Zebra-Specific Troubleshooting Steps
Label Recalibration
Sometimes the ink on the label is cut off as if the label printer does not know the size of the label. In these cases, try a label recalibration:
Press and hold the Feed button until the green status light flashes once, then twice
Release the Feed button
The roll will automatically feed until a label is positioned.
Press the Feed button. One blank label will print
Here is a video to demonstrate. This should reset the size of the label so the printer prints properly.
Printer Factory Reset
To completely start fresh, you can perform a printer factory reset:
Press and hold the Feed button until the green status light flashes once, then twice, and then continuing until the flash groups reach the group of four flashes
Release the Feed button
The roll will automatically feed until a label is positioned
Press the Feed button. One blank label will print
After a factory reset always do a label recalibration as described above
Printing Blank Labels: Full Calibration
Very rarely, a printer may print blank labels between print jobs. To fully recalibrate the printer, perform a full calibration:
Press and hold the Feed button until the green status light flashes once, then twice, and then continuing until the flash groups reach the group of seven flashes
Release the Feed button
The roll will automatically feed until a label is positioned
A profile of the media sensor settings will print
Press the Feed button. One blank label will print
Zebra Printer Labels Too Dark/Bold/Blury
If your labels are printing out too dark/bold and the barcode is not scannable, follow these steps:
Press and hold the Feed button until the green status light flashes once, then twice, and then continuing until the flash groups reach the group of six flashes
Release the Feed button
The printer will print out labels with the various darkness settings
Once the label with your preferred setting prints out, press the feed button again
