The E-02 error appears immediately upon printing. If the tape inside the cartridge looks loose, the machine stops to prevent a major internal jam.

Step-by-Step Solution

  1. Remove the tape cartridge from the unit.
  2. Manually rotate the supply spool to remove any slack tape.
  3. Inspect the cartridge for any sticky residue that might be blocking the rollers.
  4. Reinsert the cartridge and press the print button to re-calibrate.

Prevention and Maintenance

Store your label maker in a clean place. Using genuine PX consumables is the best way to ensure sensor accuracy and avoid E-02 errors.
