(3) Paper feed unit
To avoid print quality problems due to paper dust and debris, clean the paper feed unit in the
following manner:
Pull the paper feed unit release lever 1 up and draw the paper feed unit all the way out until it
stops. Wipe the paper dust on the upper registration roller 2 and the paper ramp 3 using the
wiper cloth 4 included in the toner kit.
CAUTION Do not touch the transfer roller 5 (black sponge roller) when wiping the paper
ramp 3.
Area 6 below is factory-applied with lubricating oil. When cleaning the paper
feed unit 7, do not use alcohol to clean this area. If the oil is completely removed,
an incorrect action of the MP tray paper sensor (8, actuator) will result.
