Cleaning Procedures
To clean the printhead and platen roller, complete these steps:
1. Refer to Figure 34. 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.
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.
Note • If performing this procedure does not improve print quality, 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.
