Reverse Engineering the Maintenance Cartridge - Part 1
Last week I wrote about dissecting my Canon printer's maintenance cartridge. I noted there was an I2C EEPROM sitting in there.My goal for the moment is to reverse engineer the contents of said ROM.I could go and solder some wires to the PCB, but that wouldn't be as good for reading an empty one (that I don't really want to destroy).So, how am I going to make a plug for this? Well, I have a 3D printer, don't I?A short bit of modeling and a few prints later I had a plug for the mystery connector!Perfect enough for my needs:Next up: a bit of Arduino coding to suck the data off the chip.
