Remedying poor print quality

The cause of poor or too light print quality could be a soiled thermal

array. This section describes how to clean the print head.

If this does not improve the print quality, please contact Technical

Support.

 Open the device and pull out the equipment carriage as far as possible

(see chapter “Basic Operation”, section “Opening / closing the device”).

 Turn off the power by unplugging the power supply connector (see section

“Printer control panel”, item 6).

The print head could be hot. Wait a few minutes for print head to cool

down if it has just finished printing.

Press the green lever as far as

possible in the direction shown by the

arrow (1) and then raise the thermal

printing unit as shown by the arrow

(2).

 Wipe off stains, dust or the like, on the heating element of the print head

by using a soft lint-free cloth moistened with pure Isopropyl alcohol (e.g.

ISOPADS).

 Close the printing unit when Isopropyl alcohol has evaporated completed.

 Connect the printer to the power supply unit (see section “Printer control

panel”. item 6).

 Close the device.
