Theory of Operation
Transfer Roller Retraction
To retract the Transfer Roller from the Transfer Belt, the system performs the
following steps:
1. When the Image Transfer Solenoid is energized, the Transfer Roller is presses
against the Transfer Belt and the Transfer Roller Clutch rotates a half turn. This
moves the Pressure Slider.
2. When the Pressure Slider moves, the Transfer Assembly, which has been
pushed up by the ribs on the Pressure Slider, lowers.
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.
