Common Konica Minolta Bizhub Error Codes and How to Fix Them

Konica Minolta Bizhub multifunction printers are designed for high performance, but they can encounter errors that disrupt workflows. Knowing the Konica Minolta Bizhub error codes and their meanings allows you to troubleshoot issues efficiently, minimizing downtime. This guide covers the most frequent error codes, their causes, and step-by-step solutions to get your machine back on track.

1. Fusing & Temperature Errors

Fusing errors occur when the fuser unit, which bonds toner to paper, malfunctions.

  • C3101 – C3104: Fusing temperature abnormality (overheating or insufficient heating).
  • C3911: Fusing motor failure.
  • C3721: Heater lamp failure.

Solution:

  1. Turn off the machine, wait 10 minutes, and restart to reset the fuser.
  2. Check the fuser unit for debris or damage.
  3. For motor or lamp issues, inspect connections or replace faulty components.
  4. If unresolved, contact a certified Konica Minolta technician.

🔧 Pro Tip: Regular fuser maintenance, such as cleaning and checking connections, can prevent temperature errors.

2. Imaging Unit & Toner Issues

Toner and imaging unit errors affect print quality and machine functionality.

  • C2557: Waste toner box full.
  • C2558: Toner density abnormality.
  • C255C: Incorrect or incompatible toner installed.
  • C2559: Toner cartridge not detected.

Solution:

  1. Replace the waste toner box if full.
  2. Ensure the toner cartridge is genuine Konica Minolta and properly seated.
  3. For density issues, clean the toner path and run a calibration from the control panel.
  4. If the cartridge isn’t detected, reseat it or try a new one.
  5. Reset the error code in service mode (instructions below).

💡 Toner Tip: Always use OEM (original equipment manufacturer) toner to avoid compatibility errors like C255C.

3. Paper Jam & Feeding Issues

Paper feed errors are common in busy offices and often involve jams or motor issues.

  • C0202 – C0206: Paper feed motor errors.
  • C0211: Paper transport failure.
  • C0300 – C0304: Tray lift motor error (paper tray not lifting properly).
  • C0500 – C0504: Fusing unit paper jam detection.

Solution:

  1. Open the machine and gently remove any jammed paper.
  2. Clean feed rollers with a lint-free cloth and isopropyl alcohol.
  3. Verify paper is loaded correctly and within tray specifications.
  4. For motor or tray errors, check for obstructions or loose connections.
  5. Consult a technician for persistent motor-related issues.

🔍 Quick Fix: Use high-quality, properly stored paper to reduce the risk of jams in Bizhub models.

4. Communication & Network Errors

Network and communication errors disrupt printing, scanning, or internal operations.

  • C-E301: HDD communication error.
  • C-D010: Abnormal memory error.
  • C-E002: Network connection issue.
  • C-E301: Print controller communication failure.

Solution:

  1. Restart the machine to clear temporary glitches.
  2. For network errors, check cables, Wi-Fi settings, and IP configuration.
  3. Update firmware from the Konica Minolta website to resolve communication issues.
  4. For HDD or memory errors, power off and reseat components if accessible.
  5. Contact IT support or a technician for advanced diagnostics.

🌐 Network Tip: Ensure your Bizhub is on a stable network with proper firewall settings to avoid C-E002 errors.

5. Developer & Drum Unit Issues

These errors affect the imaging process, impacting print quality and consistency.

  • C2152: Drum motor failure.
  • C2201 – C2204: Developer unit failure.
  • C2251: Imaging unit error.

Solution:

  1. Inspect the drum and developer units for wear or toner buildup.
  2. Replace the imaging unit if it’s nearing the end of its lifespan.
  3. Clean connections and reseat the units to rule out loose contacts.
  4. Reset the error in service mode (see below).
  5. For motor failures, professional servicing is recommended.

📋 Maintenance Tip: Schedule regular drum and developer unit checks to prevent costly replacements.

6. Scanner & Optical System Errors

Scanner errors affect document scanning and copying functions.

  • C6700: Scanner motor failure.
  • C6750: Exposure lamp failure.

Solution:

  1. Restart the machine to reset the scanner system.
  2. Check for obstructions in the scanner path or document feeder.
  3. For lamp errors, inspect the exposure lamp and replace if faulty.
  4. If motor issues persist, contact a technician for scanner assembly repair.

⚠️ Important: Keep the scanner glass clean to avoid misreads that could trigger errors.
