Canon PIXMA G4270 Error 1890: Fix Paper Jams and Obstructions

The 1890 error on the Canon PIXMA G4270 occurs when the position sensor detects an object or material blocking the print head carriage movement. This is usually caused by scrap paper, staples, or debris in the paper path. The solution involves a careful visual inspection and removal of any foreign objects.

Common causes

  • 1Scrap paper jamming the carriage path.
  • 2Foreign objects like staples or clips dropped in the tray.
  • 3Accumulation of dust on the encoder strip affecting position tracking.
  • 4Motor gears stuck due to lack of lubrication or debris build-up.

Solutions

Diagnóstico rápido

If you hear grinding noises while the carriage attempts to move, the 1890 error is signaling a physical blockage. Use a flashlight to inspect the carriage rail and the internal print path for debris.

Solución paso a paso

  1. Unplug the unit to allow the carriage to be moved manually without electrical resistance.
  2. Slide the carriage gently toward the center, avoiding contact with the thin transparent encoder strip.
  3. Inspect the path and remove any paper fragments or debris obstructing the roller area.
  4. Clean the rail with a dry, lint-free cloth if there is visible dust build-up preventing smooth movement.

Prevención y mantenimiento

Always use proper paper weight and size settings. Keep the paper tray closed when not in use to prevent foreign objects from falling inside. Clean the rollers annually to maintain proper grip.

Cuándo llamar a un técnico

If the error persists after clearing all visible obstructions, the carriage motor might be damaged or the encoder strip could be faulty, requiring professional repair.

Steps to follow

  1. 1

    Power Off

    Disconnect the power supply to ensure the carriage can be handled safely.

  2. 2

    Visual Check

  4. 4

    Test Mobility

    Slide the carriage back and forth to ensure it glides without friction.

Frequently asked questions

Usually, no. It is typically just a physical blockage. Only persistent grinding after clearing the path suggests hardware damage.

Do not force it. If it doesn't budge, the blockage might be internal and professional disassembly is recommended.

Using original GI-11 inks helps prevent internal messes that could collect dust and lead to mechanical issues over time.

Adjust paper guides tightly against the stack and ensure paper isn't bent or damaged before loading.
