Ricoh MP6002 - sc320-01

[daveh12]

Hi all,
Any help with this issue is greatly appreciated. The above machine constantly codes out to the code listed. Recycling the power clears the error until you run another job and after the last sheet it codes to sc320-01 within 3 seconds.
Firmware is the latest, have replaced Dev power pack, and Dev unit. Worked fine for 2 days then back to square one. There was a similar thread on this posted a few years back where the electrode copper connections were replaced at the rear of the machine and this fixed that problem however no such luck for me after I replaced them
Checked with ricoh support and as of yet have no suggestions.
And help please would be great.

Have you replaced the black plastic "bracket" pn B065-1137 which houses the drum shaft support bearing?

Development output abnormal
The high voltage applied to the development unit is detected 10 to be times higher than the upper limit (45%) of PWM.
-
 Development power pack defective
 Development bias leak due to poor connection, defective connector

Check all connectors to the HV power pack.

Apologies for the slow reply. One of those weeks. Yes this was replaced with both copper connectors but the issue remained.

Connections are solid and copper connectors were replaced. No change.
