| Problem | Reset Method | Speed | | :--- | :--- | :--- | | Frozen screen, ignoring buttons | Power cycle (unplug) | Fast | | Red "Drum" light after new drum | Drum counter reset (Method 2) | 30 sec | | Red "Toner" light with new toner | Toner gear check + code | 1 min | | H3 / H4 error (fuser) | Simulation 14 | 1 min | | Corrupted settings / Selling device | Factory reset (Simulation 67) | 2 min | | False paper jam | Jam clear (Simulation 8) | 30 sec |
| 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 you are selling the machine or it has corrupted settings, perform a full factory reset. This clears copy counts, tray settings, language preferences, and network defaults.
Sharp AR-6020 Factory Reset via Service Mode:
What this resets:
Caution: Do not run Simulation 67 unless you are absolutely sure you want to wipe everything. how to reset sharp ar-6020
Use this when the spanner/wrench light is solid or blinking.
To reset the developer counter (if you changed the developer):
The Sharp AR-6020 is a workhorse of an office copier—known for its durability and straightforward operation. However, like any precision machine, it will eventually ask for attention. Whether you’ve just replaced the toner cartridge, cleared a paper jam, or want to wipe custom settings, knowing the correct reset sequence is crucial.
Below, we break down every reset procedure for the AR-6020, from simple button pushes to hidden service codes.
Best for: Clearing all user settings, wiping the address book, restoring network settings to default, or preparing the machine for a new office environment. | Problem | Reset Method | Speed |
Warning: This will erase all stored data, including scan-to-email addresses and fax numbers.
Sharp does not always place the full factory reset option in the standard user menu to prevent accidental data loss. However, you can try the following standard method:
Steps:
Note: If this option is grayed out or unavailable, the machine may require a "Simulation Mode" reset (see section 3).
The AR-6020 does not automatically detect a new toner cartridge every time. If the machine still shows "Toner Empty" after installing a new cartridge, you need to manually reset the toner count. | Reset Goal | Simulation Code | Effect
How to reset toner:
Note: If the machine does not respond, turn the main power off, wait 10 seconds, and repeat the steps with the power on.
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).
