https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MX922-Printer-with-B200-error-code/m-p/443568#M67209 <P>My 8 year old Mx922 which hadn't been used for some time could not clear the blocked jets on the print head with the maintenance option so I decided to get the print head out and cleaned up with cleaning fluid and a hypodermic syringe. Luckily a you tube video showed my how to remove it as its a bit tricky and I squirted cleaning fluid through the 5 entry entry points (where the cartridges fit). Once cleaned I replaced the print head and fitted new ink jet cartridges. On power on I got the B2000 error code that many others have reported issues with.</P><P>I ran through many of the 'cures' to fix it from cleaning the print head contacts and the printers pins that push against the head, I tried powering off and unplugging many times and re-seating the new ink cartridges and trying different power on cycles but none fixed it. Finally I noticed two pins on the cartridge had ink on them and cleaned them up. Still no joy despite repeating some of the 'tricks' suggested but to no avail. Finally I gave up to watch a movie and have a meal and when I tried one more time afterwards It carried out a nozzle cleaning without any error and then printed a page OK.&nbsp; Go figure, I can't say exactly what I did to fix it but hopefully it will remain working..</P> Mon, 30 Oct 2023 02:43:29 GMT Expat-Mike 2023-10-30T02:43:29Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MX922-Printer-with-B200-error-code/m-p/443568#M67209 <P>My 8 year old Mx922 which hadn't been used for some time could not clear the blocked jets on the print head with the maintenance option so I decided to get the print head out and cleaned up with cleaning fluid and a hypodermic syringe.
