RESOLUTION / ANSWER

CALIBRATION: Ensures correct and consistent positioning of the print on the label and the label in the printer.

Symptoms addressed by this solution include: 

• The printer prints, then skip a label or skipping labels.
• The print is overlapping onto the next label.
• Print position is drifting up and down on the labels.
• Labels stop printing in random locations.
• The printer prints labels then the light starts to flash.
   

Calibrate the printer for the media.

The printer does not measure the label length unless the default Power Up or Head Close values are altered to either Length or Calibrate.

There are two calibration methods to consider if the labels fail to calibrate properly.

• The 2 Flash Feed Button sequence will find the label gap and measure the label.
• The 7 Flash Feed Button performs a deeper analysis of the gap or mark and will produce a media sensor profile.
