[Misc] WC4250 - Light Image problem

[kurtray]

Customer has a WC4250 *just* out of warranty (of course), and they've had a creeping problem with images getting lighter.
Ran through the IQ7 Light Image RAP:
- Happens with both copies and prints, so it's not CCD
- Verified toner and drum don't have any extraneous packaging material
- Cleaned LSU window, but it was pretty clean to start with

No real difference in output as a result.

From here, it looks like it gets expensive: replace LSU, replace HVPS, replace side cover assembly, replace ambient temperature sensor, etc...

Looking for suggestions to nail down source of problem without buying a bunch of expensive parts to test it out!

Thanks,
Kurt

The problem may be in Drum Cartidge, Transfer roll (BTR) or Main PWB. Try also with Firmware Updete using CentreWare Internet Services (CWIS). Default Name is "admin", default password is "1111".

The problem was indeed resolved with a new drum cartridge.
Thanks!
