Cleaning and Maintenance
Cleaning the printer
Automatic cleaning procedures to cure many problems are available through the
front panel by pressing the
Clean
button. Front panel messages guide you
through the necessary steps to perform cleaning procedures.
Cleaning supplies
A new printer includes these cleaning supplies:
■
Cleaning tray for cleaning pick rollers
■
Foam swabs
■
Cleaning cards
■
Lint-free wipes (dry)
■
Plastic bottle for dispensing isopropyl alcohol
■
Feed roller cleaning tool
Some cleaning procedures require using cloth wipes or swabs saturated with
isopropyl alcohol. Since shipping regulations prohibit supplying alcohol or
presoaked cleaning materials with the printer, you must supply 90% pure
isopropyl alcohol (available at pharmacies).
Using isopropyl alcohol
In general, it is best to use the purest isopropyl alcohol (99%) available. You can
use 90% pure isopropyl alcohol, but if you do, you must wait after cleaning to
make sure that printer parts are completely dry. 99% isopropyl alcohol dries
quickly; 90% isopropyl alcohol may take several minutes to dry.
Caution Do not use rubbing alcohol because it can contain water and oils
that leave undesirable residue on the printer parts. Never use
water to clean the printer’s internal components. Failure to follow
these instructions may invalidate the printer’s warranty.
Whenever the cleaning instructions refer to a lint-free cloth moistened with
isopropyl alcohol , you can substitute a pre-soaked alcohol cloth . When the cleaning
instructions direct you to use an alcohol-soaked swab, you can use the extra
alcohol in a pre-soaked alcohol cloth packet to moisten the swab.
Warning Alcohol is flammable; keep alcohol-soaked cloths and swabs away
from hot surfaces.
The reorder cleaning kit (order number 016-1520-00) includes pre-soaked
alcohol cloth packets.
