Cleaning Information
Danger: Risk of death via electric shock! Disconnect the printer from the power supply before
performing any maintenance work.
The label printer requires very little maintenance.
It is important to clean the thermal printhead regularly. This guarantees a consistently good
printed image and plays a major part in preventing premature wear of the printhead.
Otherwise, the maintenance is limited to monthly cleaning of the device.
Attention: The printer can be damaged by aggressive cleansers. Do not use abrasive
cleaners or solvents for cleaning the external surfaces or modules.
• Remove dust and paper fibers from the print area with a soft brush or vacuum cleaner.
• The cover of the printer can be cleaned with a standard cleanser.
Cleaning the Print Roller
Accumulations of dirt on the print roller may impair the media transport and the print quality.
• Lift the printhead.
• Remove labels and transfer ribbon from the printer.
• Remove deposits with roller cleaner and a soft cloth.
• If the roller appears damaged, replace it. Refer to the Service Guide.
Cleaning the Printhead
Substances may accumulate on the printhead during printing and adversely affect printing, e.g.
differences in contrast or vertical stripes.
