A common reason people search for "how to reset sharp ar-6020" is the dreaded "H3" or "H4" error. This means the fuser unit failed to reach temperature. Never ignore H errors – they are fire safety locks.

How to clear H3/H4 on Sharp AR-6020:

Use the arrow keys to navigate to Simulation 14.

This clears the fuser error latch. The machine will attempt to reheat.

Exit Service Mode by turning the machine off and on.

Warning: If H3/H4 returns immediately, your fuser lamp or thermostat is broken. Do not keep resetting it – call a technician.

Use this when the spanner/wrench light is solid or blinking.

To reset the developer counter (if you changed the developer):

If the machine is asking for a code: If the machine displays "Enter Account Code" or "Department Code," it is in Account Control mode. If you do not know the code, you must contact your IT administrator. If you are the administrator, you can disable this in System Settings > Account Control (the default password is often 00000).

If "Call for Service" appears: If a code like U2, H4, or F5 appears, a simple power reset may not work. how to reset sharp ar-6020

To reset the Sharp AR-6020, you must Simulation Mode using a specific key sequence to clear maintenance counters or technical error codes The Reset Procedure

The most common reset for this model involves clearing maintenance counters or "trouble" codes (like the H4 error) through the service menu. Enter Simulation Mode : Press the following keys in quick succession: right arrow [Interrupt] right arrow right arrow [Interrupt] Note: On some regional versions, the sequence is right arrow [Interrupt] right arrow right arrow [Interrupt] Select the Reset Category Use the number pad to enter and press the again to clear the maintenance counter. Clear Specific Errors (e.g., H4) If you are clearing a fuser or system error, enter code in Simulation Mode and press . This is the "Trouble Clear" command. Exit Simulation : Press the (Clear All) key to return to normal operation. Types of Resets

Depending on your specific issue, you may need a different approach: Maintenance Reset

: Required when the maintenance indicator (spanner icon) stays lit after servicing. Use Simulation as described above. Developer Initialization

: If you have just replaced the developer powder, you must run Simulation for exactly two minutes to calibrate the new material. Paper Jam Reset

: Simply opening and closing the side or front cover often clears standard jams. If the error persists, check the Sharp AR-6020 Operation Guide for sensor cleaning instructions. Resetting Network/System Settings For software-related issues or network configuration: Default Password

: If you are locked out of the web interface, the factory default administrator password is typically Web Console Print this table and keep it near your

: Access the printer's IP address in a browser to perform a "System Reset" via the administrator settings menu.

: Turn off the power button on the control panel. Open the front cover and toggle the main power switch (near the waste toner box) to off. Wait 10 seconds before switching it back on to clear temporary memory. Clear Error Codes (H2, H5, etc.) Enter Simulation Mode by pressing: [#] → [Interrupt] → [C] → [Interrupt] in quick succession. Once the display goes blank, enter code using the keypad.

The machine will initialize and reboot, clearing the active error. Reset Maintenance Counters Access Simulation Mode ( [#] → [Interrupt] → [C] → [Interrupt] to reset the drum counter or for developer initialization. Admin & Network Resets Default Credentials

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. A common reason people search for "how to

Before trying anything drastic, perform a soft reset. This clears temporary memory glitches without affecting settings.

How to do it:

If the error returns within 24 hours:

Need a service manual? Sharp does not publicly release full service codes, but Simulation Modes 42, 44, and 14 cover 90% of AR-6020 reset needs.

Disclaimer: Resetting the maintenance counter without replacing parts will void any remaining warranty and leads to poor print quality. Perform at your own risk.

Because "reset" can mean different things depending on the problem you are facing, this guide covers the three most common types of resets: a hard reboot (for glitches), a factory reset (for settings), and a maintenance reset (for service codes).

This returns the machine to default settings (paper size, energy save, etc.). It does NOT clear the maintenance counter.
