Solutions

Quick Diagnosis

If you hear grinding sounds or see the carriage struggling to move, the Z4 error is triggered as a safety measure. Always check for paper snags first.

Step-by-step solution

  1. Unplug the power cord immediately.
  2. Clear the rear path by opening the paper jam door.
  3. Remove any obstacles such as paper scraps or foreign objects.
  4. Manually push the print head to check for smooth movement.
  5. Restart the printer to complete the diagnostic test.

Prevention and Maintenance

Use dry and clean paper only. Perform routine roller dusting to prevent slip in the feed mechanism.

When to call a technician

If the error returns after clearing all debris, the issue may lie with the encoder strip or the printer motor assembly, which requires professional service.
