How To Reset Sharp Ar-6020 -

In the quiet corner of the busy office sat the Sharp AR-6020, a reliable workhorse that suddenly went on strike. It wasn't just a paper jam this time; a stubborn error code blinked on the display, and the machine refused to budge. The team needed it back online, and fast. Entering the Secret Menu

To fix it, you first have to enter the machine’s "Service Mode"—a hidden realm for technicians. It starts with a rhythmic sequence: pressing

again in quick succession. The display goes blank, signaling that the copier is ready for its secret commands. Banishing the Error Codes

The most common "reset" needed for the AR-6020 is clearing a trouble code, like the dreaded . Once in Service Mode: Use the keypad to enter the magic number:

The machine begins to initialize, clearing the internal error memory and restarting itself. When it powers back up, the red light is gone, and it's ready to copy once more. Resetting the Counters

Sometimes, the machine just needs a fresh start with its maintenance life. After entering Service Mode with the Interrupt-C-Interrupt

sequence, technicians use simulation codes to reset the maintenance counters, ensuring the "sun" icon for developer replacement or service vanishes after the work is done. A New Password

There was even the time the office forgot the admin password. They had to press a special button for 10 seconds until "1 3 0" appeared, then enter a sequence of , followed by to wipe the slate clean and set a new code. With the final press of the

If your machine is displaying an error code such as H2, H3, or H4, it often indicates a fuser-related issue that requires a manual clear through the service mode. According to various technical guides, follow these steps to reset:

Enter Service Mode: On the control panel, press the following buttons in sequence: # → * → C → *. This sequence must be done relatively quickly to access the "Simulation" mode [5.1].

Select Simulation 14: Once the display allows input, enter the number 14 using the keypad [5.21].

Execute the Reset: Press the Start button (the Black & White copy button) [5.21].

Restart: The machine will typically cycle through a brief initialization. Once complete, turn the power off and then back on. If the error was temporary (e.g., a power surge), the machine should now be clear and ready for use [5.1, 5.12]. 2. Resetting to Factory Defaults

To reset general settings, such as networking or administrative configurations, to their original factory state: Access the System Settings menu on the display [5.4]. Navigate to Storing/Calling of System Settings [5.4].

Select Restore Factory Defaults and confirm the prompt [5.4].

Note that the default administrator username is often admin and the password is sharp (case-sensitive) [5.24]. 3. Clearing Mechanical Errors (Paper Jams and E7)

Some "resets" are mechanical. For example, an E7 error usually relates to the scanner glass or lens being unable to find its home position. Instead of a code reset, you must physically clean the scanner glass, lens, or sensor to allow the machine to reset itself during its next startup cycle [5.2]. For misfeeds or paper jams (often indicated by a CH or blinking red light), ensure all doors are opened and any lodged paper is removed before the machine will resume normal operations [5.11, 5.16].

Safety Note: If an error code like H4 (fuser trouble) returns immediately after a reset, do not continue resetting it. This indicates a physical component failure—such as a blown fuser lamp or faulty thermistor—that requires professional repair to avoid a fire hazard [5.7, 5.12]. AI responses may include mistakes.

1. The Soft Reset (Clearing Errors)

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

How to do it:

  1. Press the Clear button (yellow key with an "X") on the control panel.
  2. Press the Stop button twice.
  3. If the machine is frozen, turn it off using the main power switch (not the wall outlet), wait 30 seconds, and turn it back on.

Still Having Issues?

If the error returns within 24 hours:

  1. Replace the drum unit (life is ~20,000 pages).
  2. Check the toner cartridge – is it genuine Sharp?
  3. Clean the corona wire (small green lever under the drum unit – slide back and forth 5 times).

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.

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 The machine is not responding to button presses

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.

Are you currently seeing a specific error code on the display that you need help troubleshooting?

This guide covers the three most common types of resets: Toner Reset, Maintenance/Timer Reset, and Factory Settings Reset.

Part 4: Hard Reset (Factory Reset / NVRAM Clear)

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.

Steps:

  1. Enter Simulation Mode (Clear + Interrupt + Power ON).
  2. Type 6 6 (Simulation 66).
  3. Press Start. The display will show 66-01.
  4. Press the 1 key (for full NVRAM reset).
  5. Press Start. The display will show 1 and then END.
  6. Turn the machine OFF/ON.

After a hard reset, you must reconfigure your paper size (usually Letter or A4) and cassette settings. To set paper size:

Part 3: Fixing and Resetting Paper Jams (J Code)

A common frustration is a paper jam that persists even after you have removed the paper. The Sharp AR-6020 has several jam codes (J0, J1, J2, J3, J4).

Before resetting, clear all paper:

  1. Open the side cover (right side). Pull out the green levers and remove any crumpled paper.
  2. Open the front cover and pull out the drum/developer unit. Check for paper wrapped around the black drum roller.
  3. Open the paper tray (Tray 1 or 2). Remove the stack, fan the paper, and load it again.
  4. Check the bypass tray (multi-purpose feeder) for folded paper.

To reset the jam indicator:

Note: The Sharp AR-6020 does not have a manual "jam reset button." It relies on sensors. If jams persist after reset, you likely have a broken sensor flag or a worn-out paper feed roller.

4. Factory Settings Reset (Network & User Settings)

If you need to erase all custom settings (e.g., default copy density, paper size, auto power-off timer), perform a user settings reset. This does NOT clear the maintenance counter.

To restore factory defaults:

  1. Press and hold the Copy Ratio key (down arrow) for 5 seconds. You will hear a beep.
  2. Use the arrow keys to scroll through the menu until you see "22" (Factory Reset).
  3. Press OK or Start.
  4. The display will show "YES" (use arrow key to select) then press OK.
  5. The machine will beep three times and restart.
