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!!! 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!

I have tried all the prior solutions.  I replaced the starter cartridges with new ones, reloaded the paper, and restarted the machine.  How can I turn off the Auto Clean Fixing Assembly option, so it doesn't do this automatically?  Also, is there a way to stop the warnings for non Canon cartridges everytime it starts?

[david07666]

There is no way to stop the warnings about non-Canon toner.

To turn off auto clean:

<Menu>
<Adjustment/Maintenance>
<Adjust Image Quality>
<Special Processing>
<AutoClean Fixing Assembly>    NOTE: you might have to scroll up to find this 
<Off> 

and then I think it asks you to save and you select <Yes>

I have the same problem as noted above. It is a serious problem that Canon appears to intentionally sabatoge the use of 3rd party cartriges. Maybe Canpn should more reasonbly price their cartriges. Be that as it may, How do you turn off the auto clean fixing assembly" function. Thank you.

Same issue with an MFP743 ... none of the solutions presented has worked so far...

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