8.1 Cleaning

Excepting the Print Head, there is no parts or components that need to be cleaned on a
regular basis. Clean the printer as need arises. When cleaning, make sure to observe the
methods and cautions described below.

8.1.1 Cleaning Method

 Do not wipe transparent parts with a cloth moistened with
alcohol or diluted alcohol. Doing so may make the
transparent parts cloudy.
 When wiping paper dust off the LD Roller/Pickup Roller,
do not wipe against the grain of the roller surface.
EXTERIOR PARTS SUCH AS HOUSING
Wipe the surface using a soft clean cloth moistened with water. Use of an unwoven
cloth is recommended for coated or transparent part to prevent damaging the surface.
INSIDE THE PRINTER
Use a vacuum cleaner for removing paper dust.
RUBBER OR PLASTIC ROLLERS IN THE PAPER FEED
MECHANISM SUCH AS LD ROLLER/PICKUP ROLLER
If paper dust adhered to the roller surface drops the frictional force and causes paper
feed problems, moisten a cloth with water and wring the water out, then wipe the dust
off the roller using the cloth.
SCANNER GLASS
Wipe the scanner glass using a soft clean cloth.
When oil stain or stubborn stains are attached, clean with a small amount of glass
cleaner attached to a soft cloth.
