 Disconnect the printer from the electricity supply before starting 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 fluff from the print area with a soft brush or vacuum cleaner.
 The cover of the printer can be cleaned with a standard cleanser.

hand. Use a soft cloth and roller cleaner for cleaning.
