Canon Pixma IP8720 suddenly stopped working 5100 Error

[art021]

I purchased this printer in 2019. Everything worked fine. I printed yesterday with no issues, and I am suddenly getting a 5100 ERROR today. I upgraded my MAC OS operating systems recently but everything worked after the updates. There were no issues that would suggest this printer is at its end of life. I read about an upgrade program. Why is there no online form to submit for the upgrade program? Reading similar posts, a 19.99 support call gives no solution to a problem and the Canon online FAQ, Knowledge base, etc are about clicking links that lead you to no real solutions to a problem. Does anyone have a similar issue or an answer? Is there another brand that you would recommend?

Hi art021,

The 5100 can be caused by a paper jam.  Please use the links below to clear possible paper jams:

The 5100 error can also be caused when the encoder/timing strip inside your PIXMA iP8720 is smudged.

To clean the encoder/timing strip, please follow the steps in this Knowledgebase Article:
