Diagnóstico rápido

The error 31.01 occurs when feeding from the main tray. If no paper is visible, the issue is often a small scrap of paper blocking the registration sensor flag, tricking the printer into thinking there is an obstruction.

Solución paso a paso

  1. Access Internal Areas: Open all trays and doors as prompted by the control panel.
  2. Manual Removal: Pull paper out smoothly without using metal tools that could damage rollers.
  3. Check for Debris: Use a flashlight to find tiny corners or label scraps stuck in the path.
  4. Sensor Reset: Close all doors firmly so the system can run an auto-calibration cycle.

Prevención y mantenimiento

Only use fresh, dry paper in the trays. Keep the tray area dust-free and clean the pickup rollers periodically. Authentic toner cartridges and good paper quality prevent these mechanical errors.
