Cleaning Information

Danger!
Risk of death via electrocution!
 Disconnect the printer from the power supply before performing any maintenance tasks.
The label printer requires very little maintenance.
It is important to clean the thermal printhead regularly. This guarantees a consistently well 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 fluff from the print area with a soft brush or vacuum cleaner.
 The cover of the printer can be cleaned with a standard cleaner.
