The internal counter starts with a number of 0 and ends at 2000 for the black cartridge, or at 1000 for the other colors. The printer has an internal counter which is associated to the last read CRUM number. I have used the term expire because locked cartridges are not necessarily empty. This eeprom is costantly written by the printer during all its lifetime span, and it's permanently locked when it expires. Samsung clp-300 (the printer) track of the total number of the pages printed (referred as PAGES), it remembers other things as well, like the number of the print jobs (referred as JOBS) performed so far and the serial number of the toner cartridge (referred as CRUM number).Įach cartridge has a chip on it, which is basically a serial eeprom. Two aftermarket chips (aftermarket reset chips based on at34c02).Please refer to the very detailed schemes here: Chiprecharge Serial Programmer
My samsung clp 315 printer stopped working how to#
I2C eeprom programmer I will not describe how to build one on your own.Let's see how to cut the costs related to the chips with a permanent reset chip. The total refill cost is quite expensive, because you have to add to the toner powder ($6 per recharge) the reset chip ($7). Common reset chips are cheap (4-7 dollars each), but they should be replaced as soon as the toner inside the cartridge finishes. Now I will present herein a technique that permits to turn the vast majority of aftermarkets (non OEM chips) into permanent reset chips this means that you can turn a single chip into one that will last forever, since it will never expire. It's almost a year that I own this beautiful printer and it's some time right now that I know a couple of very interesting tricks to enjoy it even more.įirst of all Samsung just released clp-310 (and it's black version: the clp-315): for all the owners of the clp-300 unfortunately it means that they are planning to dismiss this printer, since the new toner cartridges for clp-315 and clp-310 are very different from the older ones for clp-300.
