[Error Code] Konica 7155 sservice code 77-01

[rocky_biskit]

Hey all!
Ive got a k 7155 with an intermittent SC 77 01.
It codes more than not ... Any one know possible causes, and where I should begin looking? Also is there a maintenance reset for the code? It seems pwr off and on does reset it, but it ultimately will return after 2 or three copies.

Thanks all in advance.
