Select the specific counter to reset (e.g., for the main maintenance counter). button to clear the count. 3. Reset Admin Password If you have forgotten the admin password for the Sharp AR-6020N/D , you can reset it via simulation Enter Simulation Mode. Change the value from 130 to to delete the existing password. to set a new password. Standard Hard Restart
If the machine is just acting strangely without a specific error code, perform a clean power cycle: button on the panel and wait for the screen to go dark. Open the front panel and toggle the Main Power Switch (usually bottom left) to
Wait at least 30 seconds before flipping the main switch back to If an error like
reappears immediately after a reset, it likely indicates a physical hardware failure in the fuser unit that requires part replacement. Are you seeing a specific error code on the display that you need to clear? How to reset Maintenance Counter Sharp AR -6020v how to reset sharp ar-6020
To reset the Sharp AR-6020, you must access the device's simulation (service) mode to clear specific error codes or maintenance counters. The general reset procedure involves entering a hidden key sequence followed by specific command codes. 1. Entering Simulation Mode
To begin any reset process on the Sharp AR-6020, you must first enter the Simulation Mode by pressing the following keys in rapid succession: # (Hash) INTERRUPT CLEAR (C) INTERRUPT
If entered correctly, the display will go blank or show a specific simulation prompt, indicating the machine is ready for service commands. 2. Resetting Common Error Codes (Trouble Clear)
Many "fuser" errors (such as H2, H3, or H4) lock the machine for safety. To clear these errors after a repair: Enter Simulation Mode (as described above). Type 14 using the numeric keypad. Press the START button.
The machine will initialize and clear the error state. If successful, turn the main power switch off, wait 10 seconds, and turn it back on. 3. Resetting Maintenance Counters
Once a technician has replaced consumables like the drum or developer, the maintenance indicators (like the "sun" icon ☼) must be reset: Maintenance Counter Reset: Enter Simulation Mode. Type 20 and press START. Type 01 and press START to execute the reset. Developer Counter Reset: Enter Simulation Mode. Type 24 and press START. Type 06 and press START to reset the developer counter. 4. Resetting the Admin Password
If you are locked out of the web interface or administrative settings: The default username is typically admin.
The default password is often admin or sharp (case-sensitive).
To perform a physical password reset, technicians use Simulation 30 (sub-code 01) to clear existing passwords and return them to factory defaults. Summary of Common Simulation Codes Simulation Code Clear Fuser Errors Maintenance Reset Developer Reset Drum Counter Reset Clear Password
Note: If an error code like H4 reappears immediately after a reset, it usually indicates a hardware failure (like a blown thermistor or fuser lamp) that must be physically repaired before the reset will hold. To reset the Sharp AR-6020 , you typically
Are you currently seeing a specific error code on the display that you need help troubleshooting?
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.
The Sharp AR-6020 is a workhorse in many small to medium-sized offices. Known for its durability and low cost per copy, it handles high volumes of printing, copying, and scanning. However, like all office equipment, it will eventually display error codes, maintenance reminders, or simply freeze up.
If you are searching for "how to reset Sharp AR-6020," you are likely dealing with one of three issues: a maintenance indicator (yellow light or "H" code), a fatal error code (U2, F2, L4, etc.) , or a paper jam that won't clear. This guide walks you through every method to reset your machine, from simple soft resets to advanced maintenance counter resets using simulation codes.
Disclaimer: Performing a reset on a Sharp AR-6020 should be done carefully. Some resets (specifically simulation 24 and 42) zero out critical counters. Do not perform these unless you have physically replaced the corresponding maintenance parts (drum, developer, fuser).
Sometimes the AR-6020 insists there's a jam even after you've removed all paper. This requires a jam memory reset.
Steps:
Clear (C) button repeatedly until the jam display disappears.# * C *) and run Simulation 8 (Jam Cancel). Click Start and then exit.Warning: This will erase all user settings (default paper size, contrast settings, auto-shutoff timer, network settings if applicable). Use only as a last resort.
This resets the Non-Volatile RAM (NVRAM) back to factory default. Try Simulation 14 (as described above) to clear the error
Steps:
Clear + Interrupt + Power ON).6 6 (Simulation 66).Start. The display will show 66-01.1 key (for full NVRAM reset).Start. The display will show 1 and then END.After a hard reset, you must reconfigure your paper size (usually Letter or A4) and cassette settings. To set paper size:
1 for Letter, 2 for A4, etc.Start, then turn OFF/ON.| Reset Goal | Simulation Code | Effect |
|------------|----------------|--------|
| Clear general error (F/CH) | 16 | Auto adjusts developer & toner |
| Factory reset (all settings) | 56 (option 1) | Wipes user settings |
| Fuser error (H2-H4) | 14 (01) | Resets heater trouble |
| EEPROM error (U2) | 16 | Checksum recovery |
| Developer counter | 25 (01) | Resets "Dev Required" |
| Paper jam memory | 08 (01) | Clears phantom jam |
If these steps do not work, the issue is likely hardware-related (broken fuser, dead developer motor, or main board failure). Contact a Sharp service technician.
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
