Error Cal-Error Honeywell PC42t: Calibration failure

The Honeywell PC42t error Cal-Error occurs when the printer cannot determine label length or position due to a sensor calibration failure. This issue prevents proper alignment of the printed design, causing the text to drift or print continuously over multiple labels. To resolve Cal-Error in PC42t, it is vital to verify that material is loaded correctly and that the optical sensor is free of adhesive residue or dust.

Common causes

  • 1Accumulation of label adhesive on the optical sensor.
  • 2Misaligned paper that fails to break the sensor's light beam.
  • 3Use of poor-quality labels with low-contrast black marks.
  • 4Incorrect sensitivity parameters saved in memory.

Solutions

Quick Diagnosis

If the printer does not stop at the end of each label or shows a solid red light, the sensor sensitivity is likely inadequate for the installed material.

Step-by-Step Solution

  1. Ensure the paper is properly aligned and passes under the label sensor.
  2. Press and hold the 'Feed' button while turning on the printer until the LED flashes amber.
  3. Release the button to allow the printer to feed a few labels and automatically adjust the sensor threshold.
  4. If the error persists, clean the sensor with a cotton swab lightly dampened with isopropyl alcohol.

Prevention and Maintenance

Clean sensors after every label roll. Use only certified thermal paper for this model and avoid touching the optical sensor surface, as finger oils can alter accuracy.

When to Call a Technician

If the sensor still fails to detect paper after performing the automatic calibration process, the sensor's infrared light is likely broken or the mainboard needs repair.

Steps to follow

  1. 1

    Correct loading

    Ensure the paper is properly aligned and passes under the label sensor.

  2. 2

    Calibration mode

    Press and hold the 'Feed' button while turning on the printer until the LED flashes.

  3. 3

    Confirmation

    The printer will automatically feed a few labels to adjust the sensor threshold.

Frequently asked questions

It indicates that the optical sensors cannot detect gaps between labels or the positioning black mark.

It is necessary so the printer can stop at the correct position when printing individual labels.

Using high-quality labels and original Honeywell ribbon is recommended to avoid sensor residue.

Whenever you change the label roll or if you notice the printer skipping spaces unnecessarily.
