How To Reset Sharp Ar-6020 -

The Sharp AR-6020 uses a developer unit (developer mix) that should last ~60,000 pages. Some online guides incorrectly advise resetting the developer counter when changing toner. Do not do this. Resetting the developer counter (Simulation 42) without replacing the developer powder will lead to light copies, backgrounding, and streaks.

If you have actually replaced the developer unit, you reset it via:

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. how to reset sharp ar-6020

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 Sharp AR-6020 uses a developer unit (developer

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. Warning: This is the point of no return

If the machine is locked up, shows a non-fatal error (like "F" codes, misfeed memory, or developer required), use the Simulation 16 method.

Steps:

If the standard simulation codes do not work, or if you are facing a persistent "Call for Service" code (like an H4 or H5 error, which denote fuser or laser unit issues), the standard user reset may be locked. In this scenario, you access the deeper service mode.

This guide covers the three most common types of resets: Toner Reset, Maintenance/Timer Reset, and Factory Settings Reset.
