Transfer Roller Cleaning; Cleaning [All Models] - Ricoh G112 Service Manual

Transfer Roller Cleaning

After a paper jam or when the user sets the incorrect paper size, toner can transfer
to the rear side of printouts. To prevent this, the machine automatically cleans the
transfer roller before the next printing cycle.
During transfer roller cleaning, the high voltage supply applies a negative current
(–3µA) to the transfer roller.
The machine cleans the transfer roller in these conditions:
• At power on
• During fusing unit warm-up
• Immediately after a jam is removed
• When the front cover is opened and closed
• After a job which is 10 pages or larger
