Technical information

Inconsistent print quality, such as voids in the bar code or graphics, may indicate
a dirty printhead. For optimum performance, Zebra recommends performing the
following cleaning procedure after every roll of ribbon.
NOTE: When cleaning the Printhead, it is not necessary to turn Printer Power OFF. If
Power is turned OFF, all label formats and images, as well as any temporarily
saved parameter settings, will be lost. When Power is turned back ON, it will be
necessary to reload these items. (Label formats and images stored in the optional
Battery Backed-Up Static RAM will not be lost if Power is turned OFF.)
1. Raise the Media Compartment Door and lower the Front Door.
2. Open the Printhead by moving the Printhead Release Lever to the OPEN position.
3. Remove the media and ribbon (if present) from the printhead area.
4. Moisten an applicator tip with Zebra Technologies Corporation-
recommended solvent (part # 01426) and wipe the print element from end to
end. See Fig. 4.1. The print element is the grayish/black strip just behind
the chrome strip on the printhead). Allow a few seconds for the solvent to
evaporate.
5. Apply solvent (part # 01426) to a lint-free cloth. Manually rotate the Platen
Roller and clean thoroughly with solvent.
6. Brush/vacuum any accumulated paper lint and dust from within the printer,
paying close attention to the rollers and media sensor areas.
7. Reload ribbon and/or media, close and latch the Printhead Release Lever,
restore power if previously turned OFF, and continue printing.
CAUTION: No lubricating agents of any kind are required on this printer.
Some commercially available lubricants will damage the finish if used.
