Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Does the smear happen when copying or printing or both?
Could you attach a scanned image of a page with the smear?
I haven't heard back from you yet - please reply and let me know if you still need assistance with this.
Ahh ok, the "CLEANING FAILED" error can be caused by two things:
Cause 1: A paper jam occurred in the machine while the fixing unit is being cleaned.
Action: Clear the jammed paper, and then load paper again. Check for any stuck pieces of paper, staples, paperclips, etc.
Cause 2: The toner ran out completely while the fixing unit was being cleaned.
Action: Replace the toner cartridge with a new one.
