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, you should 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 and any print data remaining in the print buffer will be lost. To prevent the
loss of recent menu changes, see Configuration setting on page 49.
•
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, use a mild detergent or desktop
cleaning solution.

Interior Cleaning

Clean the interior of the printer by removing any dirt and lint with a vacuum cleaner, as described above, or
use a brush with soft non-metallic bristles.

Cleaning the Printhead, Platen Roller, Media Sensors/Damper

NOTE: Even though the printhead, platen roller, media sensors and media damper are individually
listed in these cleaning procedures, debris and adhesive on these components can ultimately
travel to the printhead area and therefore should be cleaned and examined each time the
printhead is cleaned and in the order shown.

Printhead Cleaning

As you use your printer, the printhead may become dirty with ribbon residue and label adhesives which can
result in poor print quality. Keeping the printhead clean will help maintain its life.
•
Cleaning Agent - Clean the printhead using a Printhead Cleaning Pen, Printronix PN 203502-002
or an Isopropyl Alcohol Wipe, Printronix PN 254945-901.
•
Schedule - Clean the printhead each time you install a new roll of ribbon (thermal transfer print
mode) or when you install a new roll or box of media (direct thermal print mode).
