TONER FOR RICOH SP C250DN FULL
With that done I copied the data from a fresh full cartridge to a "empty" one inserted it into the printer and a huge smile took hold. This item: (1 time) 4 Toner Refill for Ricoh Aficio SP C250SF, SP C250DN Color Printer + 4 Reset Chips by New Era Toner 38.00 TM-toner 4 color toner reset chips for Ricoh Aficio SP C250SF, SP C250DN SPC250SF SPC250DN refill 407539 407540 407541 407542 12.

But after reading a fresh cartridge back I got a different but consistent result.
TONER FOR RICOH SP C250DN CODE
I really wasn't sure my code was working properly because the result was just a huge mess. Nice! Next thing was reading back the eeprom. And I was right after increasing the search radius I finally got a response on 0xA7. So I thought maybe these ICs don't use the standard address space. Changing the pullup also hasn't affected the result in any way. So I slowed it down really hard but still got nothing. The pad closest to the edge is GND, followed by VCC, DATA, and Clock.
The chip is near one edge of the cartridge.
You will need to have the 4 files below in the same directory: 'black' 'cyan' 'magenta' and 'yellow'. So maybe I was simply to fast for the IC while sweeping across the addresses. Below are single-line commands to run in BASH on a Raspberry Pi to rewrite the toner chips to 'full' for a Ricoh SP C250DN Printer. A quick check was made to verify the cartridge was still working.
