not every situation is addressed, you may find some tips helpful. After a correction action is taken press
the
button to clear the alarm.
Unacceptable print quality:

Dirty printhead: Clean the printhead (see Section 4.2).

The temperature setting may be incorrect for the media being used: Use the configuration utility
or software commands adjust the Heat Setting and Print Speed.

Faulty printhead, call for service.
The printer does not print or prints several labels at once:

The labels are incorrectly loaded: See the loading instructions in Section 2.3.

The media is not calibrated: Calibrate it (see Section 3.4).

The media sensor or sensor circuitry may be defective: Call for service.
Skips every other label (print quality is good, but every other label is skipped):

The label is formatted too close to the top edge of the label: Leave white space equal to 8-dot
rows (about .02 inch [.5mm]) at the top of the label.

The media is not calibrated: Calibrate it (see Section 3.4).

The media sensor or media sensor circuitry may be defective: Call for service.
Unable to print rotations:

The characters are formatted outside the dimensions of the label: Check that the row/column
values provide enough room for the height of the image being printed.
