it and now I’m working with it further (the very first scan in this topic, as well as a scan from the service mode (right) in my last message. In the photo it’s the same left). I didn't do any leveling.
2 - stood BEFORE this, showed B200 and lay around with dried ink for 2 years. I also cleared the error, soaked it for several hours and tried to print. The result is in my second message. The same test in the previous message is the left scan and in the photo on the right. And about which
SCORPIC said:
Considering that the head lay like a corpse for 2 years, the result is superb!
SCORPIC said:
I don't claim that this is 100% true. Just a possible explanation why the error disappears after such manipulations. It's not just me. Americans also unsubscribe, which helps.
It can also be assumed that these actions do not reset the error itself, but force the printer to test its head. And if no problems are found, then it writes something like error0 or TestOK into it
In general, someone else needs to experiment and report the results.
Sunny dog
Thanks for the clarifications. I would be very grateful if you print and take a photo of the nozzle test from the 640 that has a new head from China (topic: MP640 blue color disappears on the new head). Did you wash it of preservatives before installing it?
On this topic, I can say that it seems to me that the nozzle tests on both heads for the 630 are not ideal, but the first one is better. Which seems to suggest that even if we managed to deceive the printer now, then soon any head may fail, because it has some problems. Only time will tell here.
Also, it seems like they always recommend doing alignment after manipulating the head.
Sunny dog, error B200 was resolved using your method on 5 client devices that overheated their heads. On Canon PIXMA PRO-100 the problem is also fixed. So the topic needs to be pinned as Solved. Learn little ones! Topicstarter is a big plus!
Get rid of the b200, give Canon to the masses!

ps/ I think the yellow blacks from Canon read this forum, so they can soon eliminate this bug.

And they said that they were breaking through the transistors on the board...
Again, it is not clear how these manipulations eliminate this bug. Most likely the error sensors are reset or all are reset. Alternatively, the head of one of the GHG sensors falls off. Pun Again, a crutch - i.e. eliminating not the cause of the disease, but only the symptom.
Oddly enough, I encountered a similar thing on Kuosera lasers, when the toner concentration sensor of the development unit fell off when mixing non-original toners and, when the development unit was working, it wrote - Replace the development unit.

I got B203 on my MG5640. Moreover, at first I somehow dripped my head, stood for a day and the error disappeared. Worked for a while.
Then it came out again, cleaning and washing didn’t help. Well, I put it on the shelf for a month or two. Then I accidentally came across this topic from ixbt.
But this helped:
1 - After B200 I turned off the MFP
2 - Opened the lid, moved the carriage as far as possible to the left
Pressed the on button 3 - 5 times. (without waiting for complete switching on/off)
4 - After the last press, closed the lid.
Only point 4 did not help. It worked like this: the carriage went to the right and immediately went slightly to the left for cleaning, at that moment I closed it and the error did not come out.
I printed 16 A4 pages of children's cards. Approximately 30-40% page coverage.
And the devil pulled me to fill it with ink; according to the sensors, in some places it was already close to zero and some asked to be replaced.
In general, the black disappeared completely from the photo. If you apply it to the head, it goes away easily.
I took a starter cartridge, left it lying around for about 2 years, and dripped some ink onto a sponge. It doesn't print either. An exclamation mark appeared on his sensor.
I took my head apart. And the dist blew with a syringe. water into the channel onto the black nozzles. It came out of the nozzles crookedly somewhere mostly in the center. After 3 syringes of 10 ml each, the shower became normal. Put it back together. But still the black one does not want to print.
Futureworld, whether the error will return or not depends on the reasons for its initial appearance and the actual state of the head. If she is half dead, then of course she will come back. Using my own example, I can say this:
The head that has been lying there for two years with dry ink (which I wrote about at the very beginning) prints and so far does not produce any more B200. But the other head seems to have depressurized and ink is getting into it somewhere. If you wash it and dry it on the battery for a day, it prints perfectly. But it sits in the printer for a couple of days and the B200 is back. Moreover, resetting the error is enough for one turn on. When I try to print something it appears again. After digging and drying it works again. I sent 150 pages with pictures - it prints perfectly. But after 2-3 days again B200. In general, for now I once again dripped it and dried it. I think it is quite possible to use it for printing large one-time volumes.
I got this error several times on my PIXMA MX924. The first time I ignored (postponed for later) the indication that the ink in the yellow cartridge was low. After that, as a result of turning it off and on after some time, the printer itself restored its functionality, printed several pages and again went into error. At the same time, the print quality was excellent. Up to this point I have only used originals. I read a bunch of tips on resetting error B200, the advice with moving the carriage to the left all the way and pressing the ON button five times helped. After that, I reset the error a couple of times by pressing the ON button five times in the off state without retracting the head. Those. an error occurred, the printer was turned off with the ON button, rested in this state for 20 minutes, then the ON button was pressed 5 times at half-second intervals, the printer turned on, buzzed longer than usual and went into operating mode. When the original ink ran out, I decided to refill the original cartridges with Canon GI-490 ink, and took the black photo from OCP (CANON does not have them). The technology for refilling originals with removing the balls is well described on the website, I will not repeat it. The only thing I did was cut off the original chips and glued on the Chinese ones with auto reset. These chips turned out to be thicker; the cartridges fit into the carriage tightly and with a slight distortion. Perhaps because of this, the black pigment began to leak a little (traces of ink are clearly visible on the foam tape over which the head moves). And somehow, when printing, the printer went into state B200 again. I removed the cartridges and the head - it was all filled with black ink. I wiped the head with a napkin soaked in OCP RSL service fluid, blew out the contacts and cable with a blower and put it in place. I refilled old original cartridges with original chips by injection into the adsorber without depressurization. Each cartridge took about 6-8 ml. I put the cartridges in place, reset the ink level control, cleaned it, printed a test - everything works. And there are no traces of ink on the foam rubber (I first removed it, washed it and put it back). The printer worked honestly for a week, but my inquisitive mind does not give my hands a rest :-) Yesterday I decided to put back the refilled original cartridges with re-glued chips to control the ink levels. To do this, I removed the cartridges, the head (it was clean), removed the gaskets on the ink intakes, installed additional silicone gaskets (they were supposed to level out the slight misalignment of the cartridges by changing the thickness of the chips and corresponded in thickness to the chips), installed the original gaskets on top, and put the cartridges in place , did a couple of cleanings, achieving the perfect test, automatic alignment of the heads, printed a photo. The test and photos on photo paper turned out great. On a regular photo in standard quality, stripes are noticeable. This morning I ran a nozzle test - everything was fine. But I again noticed traces of black ink on the foam rubber. I will observe the behavior of the printer, if the problem recurs, I will replace the pigment cartridge. What is important here is the fact that error B200 occurred due to problems with ink supply and the ability to reset it and allow the printer to operate normally.
There was also error B200, after such manipulations my canon ip7240 went into ready mode, but after sending it for printing it turned off and does not turn on at all.
