4.1.2 Cleaning the Exterior Parts/inside of the printer
This section describes how to clean the sections other than the carriage.
 Instructions for cleaning

Exterior parts such as housing
Wipe dirt off with a soft clean cloth moistened with water. For glossy or transparent parts, use of unwoven cloth is
recommended to avoid scratching those parts.
 Inside of the printer
Remove paper dust with a vacuum cleaner.
 Rubber or plastic rollers such as an Pickup Roller used to feed paper
If paper dust adhered to the rollers decreases the frictional force of the rollers and the rollers cannot properly feed
paper, wipe off the paper dust with a soft cloth moistened with diluted alcohol.
 Instructions for cleaning ink stains
Wipe the stains off with a cloth wrung out of diluted alcohol.
 Do not use alcohol for cleaning the transparent parts. Doing so may cause them to get
cloudy.
 When wiping paper dust off the Pickup Roller/Middle Roller, be careful not to rub
against the surface asperity.
 To minimize the effect on the parts, use diluted alcohol such as 70% diluted ether.
 After using alcohol for cleaning, make sure to wipe the part off with a soft dry dust-free
cloth to remove alcohol traces fully.
