Routine Care and
Troubleshooting
Cleaning
Depending on the media used, the printer may accumulate residues (media
dust, adhesives, etc.) as a by-product of normal printing. To maintain top
printing quality, remove these residues by cleaning the printer periodically.
WARNING Set the printer power switch to O (Off) prior to performing any cleaning
tasks. Leave the power cord connected to keep the printer grounded
and to reduce the risk of electrostatic damage.
IMPORTANT When the printer is powered off, menu settings that were changed and
not saved permanently and any print data remaining in the print buffer
will be lost. To prevent loss of recent menu changes, see “Saving a
Configuration” on page 148.
CAUTION • Do not wear rings or other metallic objects while cleaning any
interior area of the printer.
• Use only the cleaning agents recommended in this section. Use of
other cleaners may damage the printer and void its warranty.
• Do not spray or drip liquid cleaning solutions directly into the
printer. Apply the solution on a clean lint-free cloth and then apply
the dampened cloth to the printer.
• Do not use canned air in the interior of the printer as it can blow dust
and debris onto sensors and other critical components.
• Only use a vacuum cleaner with a nozzle and hose that are
conductive and grounded to drain off static build up.
• All reference in these procedures for use of isopropyl alcohol
requires that a 99% or greater isopropyl alcohol content be used to
reduce the risk of moisture corrosion to the printhead.
Exterior Cleaning
Clean the exterior surfaces with a clean, lint-free cloth. If necessary, dampen
the cloth with a mild detergent or desktop cleaning solution.
