Solutions

Quick Diagnosis

If the red error lamp blinks, check the position of your labels relative to the sensor path.

Step-by-step Solution

  1. Alignment: Adjust side guides so the label sits flat in the sensor path.
  2. Calibration: Perform the media calibration wizard from the printer menu.
  3. Sensors: Wipe the label sensor clean of any adhesive residue.

Prevention and Maintenance

Clean sensors periodically with a dry brush. Only use media that meets the opacity specifications for your unit.

When to Call a Technician

If calibration fails repeatedly, the physical media sensor may need replacement.
