Cleaning the Print Roller

A soiled print roll can lead to reduced print quality and can affect transport of material.

Cleaning the Printhead

Printing can cause accumulation of dirt at printhead e.g. by colour particles of transfer ribbon, and therefore it is necessary to
clean the printhead in regular periods depending on operating hours, environmental effects such as dust etc.
CAUTION!
Printhead can be damaged!

Do not use sharp or hard objects to clean the printhead.

Do not touch protective glass layer of the printhead.

Open the printer cover.

Turn red lever counter clockwise to lift up the printhead.

Remove labels and transfer ribbon from the label printer.

Clean printhead surface with special cleaning pen or a cotton swab dipped in pure alcohol.

Allow printhead to dry for 2-3 minutes before commissioning the printer.

Cleaning the Label Photocell

CAUTION!
Label photocell can be damaged!

Do not use sharp or hard objects or solvents to clean the label photocell.
The label photocell can become dirtied with paper dust and this can adversely affect label detection.
