Automatic RICOH FM24C02B Printer Toner Chip Resetter

cults3d

Done this a while ago, in 2017. Finally was able to get all files together and share my project. Hope this helps! Made it to automatically detect, which chip is present and reset it. Simple arduino sketch. All files are included. I had the RICOH SP 250 SF, but it's compatible with any FM24C02B eeprom based toner. Probes: I used these cheap china push pin probes. https://www.ebay.de/itm/193735481644 LEDs: For indication I used some generic 3mm LEDs. MCU: For controlling and serial output I used an cheap Arduino Nano clone. Useful links: - https://stefansbb.blogspot.com/2016/04/hacking-ricoh-sp-c250dn-toner-cartridges.html
