After dumping the data held on this EEPROM with an Arduino and sniffing everything going into the EEPROM with a Bus Pirate, was nearly at his wit’s end.
Luckily, figured out a dead simple way to reset the page count so he can use those third-party refill kits.Īll the configuration settings and page counts for the printer are stored on an I2C EEPROM. The printer sends out the ‘low toner’ warning based on page count and won’t print if the page count is too high, negating the economy of a toner refill kit. A full set of toner cartridges sell for about the same price as the printer itself, so figured he could simply refill the toner in the cartridges he already has. Really liked his Samsung color laser printer right up until it was time to replace the toner cartridges.
