3. When the Transfer Assembly lowers, the Transfer Roller retracts from the
Transfer Belt.

Transfer Roller Cleaning
DC positive and negative transfer bias voltages are alternately applied to the
Transfer Roller. These charges oppose those on the Transfer Belt attracting
toner residue on the Transfer Roller back to the Transfer Belt. The Transfer
Belt cleaning blade collects the waste toner from the belt and stores the waste
in the Imaging Unit.
Transfer Roller cleaning occurs when:
Power Switch is turned ON
Cover is opened and closed
A media error occurs during a print cycle.
A paper empty condition occurs during a print cycle.
A paper size error occurs during a print cycle.
For stable printing, the parameters related to forming both the electrostatic
and toner image are continuously monitored and adjusted by the printer.
Parameter correction and control over the entire printing process is called
"process control". Two primary process control mechanisms are used by the
system, Automatic Transfer Voltage Control (ATVC) and Automatic Image
Density Control (AIDC).
