Clean or replace ALL OZONE filters periodically.

Check drum heater
Check transport duct for damage.

Check transport fan duct seal.
If damaged, replace immediately to maintain proper air flow and operation of machine.Not all foam seals are available in the parts catalog. Foam weather stripping from a hardware store may be used as a substitute.

**Knowledge is time consuming, exhausting and costly for a trained Tech.**
After replacing the Wires (and yes, sometimes you need to replace the grid wires too) did you reset the counters in service mode? If you forget this, the controller thinks: "hey, these wires are really old, i will give them an extra boost" and fires with all his might, this results in extremly cases in arcing on the drum surface and so in spots on the printouts.
If sometimes you feel a little useless, offended and depressed always remember that you were once the fastest and most victorious sperm of hundreds of millions!
Probably spilling from pre-transfer assembly or cleaner. Are they in a pattern or random?
