Step-by-Step Solution

  1. Visual Check: Open the access door and look for any strange objects blocking the path.
  2. Encoder Cleaning: Clean the transparent strip (encoder strip) with a damp cloth without harsh chemicals.
  3. Guide Maintenance: Apply a fine lubricant to the metal rod to reduce friction.
  4. Reset: Reconnect the power and let the unit attempt the initial calibration.

Prevention and Maintenance

Keep the printer away from dusty areas. Always use original cartridges, as heavy or poorly fitted cartridges generate extra friction on the carriage.

Yes, the encoder strip is very fragile. If you scratch it while cleaning, the printer will not be able to position the head.

Use HP 63 cartridges. Lack of ink in one of them can also confuse the carriage sensor.

It is recommended to perform an external cleaning and check the interior every 6 months to prevent paper dust accumulation.
