clear system error Konica c360 220 280 423 363 283
To clear a persistent service trouble code on a Konica Minolta bizhub C220, C280, C360, 283, 363, or 423 machine, you must run a physical hardware reset. First, turn the machine’s main power switch completely OFF. Open the small door on the right side of the control panel to locate the physical Trouble Reset button (or hold the Utility/Counter key on some variants), and turn the main power switch back ON while holding it down. Once the “Trouble Reset” screen appears, tap the Trouble Reset option on the panel, verify it says “OK”, and reboot the machine to restore normal operation.
