Zebra Technologies Z4M manual Cleaning the Exterior, Cleaning the Interior

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.
