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. First 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. 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. Common reset chips are cheap (4-7 dollars each), but they should be replaced as soon as the toner inside the cartridge finishes.

The total refill cost is quite expensive, because you have to add to the toner powder ($6 per recharge) the reset chip ($7). Let's see how to cut the costs related to the chips with a permanent reset chip. To accomplish this task, you will need: • I2C eeprom programmer; I will not describe how to build one on your own. Please refer to the very detailed schemes here: • software or similar one • Two aftermarket chips (aftermarket reset chips based on ) • Basic soldering skills The Lock Protection 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). Each cartridge has a chip on it, which is basically a serial eeprom. This eeprom is costantly written by the printer during all its lifetime span, and it's permanently locked when it expires. I have used the term expire because locked cartridges are not necessarily empty.

The printer has an internal counter which is associated to the last read CRUM number. 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 counter is increased by 1 for every printed page; when the counter reaches i.e.

'2000', the chip on the toner is marked as empty and permanently locked. This is an awesome blog. My gratitude for contributing so much time to it. I think it would be great to provide multiple blogs for the CLP 300 series including cleaning the imaging unit, alternative sources for toner, chips, as well as other maintenance problems and solutions. I am not a programmer, but from the first printout I see that the pages address changes from new to used to locked. Is it possible that this register is read and when it hits a 'max' value, the printer then locks the chip. If this is so then swapping cartridges would not foil the locking.

I would be interested in obtaining permanent reset chips. Anonymous @Anonymous Connect PIN 5 to the ground of a USB plug. USB has 4 connections: 5v, Data, Data, Ground Connect right side of Z1 to ground Connect Right side of Z2 to ground Pin 1,2,3 are NOT used. Pin 7 is connected to the resistor and the resistor is connected to the left side of the diode. @karen Karen, I'm sorry but I'm just trying to help CLP300 users like me: it's not a business driven activity. You can buy resetters from various chinese companies (I do not provide the link since I didn't test it personally).

Anonymous Hello everyone, I would like to tell about my problem and how did I solve it. I ordered 4 chips from China. Once the Cyan was out of life, I have changed the chip on Cyan and it worked just fine.

Then after some time - Yellow cartridge ran out, so I also changed the chip on it. But after changing the chip, suddenly all the other colours stopped working. Printer panel was saying, that Cyan, Magenta, Black and Imaging Unit were invalid. Only Yellow cartridge was valid. I tried to figure out what was wrong. I took an Arduino and wrote some software to dump the contents of eeproms.

There seemed to be no problems with them. I tried rewriting them with a lot of different combinations found on the internet. Spent almost full day trying to figure out what was wrong, and next day I tried one last combination. I thought if I rewrite all the chips at once, maybe it would work. And one time, only by coincidence, I reflashed Cyan chip, then took Yellow chip and forgot to change the I2C device address in software - BUT IT STILL DID RESPOND. While it should only respond to address 0x50, it respond to 0x51, 0x52 and all other addresses. Drivers Hp Scanjet 3970 Windows 8.
