Common causes

  • 1Physical obstruction: Paper scraps blocking the exit sensor.
  • 2Worn rollers: Uneven feeding causing folds that trigger error.
  • 3Improper loading: Tray guides loose causing misalignment.
  • 4Sensor dust: Toner residue buildup obscuring the optical path.

Solutions

Diagnóstico rápido

The exit sensor is blocked. If the motor engages but no page exits, the jam is likely located in the rear fuser area or the exit transport unit.

Solución paso a paso

  1. Open rear door: Locate any paper scraps behind the rear panel.
  2. Remove paper carefully: Pull in the direction of output.
  3. Clean rollers: Use a lint-free cloth to remove paper dust.
  4. Verify guides: Ensure paper stack is correctly aligned in the tray.

Prevención y mantenimiento

Store paper in a dry place. Avoid wrinkled pages or sheets with staples. Clean feed rollers periodically with distilled water to ensure proper grip.

Cuándo llamar a un técnico

If the error persists after doors are closed and no paper is visible, the exit sensor may be misaligned or broken.

Frequently asked questions

Error 077-901 means a path sensor has detected a stalled sheet, triggering a safety motor shutdown.

Ensure paper guides in the tray are snug and never exceed the recommended loading capacity.

Yes, but low-quality recycled paper generates more dust, which can coat sensors and rollers, leading to more jams.

Yes, provided you pull slowly in the natural direction of transport. Do not force if it remains stuck.
