Transfer Roll Service Check
Service Tip: The transfer roll is 51.02 mm (2.009 inch)
circumference. Any print quality problems such as lines that are
spaced 51.02 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
and is replaced when a '80 Scheduled Maintenance” message
displays. Ask the customer if they have replaced the transfer roll
recently.
CAUTION: Make sure the printer is powered off before making any
checks on the transfer roll or associated parts for personal safety
and to prevent damage to the printer.
