I know this is an older machine but the owner insists on it being fixed. We just put in a fuser for jamming. That worked out, though the machine fuser drive gear is worn & was making noise until I put on the old main fuser gear on the new one to make it quiet. Now debating if I should order a fuser drive assy. for that.
It also seems like it might have a boot loop problem. The customer mentioned something that sounded suspicious, but it kept coming up every time I turned it on until now. Can that be an intermittent problem ? I got it past that and came to ready again. I updated the firmware successfully. Might that be the problem ? Time will tell at this point.
