If the status indicator is blinking unexpectedly while printing via mobile, the connection has likely timed out. The E-01 error usually requires re-establishing the handshake between the host device and the printer.

Step-by-Step Solution

  1. Remove the printer from your mobile phone or PC Bluetooth device list.
  2. Perform a hard reset by holding the power button for 10 seconds while the unit is off.
  3. Put the printer back into pairing mode (Bluetooth LED flashing).
  4. Connect again from your host device and initiate a test print.

Prevention and Maintenance

Keep your printer's firmware updated to handle modern Bluetooth protocols. Avoid operating near high-interference zones. Ensure high-quality thermal media is used to minimize printhead friction.
