Cleaning Procedures

Remove any accumulated dirt and lint from the interior of the printer using a soft bristle brush 
or vacuum cleaner.

You can minimize printhead wear and maintain print quality with regular preventive measures.

Over time, the movement of media/ribbon across the printhead wears through the protective 
ceramic coating, exposing and eventually damaging the print elements (dots). In order to avoid 
abrasion:

• Clean your printhead frequently and use well-lubricated thermal transfer ribbons with 

packagings optimized to reduce friction.

• Minimize printhead pressure and burn temperature settings by optimizing the balance 

between the two.

• Ensure that the thermal transfer ribbon is as wide or wider than the label media to prevent 

exposing the elements to the more abrasive label material.

For best results, perform the following cleaning procedure after changing every roll of ribbon. 
Inconsistent print quality, such as voids in the bar code or graphics, may indicate a dirty 
printhead.

1. Open the printhead assembly.

2. Remove the media and ribbon.
3. Use the Preventive Maintenance Kit (Zebra part number 47362) or a solution of 

90% Isopropyl alcohol and 10% deionized water and swab. Wipe along the print elements 
from end to end. The print elements are on the brown strip just behind the chrome strip on 
the printhead. Allow the solvent to evaporate.

4. Manually rotate the platen roller and clean thoroughly with solvent and a pad.
5. Brush or vacuum any accumulated paper lint and dust away from the media and ribbon 

paths.

6. Reload media or ribbon, and close the printhead assembly.

Note • The printer can remain on while you are cleaning the printhead. In this way all label 
formats, images, and all temporary parameter settings stored in the printer's internal memory 
are saved. In addition, keep the peel engaged while cleaning the platen roller (media must be 
unloaded to do this) to reduce the risk of bending the tear-off/peel-off bar.

Caution • Ensure that the printhead is fully open and engaged in the up 
position. If the printhead is not latched in the up position, it could fall on your 
hand during the procedure.
