Common causes

  • 1Loose paper debris in the print carriage path.
  • 2Dirty encoder strip blocking sensor vision.
  • 3Wear and tear on carriage rails.
  • 4Faulty carriage motor positioning.

Solutions

Quick Diagnostics

A rhythmic clicking or grinding noise while the carriage moves confirms that a physical obstruction or worn part is causing the stop.

Step-by-Step Solution

  1. Power off and unplug the printer.
  2. Open the access door and remove any paper scraps.
  3. Clean the encoder strip (the clear plastic belt behind the carriage) using a lint-free cloth.
  4. Manually check for resistance by sliding the carriage back and forth.
  5. Restart to perform a new home-positioning cycle.

Prevention and Maintenance

Keep the internal path free of dust and debris. Do not stack paper unevenly, as this causes jams near the carriage path. Regular maintenance of the roller assembly is highly recommended.

When to Call a Technician

If the carriage travels smoothly after cleaning but the error persists, the encoder sensor or main board is likely malfunctioning.
