Fix C-5101 Error Konica Minolta bizhub 758e: Paper Lift Issue

The C-5101 error on the Konica Minolta bizhub 758e is associated with an anomaly in the main paper tray lift motor. When this motor fails to raise the paper platform to the feeding position, the unit locks. The solution usually involves verifying the affected tray and clearing potential hidden jams.

Common causes

  • 1Physical obstruction from paper scraps in the lift mechanism.
  • 2Wear of drive gears preventing tray movement.
  • 3Electrical failure in the lift motor due to overload.
  • 4Misaligned or defective tray presence sensor.

Solutions

Diagnóstico rápido

The C-5101 will appear if the machine attempts to feed paper and the tray does not respond to the upward movement. Check if the tray is overloaded or if folded sheets are interfering with the lift mechanism.

Solución paso a paso

  1. Remove the affected paper tray and check that no paper scraps are in the rails.
  2. Manually inspect the lift mechanism to see if it moves smoothly without resistance.
  3. Clean feed rollers with a cloth lightly dampened with isopropyl alcohol to improve traction.
  4. Reinsert the tray, ensuring it fits correctly into the side guides.

Prevención y mantenimiento

Do not exceed the tray's maximum capacity, as excess weight stresses the motor and can blow internal mechanism fuses. Perform monthly cleanings of feed rollers to prevent paper dust from causing slippage or jams.

Cuándo llamar a un técnico

If the lift mechanism does not respond when activating the test sensor (Service Mode) after tray removal, the lift motor may have failed electrically. Professional service is required to replace the motor or drive gears.

Steps to follow

  1. 1

    Tray Extraction

    Completely extract the tray marked with the error to inspect the internal slot.

  2. 2

    Rail Cleaning

    Remove any paper residue blocking the movement of the lift platform.

  3. 3

    Motor Test

    Use service mode to send a lift signal and verify the motor's operation noise.

  4. 4

    Alignment

    Re-insert the tray, verifying that the side sensors detect the closed position.

Frequently asked questions

It is a moderate error that prevents printing from a specific tray. It does not affect system function but limits paper capacity.

Removing and re-inserting the tray correctly often solves the alignment issue. If not, power cycling the machine helps.

You should check the feed rollers (pick-up rollers), which wear down with constant paper usage.

Yes, but ensure you adjust the paper type in the panel; an incorrect setting strains the feeding mechanisms.
