Cleaning The Printhead, Platen Roller And Media
Sensors
Printhead Cleaning
As you use your SLPA, the printhead may become dirty which can result in
poor print quality. Clean the printhead each time you install new ribbon
(thermal transfer print mode) or install new media (direct thermal print mode).
Clean the printhead with the cleaning pen supplied with the SLPA or with a
cotton swab moistened with alcohol.
By keeping your printhead clean, you will help maintain its life.
Platen Roller Cleaning
Media dust and adhesive residue on the platen roller can degrade print quality
and cause voids in your label image. Clean the platen roller at the same time
as the printhead.
Use a small amount of isopropyl alcohol on a cloth to clean the platen roller.
With the pivoting deck up the platen roller can be rotated forward by hand to
access and clean its entire surface area.
IMPORTANT
Do not use sharp objects such as a knife or screwdriver to remove stuck
labels.
Media Sensor Cleaning
The Upper and Lower Media Sensors should be cleaned to ensure reliable
TOF and paper out sensing. Clean the media sensors at the same time as the
printhead.
The Upper Media Sensor (located in the horizontal slot of the printhead cover)
can be wiped clean using a soft cloth. The Lower Media Sensor, easily seen
by its visible red light, is located in the horizontal slot of the media guard.
Remove media dust by vacuuming or blowing air across the lens cover.

Cleaning Procedure

1. Set the power switch to O (Off) and let the SLPA cool for 5 minutes.
2. Rotate the deck lock lever clockwise to open the pivoting deck and
remove any media and ribbon (if loaded) to gain access to the printhead
assembly heating element area.
3. Gently rub the felt tip of the cleaning pen or a cotton swab moistened with
isopropyl alcohol across the printhead heating elements (light brown
area).
4. Allow the printhead to dry for one minute before reloading the media and
ribbon.
5. Clean the platen roller.
6. Clean the upper and lower media sensors.
