Carriage Error: Encoder Strip Malfunction

Severity:High Severity
Affected:18 models

What This Error Means

This error indicates a problem with the encoder strip, a clear plastic strip that tells the carriage its position. If dirty or damaged, the printer cannot track carriage movement accurately.

Common Causes
  • 1Encoder strip is dirty with ink, dust, or debris, obstructing the optical sensor's ability to read the lines.
  • 2Encoder strip is physically damaged (creased, scratched, torn, or detached from its mounting points), leading to inaccurate position feedback.
  • 3The carriage assembly's encoder sensor (optical sensor) itself is faulty or misaligned, failing to correctly read the encoder strip.
  • 4Contamination or damage to the carriage motor's encoder disk or sensor, which can indirectly affect carriage positioning feedback.
  • 5Excessive friction or obstruction in the carriage path preventing smooth movement, causing the carriage to stall and trigger a position error.
Symptoms to Watch For
  • Printer displays error code '23:10' on the front panel.
  • Carriage movement is erratic, jerky, or completely stalled.
  • Print quality issues such as vertical banding, misaligned lines, or distorted images.
  • Printer makes unusual grinding or squealing noises during carriage movement.
  • The carriage assembly repeatedly attempts to move but fails to reach its home or service station position.
Basic Troubleshooting Steps
1. Turn off the printer and unplug it. 2. Open the top cover. 3. Locate the clear plastic encoder strip running across the printer behind the carriage. 4. Gently clean it with a lint-free cloth and water. 5. Plug in and restart the printer. If damaged, it needs replacement.
