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.

Are you currently seeing a specific error code on the display that you need help troubleshooting?
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.
It started with a blinking orange light—the dreaded "System Error." Elias, the junior office manager whose job description seemingly included "Machine Whisperer," stood before the silent beast. The display was cryptic, and the usual button-mashing rituals had failed. The office was grinding to a halt.
"It needs a hard reset," Elias muttered, pulling out his tablet. He didn't just need a quick fix; he needed to perform the digital equivalent of open-heart surgery on the AR-6020’s firmware. Chapter 1: The Secret Entrance
Elias knew that standard menus wouldn't save him. To fix a Sharp AR-6020, you had to enter the Simulation Mode. This was the "developer’s basement" of the machine.
With the precision of a safe-cracker, Elias performed the sequence: He pressed the # (Hash) key.
He pressed the Interrupt key (the one with the symbol of a circle with a diamond). He pressed the C (Clear) key. He pressed the Interrupt key once more.
The lights on the panel flickered, and the display went blank for a heartbeat before showing a prompt for a code. He was in. Chapter 2: The Maintenance Purge
The machine was stuck in a "Maintenance Required" loop. Even though the rollers were clean, the internal counter was convinced it was dying. Elias needed to reset the maintenance cycle.
He typed 24 on the keypad and hit the Start (Print) button. The sub-menu flickered to life. He then entered 07—the specific sub-code for the maintenance counter.
"Are you sure?" the machine seemed to ask with its blinking cursor. Elias hit Start. The numbers on the screen plummeted back to zero. A small victory, but the orange error light remained. Chapter 3: The Developer’s Ghost
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.
He backed out to the main prompt and entered 14. This was the "Clear All Trouble" command. It was the "nuclear option" for errors that didn't go away with a simple power cycle. He pressed Start, and the machine let out a long, low whirring sound—the sound of a brain being scrubbed clean. Chapter 4: The Rebirth
To finalize the ritual, Elias didn't just flip the switch. He exited Simulation Mode by pressing the CA (Clear All) key several times until the screen returned to its default "Ready to Copy" state. Then, for good measure, he performed the physical reset: He switched off the main power on the side of the machine.
He unplugged the cord, counting to thirty to let the capacitors drain. He plugged it back in and flipped the switch.
The AR-6020 groaned. The scanner light swept across the glass like a waking eye. The internal rollers spun, testing their grip. Finally, the orange light vanished, replaced by a steady, confident green.
Elias hit the "Copy" button. A single sheet of paper slid out, warm and crisp, bearing the perfect image of a test pattern. The pulse of the office returned, and Elias, the Machine Whisperer, returned to his desk in triumph.
