Solutions

Quick Diagnosis

If the status light flashes and the carriage does not move, the printer has likely triggered an internal safety stop. Check if the print head is stuck on one side.

Step-by-Step Solution

  1. Power off and unplug the printer.
  2. Gently move the carriage left and right to feel for resistance.
  3. Clean the encoder strip with a dry, lint-free cloth.
  4. Power on the printer to reset the sensor calibration.

Prevention and Maintenance

Keep the printer in a clean environment to avoid dust accumulation. Use genuine 502 ink bottles to maintain print head health.

When to Call a Technician

If the carriage still fails to home after cleaning, the motor assembly may be internally damaged.
