How To Reset Sharp Ar-6020 Online

Before diving into the steps, identify your problem. The AR-6020 requires different reset procedures based on the symptom:

Let’s start with the simplest, safest methods and move to advanced service resets.

To reset the maintenance counters, you need to enter "Simulation Mode" (service mode).

Step-by-step entry:

Warning: This is the point of no return. Performing a full system reset will restore the Sharp AR-6020 to the state it was in when it left the factory. It will erase your network settings (IP address, subnet mask), your address book, and any custom presets. Ensure you have this information backed up or accessible before proceeding.

To reset the AR-6020, you must enter the Simulation Mode. This is the technician’s backdoor, a diagnostic realm where the machine’s core behaviors can be altered.

The Ritual:

(Note: On some AR-6020 interfaces, the keys may be labeled slightly differently, or you may need to use the number pad to simulate the commands, but the P--C-* sequence is the industry standard for Sharp.)*

  • The Gateway: If done correctly, the display will change. It will ask for a Main Code or simply enter a "Simulation Mode" screen.

  • The Purge Command: You are looking for the simulation code that handles system initialization. Using the number keypad, type:

  • The Execution: The screen will likely ask for a sub-code or confirmation. You are usually looking for "Execute" or "Start."

  • The Confirmation: Once the machine restarts, it will likely prompt you to set the initial settings (Date, Time, Language). This is the sign that the amnesia has been successful. The machine remembers nothing; it is innocent again.

    • If you see H2, H3, H4 (fuser/heater errors), or U2 (EEPROM error), do not run a normal reset. You must clear the specific trouble code:

    To clear H2-H4 (Fuser errors):

    To clear U2-30 / U2-40 (EEPROM checksum error):

    If you need to erase all custom settings (e.g., default copy density, paper size, auto power-off timer), perform a user settings reset. This does NOT clear the maintenance counter.

    To restore factory defaults:

    Print this table and keep it near your machine:

    | Symptom | Button Sequence | | :-- | :-- | | Service mode entry | # * C * | | Clear fuser error (H3/H4) | Service mode → 14 → Start | | Clear drum light | C C 20 → hold Copy Ratio | | Factory reset | Service mode → 67 → Start → 1 → Start | | Exit service mode | Turn OFF power |
