Imprima até que o pó do toner acabe completamente, aproveitando o cartucho até a última gota. Cuidados Importantes e Riscos Antes de Começar

| LED Pattern | Meaning | Reset Solution | | :--- | :--- | :--- | | | Toner empty | Method 1 or 3 | | Red blinking slowly | Paper jam | Open covers, remove paper | | Red blinking fast | Fuser error | Unplug 1 hour, then factory reset | | All LEDs flash | General hardware fault | Method 4 (factory reset) | | No lights | Power supply dead | Check fuse, power cable |

If the button sequence fails, the printer’s EEPROM (memory chip) may be locked. You can try a software command.

As a last resort for a separate "won't power on" issue he’d read about, some brave souls even replaced a on the circuit board, saving their printers from the landfill for the price of a candy bar.

Note: Ensure your antivirus software is temporarily disabled, as generic firmware modification tools are frequently flagged as false positives. Step 3: Step-by-Step Reset Procedure

Samsung did not provide deep reset software for macOS. Use Method 1 or Method 3.

A realização do é a solução definitiva para esse problema. Este procedimento modifica o software interno da impressora para que ela ignore o chip do toner, permitindo que você recarregue o mesmo cartucho várias vezes ou utilize modelos compatíveis muito mais baratos. O que é o Reset de Firmware e Como Ele Funciona?

O arquivo de reset deve ser estritamente compatível com a versão atual do firmware da sua impressora (ex: V1.01.00.18, V1.01.00.19, etc.) e com o número de série (CRUM) do equipamento. Arquivos genéricos podem inutilizar o aparelho. Passo a Passo para Realizar o Reset Passo 1: Identificar a Versão do Firmware e o Serial/CRUM

Samsung printers use a "reset chip" on toner cartridges that counts pages; once a limit is reached, the printer may stop functioning even if the toner isn't actually empty.

The necessity of a reset stems from how these printers track toner usage. Unlike more sophisticated office printers that use optical sensors to detect actual toner levels, the ML-1860 series relies on a simple chip on the toner cartridge that counts pages or drum rotations. Once a predetermined threshold is reached—typically around 1,500 pages—the printer refuses to print, flashing an error light even if the cartridge still contains enough toner for hundreds more pages. For users who refill cartridges with third-party toner, or who print low-coverage text, this artificial “empty” signal is a barrier to economical printing. Resetting the printer overrides this counter, allowing the machine to continue functioning until the physical toner is genuinely exhausted.

If you encounter issues during or after the reset process:

If your printer is unresponsive, stuck on a logo, or displaying persistent error lights (like a blinking red light), a standard power reset often clears temporary memory glitches. JustAnswer Turn off your computer and the printer. Unplug the printer from the power source. Wait at least 1 to 5 minutes

Drag the .fls (firmware) file onto the usbprn2.exe application while the printer is connected via USB.
