I,m getting blank copies occasionally, well mostly blank ... it looks mostly like the transfer potential is really low because I get a partial transfer - then towards the end of the copy I get background and light transfer ???

The copier was freshly P.M.'ed with the full kit and developer 10-15,000 copies ago ... I've checked everything !!

I even tried toning it up a bit, it was after this that the machine just all-of-a-sudden starting working again ... and the copy quality is outstanding ???

If the tranfer corona was arcing would it throw a code 28 ??? like most other konica's

Any Ideas ???,,, Thanks, Mike

Could be Charge corona
Transfer corona
Dev tank
Or poor drum unit contact

Possibly front door switch.
I've seen the switch cause the entire page be almost blank with background

Replace the front door interlock switch. Problem solved.
