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 how to reset the Sharp AR-6020 is essential.
This guide will walk you through every type of reset: from a simple soft reset to clearing maintenance counters, fixing error codes, and performing a factory reset. Warning: Some resets require entering service modes. Use these carefully, as altering the wrong setting can affect print quality.
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.
The Sharp AR-6020 has a hidden "Simulation Mode" (accessed via # → * → C → * on some models). Use this only for diagnostics, not casual resets. For everyday use, the toner and maintenance resets above will keep your machine running for years without a technician.
