Konica Minolta AccurioPress C4070 Error C-5102: Diagnosis

The Konica Minolta AccurioPress C4070 error C-5102 occurs when the system identifies a failure in the paper tray lift motor mechanism. If the platform cannot reach the operating height, the machine stops printing to prevent paper jams or component damage. This is often caused by overloading the tray or paper debris interfering with the gears.

Common causes

  • 1Overloaded paper trays putting strain on the lift motor.
  • 2Debris or paper scraps blocking the gear-driven lift mechanism.
  • 3End-of-life failure of the paper tray motor assembly.
  • 4Improperly adjusted side guides causing uneven pressure and friction.

Solutions

Quick Diagnosis

The error appears upon attempting to print from a specific tray. Check if the platform attempts to move upwards or if there is a straining sound from the tray area, which suggests the motor is active but unable to move the weight.

Step-by-Step Solution

  1. Remove the tray fully and ensure the stack is perfectly flat.
  2. Clear debris by checking the area beneath and behind the tray for paper scraps.
  3. Adjust side guides to ensure there is just enough slack for the media to move without getting pinched.
  4. Close the tray completely until the sensor confirms it is seated properly and restart the unit.

Prevention and Maintenance

Do not exceed the tray capacity marks indicated on the guide. Use high-quality paper media to reduce internal debris accumulation. Clean rollers and the internal tray mechanism at least every six months.

When to Call a Technician

If the tray lift motor remains unresponsive or sounds as though it is 'slipping' after cleaning and resetting, you may have a broken gear or motor failure. Contact your professional service partner to avoid further damage to the printer feed assembly.

Steps to follow

  1. 1

    Adjust the paper tray

    Pull out the affected tray and check that the paper guides are not too tight against the media.

  2. 2

    Visual inspection

    Check for any paper scraps or debris inside the tray mechanism that might prevent lifting.

  3. 3

    Reset the system

    Close the tray firmly and restart the printer to allow the motor to attempt another lift cycle.

Frequently asked questions

The C-5102 error is specific to the paper tray lift motor. It means the platform failed to reach the required printing height, triggering a safety halt.

Yes, it interrupts print workflows as the printer cannot access the paper in that specific tray, needing immediate resolution.

Yes, using media that exceeds the weight specifications or improperly loading heavy stacks can overload the lift motor.

Regularly clean the feed rollers and always ensure the paper is fanned and within the tray limit marks to avoid motor strain.
