7655 System Fault

[denden4h]

I hope someone can give me some answers to this one. Customer says unit is displaying "System Fault, call service administrator", I go into UI Diagnostics (No PWS for this one) and the history says it has 2 codes: 22-720-000 and 42-326-000. I do have a service manual for a similar unit and was able to look up the second code, but not the first. The history says it is a service registry data load error, so I believe that the system software is corrupt. If anyone has any info on this, it is appreciated.

The transfer belt home position sensor is dirty or the patch on the belt is dirty. You will have to remove the transfer belt to clean the sensor.

the patch maybe dirty or ripped or sensor dirty

If the silver patch is riped
and the IBT is still in good shape grab a silver piece of the bag that the IBT came from cut out the same size square apply a double sided sticky tape to it then reapply to the belt should get you moving for a while intill your part comes in
