MF743Cdw stuck on Performing auto clean fixing assembly" and will not print

[david07666]

My MF743Cdw suddenly stopped printing.  The message at the bottom of the display says:

"Performing auto clean fixing assembly" and it just keeps saying this - it doesn't go away and it doesn't complete.

When I send something to the printer it shows up in the status queue on the remote UI as "Waiting" but never prints

The printer is a few months old and has printed almost 3,000 pages already.

I did put non-canon cartridges in it a few weeks ago but it's print printing just fine since then and the "Canon Genuine Mode" is Off.

I couldn't even shut it down by pressing the power button - I had to unplug it.  But when I plugged it back in I was in the same situation.

Any thoughts?

Thank you. After turning off Auto Clean Fixing Assemby I was able to print a test page. Harvey

David,

Thank you for posting this. I tried everything you had tried prior to seeing this post.  This worked immediately.  It is screaming of a SW bug in the system.  However, now I am good and able to use the printer completely.

Thank you!!! This worked for me after trying everything else for hours, this simple fix worked within seconds. I signed up just to give your answer a thumbs up to push it up the list to hopefully help others with the same issue.

This worked! Thank you!

And thank you to Canon for establishing and maintaining community website - since user manuals are useless.

Copy and cancel worked for me too.  Brilliant workaround!

To force the printer to power down, hold the power button down for about 10 seconds and it will exit and shut down.
