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.
To clean the printhead, refer to Figure 4-1 and follow these steps:
1. Open the media door and then 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, close the printhead assembly, and close the media door.
Caution • Observe proper electrostatic safety precautions when handling any
static-sensitive components such as circuit boards and printheads.
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.
Note • Ensure printhead is in the fully upright position and latched.
Note • Do not use sharp objects to clean printhead or platen rollers.
Note • If print quality has not improved after performing this procedure, try
cleaning the printhead with Save-a-Printhead cleaning film. This specially
coated material removes contamination buildup without damaging the
printhead. Call your authorized Zebra reseller for more information.
