  • 3Carriage motor fatigue: Mechanical failure preventing normal movement.
  • 4Improper cartridge installation: Cartridges not seated correctly interrupting the path.

Solutions

Quick Diagnosis

If you hear grinding noises from your printer or the carriage hits a wall, you are likely facing the 0x61000021 error. Look for small paper bits or sticker residues trapped on the rails.

Step-by-Step Solution

  1. Disconnect the power cable while the printer is powered on to disengage the carriage.
  2. Open the cartridge access door and manually move the carriage back and forth to find obstructions.
  3. Clean the encoder strip with a clean, lint-free cloth if grease or ink spots are visible.
  4. Reconnect the printer and allow it to perform the automatic startup sequence.

Prevention and Maintenance

Avoid using damaged labels or wrinkled paper. Perform internal cleaning every six months using low-pressure compressed air. Always use original HP 902 cartridges to maintain optimal printhead health.
