To Reset Sharp Ar-6020 ((better)): How

Enter Simulation Mode: [Clear All] -> [Interrupt] -> [Clear] -> [Interrupt] . Enter code and press Start .

This technical guide provides the exact step-by-step procedures to perform a soft reset, clear common error codes (like the maintenance indicator or H-codes), and restore factory defaults. 1. How to Enter Sharp AR-6020 Simulation Mode

Are you trying to clear a or reset the network/IP settings ? Did this issue start after a toner change or a paper jam ?

Select (or ensure it is selected) to confirm a general troubleshooting reset. Press the Start key again to execute the command. Exit Simulation Mode:

The Sharp AR-6020 is a workhorse of a multifunction printer (MFP), known for its durability in small to medium-sized offices. However, like any complex machine, it occasionally runs into issues that require a reset. Whether you are dealing with a flashing "H" error code, a persistent drum light, a toner message that won't go away, or simply a frozen interface, knowing is essential.

Perform this sequence quickly and steadily on the physical control panel: # →right arrow Interrupt →right arrow Clear →right arrow Interrupt

The machine will process the reset command. Once finished, turn the main power switch , wait 10 seconds, and turn it back ON . 3. Reset Maintenance Counter

: Press the main power switch on the side of the machine to the "O" (Off) position.

| 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 |

Result: Most "frozen screen" or "false jam" errors will disappear after this.

If your printer is displaying a maintenance required icon (often a small "man" or "spanner" icon), you can reset the counter through a similar simulation process. Enter Simulation Mode by pressing # →right arrow Interrupt →right arrow C →right arrow Interrupt . Step 2: Enter code 20 and press Start .

Ensure the developer unit and a new toner cartridge are properly installed. Enter . Type 25 and press Start . Type 1 and press Start .

The machine will process the request and automatically return to its ready state.

Here are solutions to some common problems users encounter:

Sometimes the toner is not empty, but the sensor believes it is. You can override this error.

When you replace consumables like the developer powder or the drum kit, the Sharp AR-6020 will not automatically know a new part has been installed. You must reset the internal counters to clear the maintenance LED icons. Resetting Developer Counter (Simulation 24-06) Enter . Type 24 and press Start . Type 06 and press Start .
