Section 4 Maintenance
Clean the Printhead
Inconsistent print quality such as voids in the bar codes or graphics may indicate a dirty
printhead. For optimum performance, the printhead should be cleaned regularly.
Zebra Technologies recommends performing the cleaning procedure when installing a
new roll of ribbon, when installing a new roll of direct thermal media, or after printing
500 feet (150 m) of continuous or fanfold media.
It is not necessary to turn the printer Off (O) prior to cleaning. If printer is turned Off (O),
all label formats, images, and parameter settings stored in the printer’s formatting RAM
memory will be lost. Permanent parameter settings stored in EEPROM or Flash are
retained. When the printer is turned On (l), it may be necessary to reload some items into
the memory.
Use the following procedure to clean the printhead:
1. Open the printhead by moving the printhead lever to the open position.
2. Remove the media and ribbon.
3. Refer to Figure 4-1. Moisten a cleaning swab with solvent and wipe the print
elements from end to end. The print elements are the greyish black strip just behind
the chrome strip on the underside of the printhead. Allow a few seconds for the
solvent to evaporate.
4. Rotate the platen roller and clean thoroughly with a solvent and an applicator.
5. Brush or vacuum any accumulated paper lint and dust away from the rollers and the
media and ribbon sensors.
6. Reload ribbon and media, close and latch the printhead, restore power, and run the
Pause Key Self Test to check print quality.
