Error C-4501 Konica Minolta bizhub C3320i: Solution

The konica-minolta bizhub c3320i error c-4501 points to a deficiency in the scanner exposure lamp. When the lamp does not illuminate properly, the system cannot capture document data and throws this security code. To fix the c-4501 error on bizhub c3320i, it is important to check if the light turns on when initiating the copy process, allowing you to differentiate between a connection error or a complete lamp exhaustion.

Common causes

  • 1End of the exposure lamp's lifespan.
  • 2Inverter or lighting controller failure.
  • 3Voltage spike that has burnt the lamp circuit.
  • 4Loose internal connection in the scanner data bus.

Solutions

Diagnóstico rápido

If you try to make a copy and observe the scanner moving, but the internal light doesn't shine or flickers weakly, the C-4501 confirms the lamp has reached the end of its life or has a power failure.

Solución paso a paso

  1. Cool down: Turn off the device and let it rest for 15 minutes.
  2. Observation: Open the scanner lid, press "Start", and look under the glass to see if you can see flickering light.
  3. Restart: Perform a full restart of the machine to rule out a controller error.
  4. Verification: If the light remains off, the optical component is faulty.

Prevención y mantenimiento

Using a voltage regulator is essential for this unit; power surges are the leading cause of early lamp degradation. Keep the glass free of grease spots that force the scanner to work at higher intensities.

Cuándo llamar a un técnico

The scanner lamp replacement is a precision operation. If the error persists after following these steps, the lamp must be replaced by a professional to ensure even lighting.

Frequently asked questions

Error C-4501 occurs when the system detects that the scanner lamp does not reach the light intensity required for digitization.

It is a hardware failure that is rarely fixed with software, but a restart allows ruling out temporary voltage issues.

No, the device can continue printing from the computer without issues, but it will not be able to copy or scan.

Use quality voltage stabilizers to avoid spikes that damage the lifespan of the scanner lighting system.
