Confirmation Tasks
Is a heavy load imposed on the ID unit, for example, because
the waste toner belt was ruptured?
Use the SWITCH SCAN function of the self-diagnostic mode to
check to see if each ID motor operates normally.
Make this checking in the presence and absence of a load.
Confirmation Tasks
Check for any incomplete insertion or skew insertion of the
SSNS connector of the PU PCB (PRX) and the SSNS connector
of the toner sensor PCB (PRZ PCB). Also check to see if the
FFC has any wire breakage of peel-off of the covering.
After checking the connections, turn on the power again, and
see if the error is issued again.
