Common causes

  • 1Physical obstruction: Objects or paper blocking the carriage movement.
  • 2Dirty rail: Dust accumulation increases movement friction.
  • 3Belt misalignment: The positioning belt has slipped or loosened.
  • 4Home sensor failure: Sensor cannot detect when the carriage reaches the start point.

Solutions

Quick Diagnosis

If the print carriage bangs against the sides or stops abruptly in the middle, the E-04 error will trigger. Check for any loose cables or paper scraps that may impede movement from right to left.

Step-by-step Solution

  1. Power off and unplug: Turn off and remove the power cord.
  2. Check carriage: Open the lid. Gently move the carriage. If you feel an obstacle, remove any trapped paper scraps.
  3. Clean rail: Use a dry cloth to clean accumulated dust from the carriage path.
  4. Power on: Reconnect and power on. The unit will attempt to re-locate its home position.

Prevention and Maintenance

Do not print in locations prone to vibration. Ensure ink tubes are not kinked, as they can obstruct the carriage during operation.

When to Call a Technician

If clearing the rail and checking for obstructions doesn't clear the error, the carriage belt or the stepper motor might be failing, requiring professional repair.
