Zebra Technologies R-140 - Manual (Page 79)

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 solution or desktop cleaner may be used sparingly.
Cleaning the Interior
Inspect this area after every four rolls of media. Remove any 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: You do not need to turn off the printer before cleaning the
printhead. If power is turned off, all label formats and images, as
well as any temporarily saved parameter settings stored in the
printer’s internal memory, will be lost. When power is turned back
on, you will need to reload these items.
To clean the printhead, refer to Figure 25 and follow these steps:
1. Open the printhead.
2. Remove the media and ribbon (if loaded).
3. Moisten an applicator tip with Zebra-recommended solvent and 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 a
few seconds for the solvent to evaporate.
