How To Reset Sharp Ar-6020 ((free)) Link

To reset a Sharp AR-6020 , you must enter Simulation Mode using a specific button sequence. This allows you to clear error codes (like H2, H4, or H5) or reset maintenance counters. 🛠️ How to Enter Simulation Mode Press the [#] or [Interrupt] key. Press the [*] (Asterisk) key. Press the [C] (Clear) key. Press the [*] key again.

The display should go blank or show a version number, indicating you are in the service menu. 🔧 Common Reset Codes

Once in Simulation Mode, use these codes to perform specific resets: System/Error Reset (Code 14): Type 14 using the number pad. Press the [Start] button.

Select "Execute" or "Yes" to clear trouble codes like H-series errors. Maintenance Counter Reset (Code 20): Type 20 and press [Start]. Use sub-code 1 to reset the maintenance cycle counter. Developer Counter Reset (Code 24): Type 24 and press [Start].

Use sub-code 7 to reset the developer counter after replacement. Password Reset:

Enter Simulation Mode and use code 30 to delete or change the current administrator password. 💡 Basic Power Cycle

If the machine is just lagging or has a minor glitch, a simple restart is often enough: Press the [Power] button to turn it off.

Open the front cover and toggle the Main Power Switch (located on the bottom left) to OFF. Wait 10 seconds before switching it back on. how to reset sharp ar-6020

Important Disclaimer: There are different types of "resets" for this model. Performing a full reset (especially via Simulation codes) will erase programmed settings and counters. Proceed with caution.

Part 3: Fixing and Resetting Paper Jams (J Code)

A common frustration is a paper jam that persists even after you have removed the paper. The Sharp AR-6020 has several jam codes (J0, J1, J2, J3, J4).

Before resetting, clear all paper:

  1. Open the side cover (right side). Pull out the green levers and remove any crumpled paper.
  2. Open the front cover and pull out the drum/developer unit. Check for paper wrapped around the black drum roller.
  3. Open the paper tray (Tray 1 or 2). Remove the stack, fan the paper, and load it again.
  4. Check the bypass tray (multi-purpose feeder) for folded paper.

To reset the jam indicator:

Note: The Sharp AR-6020 does not have a manual "jam reset button." It relies on sensors. If jams persist after reset, you likely have a broken sensor flag or a worn-out paper feed roller.

Phase 2: The Hard Reset (The Factory Restore)

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 a Sharp AR-6020 , you must

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:

  1. Enter the Code: Stand before the machine. You are going to input a specific sequence of keys to bypass the standard user interface. Press the following keys in rapid succession:

    • [P] (Program) -> [] (Star/Asterisk) -> [C] (Clear) -> [] (Star/Asterisk)

    (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.)*

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

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

    • 18
    • Press the [Start] key.

  4. The Execution: The screen will likely ask for a sub-code or confirmation. You are usually looking for "Execute" or "Start." Part 3: Fixing and Resetting Paper Jams (J

    • Select [1] for the sub-code (if applicable) and press [Start].
    • The machine will process the command. The screen may flicker, or the machine may reset automatically.

  5. 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.

5. Hard Reset (For Service Technicians Only)

A full NVRAM reset clears everything—including copy counts and calibrated settings. Do not do this unless instructed by a technician, as it can degrade copy quality.

To perform a full hardware reset:

  1. Enter service mode (Power off → hold Start + Clear → Power on).
  2. When "P" appears, enter code "62".
  3. Press Start. The display will show a code (e.g., "01").
  4. Enter "00" using the numeric pad.
  5. Press Start. The machine will initialize all memory.
  6. Turn the machine off and on.

After this, you must recalibrate the scanner and developer unit (codes 46-01, 44-02, etc.).

When Should You Reset?

Part 1: The Simple Soft Reset (No Codes)

Before diving into complex button sequences, try the most basic reset. This solves 90% of "freezing" or "unresponsive" issues.

When to use: The screen is frozen, buttons don't respond, or the machine is stuck on a processing loop.

Steps:

  1. Turn off the main power switch located on the left side of the machine.
  2. Unplug the power cord from the wall outlet.
  3. Wait 60 seconds. This allows the capacitors inside the power supply to drain completely.
  4. Plug the machine back in.
  5. Turn the main power switch back on.

This is a hardware reset. It will not clear error counters, but it will reboot the CPU and clear temporary memory glitches.
