Press the button again to execute the clearing command.
: 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].
If you are searching for 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.
The display should go blank or show a version number, indicating you are in the service menu. 🔧 Common Reset Codes
Keep the machine off for at least 60 seconds to allow the internal memory to discharge. how to reset sharp ar-6020
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.
If an error code immediately returns after performing a simulation reset, the printer is detecting a physical hardware failure rather than a software glitch.
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.
When your copier displays persistent error symbols—such as the (little wrench), the Developer Replacement icon , or H-codes (fuser errors) —a standard power cycle will not clear them. You must enter Sharp’s backend Service Simulation Mode to clear these flags. Press the button again to execute the clearing command
To perform almost any reset on the Sharp AR-6020, you must first access the machine's backend via the . Follow this exact sequence on the physical control panel:
If you need to reset specific settings back to their defaults, you have two options:
Do not change any simulation numbers other than the ones specified below. Ensure no print jobs are currently in the queue.
Press the power button above the screen and wait for the display to go blank. If you are searching for you are likely
If you are servicing the toner and need the machine to recalibrate density references after maintenance, key in 2 followed by 5 . Use the sub-code 02 and press Start . Phase 3: Exiting Service Mode
Once a technician has replaced consumables like the drum or developer, the maintenance indicators (like the "sun" icon ☼) must be 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
Allow the machine to complete its warming-up cycle. 2. Resetting Network and System Settings (Admin Level)
Note: Some models use a different sequence like -> [Auto/Density] -> [C] -> [Auto/Density] until the screen blanks.
Reconnect the cable directly to the wall outlet (avoid extension cords) and flip the power switch back on. 2. Accessing Sharp AR-6020 Simulation Mode
