Cleaning The Bottom Plate
If the printed paper is smudged, the inside of the machine may be dirty. Periodic cleaning of
certain parts on the inside of your machine is recommended to maintain a high standard of
printing quality.
The parts can be cleaned in the following ways:
See "Cleaning The Bottom Plate" on page 96.
See "Cleaning The Protrusions Inside The Machine" on page 97.

Ensure that the machine is turned ON and there is no paper loaded in the Auto
Sheet Feeder.
2
Take a sheet of A4- or Letter- sized plain paper and fold it in half widthwise. Then,
open the paper.
3
Load it into the Auto Sheet Feeder with the opened side facing up.
