The printer keeps an internal copy of the page count, so you need 2 permanent chips per cartrige, with 2 differnet serial numbers. With that chip and engaged hardware lock the printer can not write on the chip. At first, i solder new chips onto the tiny boards (Atmel 34c02 like the original) then i read about someone using similar chips but with a write protection pin. ![]() ![]() My problem was, the printer engages a writelock on the chip if the maximum capacity is reached, making it impossible to reset the chip. And wastes a lot of toner if i just replace the half empty cartrige. I used a simple LPT port interface and ponyprog software. I’ve done something very similar for years with my samsung clp-300 (color laser). ![]() Check out ’s page reset demo after the break. used a momentary switch, but given this is a once-every-few-months operation, a simple wire would suffice. The final hack that allows to reset the page count and used refilled toner cartridges is a simple wire that ties the SDA line of the EEPROM to ground on boot. Printing a configuration report, he was trilled to see that all page counts have been zeroed. When restarted the printer with the Bus Pirate attached, he noticed it took much longer to initialize. All the configuration settings and page counts for the printer are stored on an I2C EEPROM.Īfter 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 so he can use those third-party refill kits. 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. ![]()
