samsung ml 1666 toner resetter

This device is designed to reset the toner used in the Samsung ML-1666 laser printer. It is based on the PIC-16F73 microcontroller, which is readily available and inexpensive in Bangladesh, with a cost of approximately 90 taka each. The total cost to assemble this device is estimated to be between 200 to 250 taka, and it is relatively easy to construct.

The toner reset circuit for the Samsung ML-1666 utilizes the PIC-16F73 microcontroller, which features 18 pins and offers a variety of functionalities suitable for controlling the reset process. The circuit is designed to interface with the printer's toner cartridge, allowing the user to reset the toner count and restore the printer to operational status after a toner replacement.

The schematic includes the following key components:

1. **Microcontroller (PIC-16F73)**: Central component that processes the reset command. It is programmed to communicate with the printer's circuitry to reset the toner counter.

2. **Power Supply**: The circuit requires a stable power source, typically 5V, which can be supplied via a USB connection or a dedicated power adapter. Proper voltage regulation is essential to ensure the microcontroller operates correctly.

3. **Resistors and Capacitors**: These passive components are included for signal conditioning and stabilization, ensuring that the microcontroller receives clean signals for processing.

4. **Transistor or Relay**: Depending on the design, a transistor or relay may be used to switch the reset signal to the toner cartridge. This component acts as an interface between the microcontroller and the printer's circuitry.

5. **Programming Interface**: A means to program the PIC-16F73 is necessary, typically involving a programmer that connects to the microcontroller's pins. This allows the user to upload the firmware that contains the reset logic.

6. **PCB Layout**: A printed circuit board (PCB) is recommended for mounting the components securely and ensuring reliable electrical connections. The layout should be designed to minimize noise and interference, enhancing the performance of the reset function.

The assembly process involves soldering the components onto the PCB, ensuring correct orientation and connections as per the schematic. After assembly, the device can be tested with the Samsung ML-1666 printer to confirm that the toner reset function operates as intended. Proper testing will help to validate the functionality and reliability of the device before regular use.

This toner reset device is an economical solution for users of the Samsung ML-1666 printer, enabling them to extend the life of their toner cartridges and reduce waste.This is to reset the toner used in Samsung ML-1666 laser printer. Based on PIC-16F73. This chip is available in Bangladesh and cheap. I bought few at taka 90 each, probably last month. So it would cost you maximum tk 200 to 250 to build one. And also easy to make. Bellow you would find.. 🔗 External reference
