Maintenance and Transportation
Cleaning the printer
To keep your printer operating at its best, you should dean it
thoroughly several times a year.
1. Make Sure the printer is turned off. Then remove any paper
as well as the paper cassette and output guide. Also
remove the optional push tractor, if installed.
2.
Use a soft brush to carefully brush away all dust and dirt.
3. If the outer case or paper cassette is dirty or dusty, clean it
with a soft, clean cloth dampened with mild detergent.
Keep the printer cover in place to prevent water from
getting inside the printer.
Caution:
Never use alcohols or thinners to clean the printer; these
chemicals can damage the components as well as the case.
Do not use a hard or abrasive brush.
Do not spray the inside of the printer with lubricants;
unsuitable oils can damage the mechanism. Contact your
dealer or a qualified service person if you think lubrication
is needed.
Be careful not to get water on the printer mechanism or
electronic components.
