is highly effective for clearing configurations or troubleshooting persistent errors, but it requires careful handling of the internal hard drive (HDD). Reset Methods & Performance
Full Initialization (Recommended for Wiping): This is the deepest reset, accessed via the Service Mode (Utility > Counter > Stop 00 Stop 01). It clears all settings, including network and user data, but disables the hard drive. You must manually re-enable and reinstall the HDD in the "System 2" menu afterward to restore full functionality.
Network-Only Reset: Ideal if you've lost connectivity or want to clear old IP settings without wiping the whole machine. This is done through Administrator Mode > Maintenance > Reset > Network Setting Clear.
Trouble Reset: If you are dealing with a specific error code (like a fuser error), a physical button reset is often more effective than a software factory reset. You hold the Yellow Reset Button while powering on until a black dot appears on the screen. Review: Pros & Cons Pros Cons
Comprehensive: Wipes all personal data, user boxes, and address books—essential for machine resale.
Complex Recovery: Full initialization requires technical steps to re-enable the HDD and potentially reinstall "movie" files for the help animations.
Fixes Glitches: Effective at resolving deep-seated firmware or network configuration conflicts.
Hidden Menus: Requires knowledge of service codes (like Stop 00 Stop 01) which are not in the standard user manual. Important Credentials
To perform these resets, you will likely need the default passwords: Administrator Password: Typically 12345678 (twice).
Service Mode Password: Often 92729272 (four times) depending on the firmware version.

, a "factory reset" can mean anything from clearing network settings to a full system initialization that wipes all user data. Depending on your goal—troubleshooting an error or prepping the machine for disposal—choose the appropriate procedure below. 1. Full System Initialization (Service Mode)
This is the most comprehensive reset. It clears all system settings and user data but does not reset the life counters (meter readings). Accessing Service Mode: Press the Utility button on the control panel. Select Counter > Display Keypad. Enter the sequence: Stop, 0, 0, Stop, 0, 1. Initialization Steps: In the Service Mode menu, select System 1. Tap Initialization.
Select Clear All Data to reset all settings and erase user information. Press the Start button on the keypad.
Post-Reset Action: A full initialization will often disable the hard drive (HDD). You must re-enable it by navigating to System 2 > HDD > Installed, then restart the machine. 2. Network Setting Reset (Administrator Mode)
Use this if you only need to clear IP addresses, DNS settings, or scan-to-email configurations. Press Utility > Administrator Settings.
Enter the administrator password (default is typically 1234567812345678 or 12345678). Navigate to Maintenance > Reset > Network Setting Clear.
Tap Clear and confirm with OK. Restart the machine to apply. 3. Data Sanitization (HDD Wipe)
If you are disposing of the machine and need to ensure all latent data on the hard drive is unrecoverable: In Administrator Settings, go to Security Settings. Select HDD Management Setting > Delete All Data Setting. If you are troubleshooting a persistent error code,
Choose an Erase Mode (e.g., Mode 1 for a quick wipe or higher modes for more secure overwriting) and press Execute Deletion. 4. Trouble Reset (Error Clearing)
If the machine is locked by a specific service code (like a fuser error), a "Trouble Reset" may be required to reboot the system into a functional state. Turn the main power OFF.
Press and hold the Yellow Reset Button on the control panel.
Turn the power ON while continuing to hold the reset button until a black dot appears in the top right of the screen.
When the Trouble Reset screen appears, tap Trouble Reset and then OK. Restart the machine.

To perform a factory reset on a Konica Minolta bizhub C258, you can use the Administrator Settings for a standard reset or the Service Mode for a more comprehensive initialization. Note that a full initialization may disable the hard drive, requiring it to be re-installed in the system settings afterward. Method 1: Standard Factory Reset (Administrator Mode)
This method resets general machine settings to their factory defaults. Press the Utility/Counter button on the control panel.
Select Administrator Settings and enter the default password (typically 12345678 or 1234567812345678). Navigate to System Setting. Select Default Machine Setting. Press Start to reset all settings to factory default. Press Return once the process is complete. Method 2: Full Initialization (Service Mode)
Use this for a deeper reset that clears all data and history. Press Utility/Counter and then select Display Keypad.
Enter the following sequence quickly: Stop → 0 → 0 → Stop → 0 → 1. In the Service Mode menu, select System 1. Select Initialization.
Choose Clear All Data to reset everything, or select specific items like Network Settings or Fax Data to clear them individually. Follow the on-screen prompts to restart the machine. Method 3: Resetting Specific Components
Resetting a Konica Minolta bizhub C258 typically falls into three categories depending on your goal: a Network/Settings Reset (Standard), a Full Data Wipe/Initialization (Deep), or a Trouble Reset (for error codes). 1. Basic Network & Setting Reset (Administrator Mode)
This method is best for reconfiguring the machine without wiping the hard drive. Step 1: Press the Utility button on the control panel.
Step 2: Tap Administrator Settings and enter the password (default is 1234567812345678 or 12345678). Step 3: Navigate to Maintenance → Reset.
Step 4: Select Network Setting Clear or Default Machine Setting and press Start/Clear. 2. Full Factory Initialization (Service Mode)
This "Deep Reset" clears all user data and settings but often disables the hard drive as a safety measure, requiring you to re-enable it afterward. This requires entering Service Mode
Enter Service Mode: Press Utility → Counter → Display Keypad. Then press Stop, 0, 0, Stop, 0, 1. Initialize: Select System 1 → Initialization.
Wipe: Choose Clear All Data and press Start. The machine will reboot.
Re-enable HDD: If the screen shows the hard drive is "Not Installed" after rebooting, return to Service Mode, go to System 2 → HDD, and select Installed. 3. Trouble Reset (Clearing Error Codes)
The Non-Volatile RAM holds the machine’s counters, serial communication settings, and adjustment values. Corrupt NVRAM causes "C-" series error codes (e.g., C2152, C9401). A factory reset via software won't fix hardware-related logic errors—but an NVRAM reset will.
Warning: This resets the life counters for drums, developer, and fuser. Do not use this to fraudulently "renew" a machine—it leads to print quality disasters.
Step-by-Step Instructions:
After this, you must run Stabilization and Gradation Adjustment:
| Your Goal | Recommended Method | | :--- | :--- | | Forgot admin password / Fix settings conflict | Method 1: Reset All Data | | Selling the machine / Privacy compliance (GDPR) | Method 2: HDD Format + Firmware | | Machine won't boot / C-Dxxx error codes | Method 3: NVRAM Reset + Stabilization | | Moving to a different network only | Skip reset. Use Network Settings Reset in Admin Mode. |
The Konica Minolta bizhub C258 is a robust platform, but it relies on clean software to run smoothly. Performing a factory reset every 12-18 months—especially in high-volume environments—prevents ghosting, slow UI response, and failed saves.
If you have performed the steps above and still face issues, your machine may have a failing Solid State Drive (SSD) or damaged main board. In that case, a factory reset is not a repair; contact a Konica Minolta authorized service technician.
Disclaimer: This guide is for informational purposes. Service Mode modifications may void warranties if performed incorrectly. Proceed at your own risk.
Older bizhub C258 units accumulate digital clutter. A "Reset All Data" does not always purge the hard drive’s hidden sectors. For a true, secure factory reset—especially before selling the machine—you must format the HDD and reinitialize the file system.
Warning: This deletes everything permanently. Do not attempt this if you use HDD Encryption (you must decrypt first to avoid bricking the drive).
Step-by-Step Instructions:
Select "Logical Format":
Rebuild the File System:
Install the System Software (Crucial Step):
This is the only method that returns the machine to a "virgin" state, as if fresh from the factory.
If the standard menus are locked or corrupted, you may need to enter Service Mode. Caution is advised here; changing settings other than the reset can damage the machine.
