Unacceptable Print Quality - Datamax M-Class Mark II M-4206 Operator's Manual

Unacceptable print quality

Dirty printhead: Clean the printhead (see Chapter 5).
The temperature setting may be incorrect for the media being used: Use the software program or DPL
commands adjust the Heat Setting and Print Speed.
A mismatched incorrect ribbon/media combination is being used: Check the types being used.
Verify that the Media Type is set correctly for the printing method being used (see Chapter 4).
Faulty printhead: Replace it (see Chapter 5) or call for service.
The printer does not print or prints several labels at once:
The labels are incorrectly loaded: See the loading instructions on the inside cover of the printer or Chapter 3.
The media is not calibrated: Calibrate it (see Chapter 4).
The Media Sensor may need to be repositioned (see Chapter 3).
The media sensor or sensor circuitry may be defective: Call for service.
The ribbon does not advance
(The paper advances, but ribbon does not).
The ribbon may be installed incorrectly: Ensure that the ribbon's inked side faces the paper. With most
ribbons this can be verified by rubbing paper against the ribbon; the ink should smudge the paper. Or, if using
label stock, the sticky side of a label will pull off the ink.
A mismatched ribbon/paper combination is resulting in an insufficient amount of friction between paper and
ribbon: Ensure that the correct type of ribbon is being used with the media.
