6.1 Cleaning Information
DANGER!
Risk of death via electric shock!
Disconnect the printer from the power
supply before performing any mainte-
nance work.
The label printer requires very little maintenance.
It is important to clean the thermal printhead regu-
larly. This guarantees a consistently good printed im-
age 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 cleans-
ers.
Do not use abrasive cleaners or solvents for clean-
ing the external surfaces or modules.
