How To Reset Sharp Ar-6020 «WORKING 2025»

After approximately 60,000 copies, the AR-6020 will display "H2", "H3", "H4", or "Maintenance Required". This is a timed counter, not necessarily a hardware failure. You can reset it using the service program.

Step-by-step maintenance reset:

The "Maintenance Required" message should now be cleared.

If your Sharp AR-6020 is flashing a red "Maintenance Required" light, showing a F code on the display, or simply refusing to copy, you likely need to perform a reset. Unlike a home printer, this office workhorse requires a specific button sequence (often called "Simulation Mode") to clear internal counters.

Warning: Performing a full reset will clear the drum counter, developer counter, and maintenance timer. Do this only after you have physically replaced the drum unit (AR-152DR) or developer (AR-203DV) , otherwise print quality will suffer immediately.

Use this when the spanner/wrench light is solid or blinking. how to reset sharp ar-6020

To reset the developer counter (if you changed the developer):

Before diving into complex button sequences, try the most basic reset. This solves 90% of "freezing" or "unresponsive" issues.

When to use: The screen is frozen, buttons don't respond, or the machine is stuck on a processing loop.

Steps:

This is a hardware reset. It will not clear error counters, but it will reboot the CPU and clear temporary memory glitches. After approximately 60,000 copies, the AR-6020 will display

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.

Best for: Clearing persistent error codes (like "H4", "F2"), resetting the developer counter, or resetting the drum counter.

This is a more advanced reset used by technicians. Proceed with caution; changing settings in Simulation Mode can cause hardware issues if done incorrectly.

How to Enter Simulation Mode:

Common Reset Codes: Once in Simulation Mode, type the code and press Start:

The Sharp AR-6020 uses a developer unit (developer mix) that should last ~60,000 pages. Some online guides incorrectly advise resetting the developer counter when changing toner. Do not do this. Resetting the developer counter (Simulation 42) without replacing the developer powder will lead to light copies, backgrounding, and streaks.

If you have actually replaced the developer unit, you reset it via:

Before attempting any complex button sequences, perform a hard power reset. This clears temporary glitches in the machine’s RAM without erasing settings.

Steps:

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