A few questions: 🙂
Do any of the other maintenance options start properly, or are they all impacted? Is there enough toner available to run the program? If the unit is unplugged for a minute or so, then plugged back in, does that make any difference? If the unit can be defaulted to factory settings, can that be tried to see if it makes a difference? 🤔
We've had this issue for over a year. Nothing works to resolve the error. I can't find anywhere that this part can be replaced like on other laser printers, either. It is very frustrating. The unit works great otherwise even though it is a few years old; we have over 168,000 prints on the unit.
We can print the "cleaning sheet" but then the program won't run when reloading the paper to continue.
The pages I posted are printouts. The cleaning process the OP refers to requires the paper to be in the tray after it prints a cleaning pattern. I suspect our fixer is broken since it isn't setting the toner correctly to the paper. But we can't clean it so I can't confirm.
