Reset Impressora — Samsung Laser Ml 1860 1865 1867

Samsung (now owned by HP) engineered these printers with a memory chip on the toner cartridge. This chip tracks two things:

Once the counter hits the limit, the printer stops and displays a red blinking light (usually the middle LED) or a computer message saying “Toner Empty” or “Replace Toner.” However, many users refill their cartridges with toner powder. Because the chip still says “empty,” the printer refuses to work. Resetting forces the printer to ignore the old counter.

Warning: There are two types of reset. A “soft reset” clears temporary errors. A “hard reset” (or chip reset) makes the printer think the cartridge is brand new. This guide focuses on the latter. Reset Impressora Samsung Laser ML 1860 1865 1867

To understand the reset procedure, one must understand the communication protocol between the printer engine and the consumable.

2.1 The Toner Chip Mechanism Original Equipment Manufacturer (OEM) toner cartridges for the ML-1860 series are equipped with a small Integrated Circuit (IC) chip mounted on the cartridge casing. This chip does not measure toner levels physically (via optical sensors or weight); rather, it acts as a non-volatile memory storage. The printer writes data to this chip incrementing a count with every page printed. Samsung (now owned by HP) engineered these printers

2.2 Regional Firmware Variations The ML-1860 series is often segregated by region (e.g., ML-1860 for Europe/Asia, ML-1865 for Latin America). While the hardware architecture is identical, the firmware locks the device to specific region-coded cartridges. Therefore, a reset solution must account for the specific model number to ensure firmware compatibility.

If your printer is behaving erratically (paper jams, all LEDs flashing, ignoring commands), you need a factory reset. This clears the memory, not the toner count. Once the counter hits the limit, the printer
