Common causes

  • 1Defective or poor-quality communication cable.
  • 2Incorrect IP address assignment in network mode.
  • 3Corrupted driver stack on host server.
  • 4Communication port physically damaged by surge.

Solutions

Quick Diagnosis

If the error occurs constantly, check if the device shows as 'Offline' on your host PC. A faulty cable or duplicate IP address is frequently the root cause.

Step-by-Step Solution

  1. Physical Check: Unplug and reconnect the communication cable (USB or LAN) at both ends.
  2. Change Port: Try connecting the printer to a different port on your PC or a different network switch.
  3. Restart Spooler: Restart the Windows print spooler service to clear pending jobs.
  4. Hardware Test: Print a self-test label from the printer's internal menu to rule out mainboard logic failures.

Prevention and Maintenance

Use high-quality shielded cables to avoid electrical interference. Update the firmware periodically to ensure connection stability.

When to Call a Technician

If the E-405 persists after testing with new cables and different ports, the communication port on the logic board may be damaged.
