Before you engage in the drastic measure of a factory reset, you must attempt the soft reset. This clears the temporary memory (RAM) without erasing your settings or stored addresses.
If the problem persists—if the "Call for Service" code remains or the network refuses to connect—you must proceed to the deeper, more permanent solution.
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.
To reset a Sharp AR-6020 digital multifunctional system, you must enter the machine's "Simulation Mode" to clear specific error codes or maintenance counters. The exact steps depend on whether you are clearing a general system error or a maintenance light. General System Error Reset (e.g., H2, H4 codes)
If your machine is stuck with a blinking red light or an error code like , follow these steps to perform a "Trouble Cancellation": Enter Simulation Mode
: On the control panel, quickly press the following sequence: . (Note: Some variants use [Interrupt] [Interrupt] Input Program Code : Use the numeric keypad to enter Execute Reset : Press the
(Green) button. The display should show "SIMULATION 14 TROUBLE CANCELLATION". again. When asked "ARE YOU SURE?", press once more to confirm.
: Turn the machine off and then back on to return to normal operating mode. Maintenance Counter Reset When the maintenance light (frequently code
) appears, it indicates the machine has reached a predefined copy count and requires servicing. Enter Simulation Mode Access Counters : Enter code Clear Specific Counters to clear the maintenance counter. : Press the how to reset sharp ar-6020
(Clear All) button twice to exit simulation mode and return to the main screen. Common Reset Codes for Maintenance : Resets the main maintenance counter. : Resets the drum counter. : Resets the developer counter. Troubleshooting Tips Error Persists : If a code like
reappears immediately after a reset, it often indicates a physical hardware failure (such as a blown thermistor or broken fuser cable) that must be repaired before the code can be permanently cleared. Paper Jams
: Basic paper jam errors can often be cleared simply by opening and closing the front cover or side panel once the obstruction is removed. for this model or a guide on replacing the toner/developer How to reset Maintenance Counter Sharp AR -6020v
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: Before you engage in the drastic measure of
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.
Watch these guides to see the button sequences and maintenance menus in action:
To reset a Sharp AR-6020, you typically need to access its Service Mode (Simulation Mode). The specific reset procedure depends on whether you are trying to clear a general error code (like H4) or reset the maintenance counter after servicing. 1. Access Simulation Mode
Most Sharp AR-series reset procedures begin with this button sequence: Press the [Interrupt] key. Press the [Clear] (C) key. Press the [Interrupt] key again. Press the [Clear] (C) key again.
The display should go blank or show a prompt, indicating you are in simulation mode. 2. Clear System Errors (e.g., H4 Error) To clear common fuser or system errors: Enter 14 using the number pad. Press the [Start] button.
The machine will process the reset command. Once finished, turn the main power switch OFF, wait 10 seconds, and turn it back ON. 3. Reset Maintenance Counter If the problem persists—if the "Call for Service"
If you have replaced parts and need to clear the maintenance light: Enter 42 in simulation mode and press [Start]. Enter 1 and press [Start] to clear the counter. 4. Reset Admin Password
If the device is networked (AR-6020N) and you need to reset the web interface or admin settings:
The default username is admin and the default password is admin (all lowercase) or Sharp (with a capital S).
To reset a custom password via the panel, use Simulation 30-1 or check the specific system settings menu if the "Maintenance" light is not on.
Note: If an error code like H4 returns immediately after a reset, it usually indicates a hardware failure (such as a blown fuser lamp or faulty thermistor) that requires physical repair.

Best for: Clearing persistent error codes (like "H4", "F2"), resetting the developer counter, or resetting the drum counter.
This is a more advanced reset used by technicians. Proceed with caution; changing settings in Simulation Mode can cause hardware issues if done incorrectly.
