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