Ricoh Aficio SP C250/260/261 Toner Cartridge Chip Reset

This sketch using ATmega328P(Arduino Uno/Nano) to read/write Ricoh Aficio SP C250/260/261 toner cartridge chip(24C02) with I2C communication.

This toner cartridge used in

• Ricoh SP C250DN
• Ricoh SP C250SF
• Ricoh SP C260DNw
• Ricoh SP C260SFNw
• Ricoh SP C261DNw
• Ricoh SP C261SFNw

Features

• Set toner to full. (chip reset)
• Set toner to empty. (may useless)
• Selectable. (each toner cartridge, all present toner cartridge)
• Write custom data. (1 to 128 bytes, but can not use with all present toner cartridge.)

Usage

1. Open sketch in Arduino IDE.
2. To write custom data, add your data to variable shown below. If just want to do a chip reset, skip this step.

const byte CUSTOM_DATA[] = {168,0,1,...};

3. Upload sketch to your board.
4. Following the instruction shown in serial monitor.

Options

Operation

• f - set to full
• e - set to empty
• c - write custom data

Target

• c - cyan
• m - magenta
• y - yellow
• k - black
• a - all present toner cartridge (can not use with custom data)

Note: Each entry will appear only when detected.

I2C Addresses

Toner	Addresses(DEC - HEX)
K - black	83 - 0x53
C - cyan	82 - 0x52
M - magenta	81 - 0x51
Y - yellow	80 - 0x50
