If after performing these resets your Sharp AR-6020 still displays an error, the hardware component itself is faulty. Common failures include the thermistor (H3/H4), the main motor (L3), or the paper feed clutch (J3 repeats). At that point, contact a Sharp authorized technician.
| After Reset Code | You Must Replace | Part Number (Example) | | :--- | :--- | :--- | | SIM 24 (Drum) | Drum cartridge, Blade, Grid, Main charger | Sharp AR-201DR | | SIM 42 (Developer) | Developer powder (Magnet roller base) | Sharp AR-201DV | | SIM 14 (H2-H6) | Thermistor, Heat roller, Fuser lamp | Sharp AR-201FT |
Performing a reset on a Sharp AR-6020 should be done carefully. Some resets (specifically simulation 24 and 42) zero out critical counters. Do not perform these unless you have physically replaced the corresponding maintenance parts (drum, developer, fuser). Part 1: The Simple Soft Reset (No Codes) Before diving into complex button sequences, try the most basic reset. This solves 90% of "freezing" or "unresponsive" issues. how to reset sharp ar-6020
| Error Code | Meaning | Reset Method | | :--- | :--- | :--- | | | EEPROM error | SIM 16 (Clear EEPROM) | | F1 | Toner motor error | SIM 14 (Cancel) + replace toner cartridge | | F2 | Toner density sensor error | SIM 25-02 (Manual adjustment) | | F5 | Communication error (scanner) | SIM 14 + reseat flat cables | | L1 | Mirror motor lock | SIM 14 + lubricate scanner rail | | L3 | Main motor lock | SIM 14 + check drum rotation | | CH | Please add toner / Door open | Replace toner or close front cover properly | | EE | EEPROM write error | SIM 16 (Reset NVRAM) |
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. If after performing these resets your Sharp AR-6020
This resets the Non-Volatile RAM (NVRAM) back to factory default.
The Sharp AR-6020 is a workhorse in many small to medium-sized offices. Known for its durability and low cost per copy, it handles high volumes of printing, copying, and scanning. However, like all office equipment, it will eventually display error codes, maintenance reminders, or simply freeze up. | After Reset Code | You Must Replace
Resetting the counter without replacing the drum/developer will lead to poor print quality (gray background, black spots, or faint text). How to enter Simulation Mode (Admin Reset) To reset the maintenance counters, you need to enter "Simulation Mode" (service mode).
