Method 2: The HDD Format (The "Deep Clean" Factory Reset)

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).

1. Enter Service Mode (Counter -> Stop,0,0,Stop,0,1).

2. Go to "System 1":

   • Tap System 1.
   • Tap HDD Setting.

3. Select "Logical Format":

   • Choose Logical Format. (Do not choose Physical Format unless you have 4+ hours to wait).
   • It will ask for a "Format Capacity." Select All Area.
   • Press Start.

4. Rebuild the File System:

   • After the format finishes (approx. 3-5 minutes), exit back to the main Service Menu.
   • Go back to System 1 -> Initialize.
   • Select HDD. Press Start.

5. Install the System Software (Crucial Step):

   • After an HDD format on a C258, the machine cannot boot normally. You will see a "System Error" or "No HDD."
   • You must reload the Firmware via USB. Download the latest A5CH0Y0-F000-GXX-XX firmware from the Konica Minolta support site.
   • Insert USB, turn off/on while holding the Utility key to enter Recovery Mode, and flash the firmware.
