Transfer Roll Service Check
Service Tip: The transfer roll is 51.02 mm (2.009 inch) diameter. Any
print quality problems such as lines that are spaced 15.2 mm apart
indicate you should check the transfer roll for damage, toner or
foreign material buildup.
Service Tip: The transfer roll assembly is part of the Maintenance Kit

check the voltage at J10-12. It reads
approxi5 V dc with the
controller board removed from the
printer. If incorrect, replace the
engine board. If correct, replace the
toner sensor assembly. A bad
ground connection between J10-13
on the engine board and pin 3 on the
toner sensor results in a 929 service
error.
