Zebra barcode printer printed label has white stripe, how to solve?

The label printed by the zebra barcode printer appears white bars, which may be caused by a variety of reasons. In order to solve this problem, you can follow the following steps to troubleshoot and repair:

First, check the installation of carbon tape and label paper

Verify that the carbon tape and label paper match each other and are suitable for your Zebra barcode printer model.

Check whether the carbon tape or ribbon is inverted, which may result in white strips printed.

Reinstall the carbon tape and label according to the quick installation guide provided with the package to ensure correct installation.

Second, adjust the position of the paper sensor

Lift the print head and check to see if there is a paper detector where the paper passes through.

Make sure the paper detector is covered with paper so that the printer can correctly sense the size of the paper.

If the detector is not positioned correctly, its position needs to be adjusted to cover the entire label paper.

Third, check the label paper Settings and actual size

In the software for editing label paper, go to the Paper TAB of Page Settings.

Check whether the setting of the label is consistent with the actual size. If they are inconsistent, you need to reset them.

It is recommended to use a ruler to measure the actual height of the label paper before printing to ensure that the label is set correctly.

4. Clean the paper sensor

If the paper sensor is dirty, it may cause white strips to print. In this case, power off the printer.

Clean the paper sensor with anhydrous alcohol to ensure that its surface is clean and free of stains.

After the cleaning is complete, re-operate the "Paper Probe", press the FEED key with the printer on standby and hold it for 3 seconds, waiting for the 3 LED indicators to flash at the same time.

Five, check the label paper quality and gap

Make sure that the gap between the label paper is standardized, and there is no difference in size or spacing due to processing reasons.

Check whether the label paper is too thick or irregular, which may cause the printer to be unable to sense the size of the paper.

6. Contact suppliers for maintenance

If none of the above methods can solve the problem, the paper sensor may be faulty. Contact the supplier to repair or replace the parts.

In summary, to solve the problem of white strips printed by zebra barcode printers needs to be investigated and repaired from multiple aspects. After following the above steps, the problem should be resolved.
