I'm trying to repair a copier donated to a non-profit that was
said to be in good condition before being moved. I'm not a real
copier tech, although I know how they work having built
copiers and offset duplicators about 35 years ago at Addressograph-
Multigraph (now defunct). I tell you that so you won't think of me
as a total amateur. My background now is electronic instrumentation.
This copier works fine except for streaks and bands in the paper
feed direction. There is so much toner on the PC drum it almost
looks as if there had been a toner spill. I downloaded a service
manual and I'm not sure where to begin. Any tips appreciated.
I cleaned the corona units accessable from the front cover, but
nothing else. The mylar strip that can be seen from the underside
of the PC drum isn't touching..the description in manual sounds
as if it is always in contact with the surface, but that would require
processing the original for each copy. Is that correct?
Any help will be much appreciated; we don't have
the $$ to bring in a pro and it would be too bad to just dump this
machine.
