Today ordered 8 piece of registration roller bushings and registration clutch,they usually wear out at 500-700k.
I have one piece of this machine at 1.500.000 clicks and just now its showing this problem with bushings,
One of the rare "weak" points on this machines if it could be called weak point at so many prints
That's what I was thinking the sticking solenoid would cause overtoning. I just remembering when i was servicing a lot of the Biz 200/250/350 many of them would run light. Seems like we were changing drums & developers around 30-40k halfway through their life. Been awhile but might have been aftermarket drums & OEM developer.
The transfer contact on these caused light printing.
Always tweaked the machines to use less toner for cost saving
30 years for the spirit of the Di250 to die...

Whatever
Scanning on the 350 is a challenge. Ftp is all I can use. Forget about scan to email.
