How To Reset Sharp Ar-6020 [patched] May 2026

In the quiet, hum-drum heart of the "Ever-Ready Logistics" office, the Sharp AR-6020 was more than a printer; it was the rhythmic pulse of the company. It sat in the corner like a stoic monolith, churning out invoices and shipping manifests with a mechanical reliability that everyone took for granted. Until the Tuesday of the Great Stall.

Once successful, the red "Drum" indicator light should turn off.

Note: If this option is grayed out or unavailable, the machine may require a "Simulation Mode" reset (see section 3).

This resets the Non-Volatile RAM (NVRAM) back to factory default.

  1. Turn off the machine using the main power switch (usually on the left side or back).
  2. Wait 10 seconds.
  3. Turn it back on while holding # (the asterisk or hash key depending on the region) or press C (Clear) + P (Pause) together quickly. If that fails, proceed to the sequence below:
  4. Press: # → * → C → * → P (in quick succession) to enter simulation mode.
  5. Use the numeric keypad to enter 16.
  6. Press the Start (Copy) button.
  7. The display will show a code. Press Start again to execute simulation 16-01 (Toner/Developer auto adjustment).
  8. Wait 2-3 minutes for the machine to run, then turn the power off and on.

The real culprit was likely the developer unit or a fuser error (often signaled by an H4 or L6 code). To clear these deep-system "trouble codes," Elias stayed within Simulation Mode.

After about 5 seconds, John released the [Clear] and [CA] buttons. The display screen flickered, and the machine emitted a series of beeps. He then pressed the [Start] button, and the machine began to reset.
