Cleaning the Exterior
The exterior surfaces of the printer may be cleaned with a lint-free cloth. Do not use
harsh or abrasive cleaning agents or solvents. If necessary, a mild detergent or
desktop cleaner may be used sparingly.
Cleaning the Interior
Remove any accumulated dirt and lint from the interior of the printer using a soft
bristle brush and/or vacuum cleaner.
Cleaning the Printhead and Platen Roller
Inconsistent print quality, such as voids in the bar code or graphics, may indicate a
dirty printhead. For best results, perform the following cleaning procedure after
every roll of ribbon.
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 will be
saved.
To clean the printhead, refer to Figure 23 and follow these steps:
1. Open the printhead assembly.
2. Remove the media and ribbon (if loaded).
3. Using a swab soaked in the Zebra-recommended solvent, 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 sufficient time for the solvent to
evaporate.
4. Manually rotate the platen roller and clean thoroughly with solvent and a swab.
5. Brush/vacuum any accumulated paper lint and dust away from the media and
ribbon paths.
6. Reload media and/or ribbon, and close the printhead assembly.
