MG7720: Error B203 Suddenly occurs, on MULTIPLE printers in different locations

TerriLLBean — Tue, 27 Apr 2021 20:31:45 GMT

Yesterday, I spent the afternoon helping a friend troubleshoot a B203 error on her Canon MG7720 (Which I recommended she purchase a while back). She was printing key papers and encountered this error. After hours on the phone with Canon support, she finally just purchased a new printer.

HOWEVER, this morning, I went to print something on MY Canon MG7720 printer, and suddenly a B203 error appeared! There is no way our printers would simultaneously have errors requiring a repair. As a software engineer who spends time debugging, this sounds to me like a bad device driver or firmware update when the printer searches to update.

Has anyone else encountered a B203 error recently (and suddenly) on their printer? Suggestions for how to possibly update the firmware, when the printer goes into a B203 and won't update. Other suggestions are appreciated.

I am hoping for suggestions from anyone in the community. Printing is of utmost importance to me.

Thank you for your response and the Links. I am also pursuing support (although they simply try to sell you a new printer 🙂 ). But I did not know about the knowledgebase. Thank you for that. I'm searching for that error

Hi TerriLLBean,

Please check for paper jams:

Next, please reseat the ink tanks and printhead:

I've looked at all the obvious suggestions. There's no jams, or problems with the internet. I've also tried reseating the printer ink and print head.

NOTE- this is happening with the same error on two different MG7720 printers in 2 different locations. So I'm also looking to verify that there was not a firmware update. This smells of a firmware issue and not a random "we both just happened to have problems with our print heads at the same time".

I've found a few suggestions on the internet for cleaning the print head. I will try that this evening. And work with support after that. The "ok, just buy a new Canon" approach is a bit worrisome, since Canons appear to break down with little that you can do.

Thank you to date, for your suggestions and I'll update this post once I try a few things with the print head.

Update. I have cleaned the print head and reseated it. Still receiving an error B203
