RESET SAMSUNG ML 1640 LASER PRINTER (easy reset)

Samsung ML 1640 Laser Printer cardrige not recognized after refill.?

My Samsung ML 1640 Laser Printer cardrige not recognized after refill. Its still showing as empty cartridge. i have a samsung ml-1640 with the original cartridge that came with the printer i have been looking at the chat on line about reseting the page count to 0 so it thinks the cartridge is full there is a way of shorting two pins on the chip in side the printer but i have tryed this and it will not work for me i think it is becouse this is a new one abou 6 month old brought around september 2009 there is all so a way of puting a new software version on so as every time the printer is turned off it resets to 100% ink i have tryed to do this and it did work once reset and i could use but it is still counting the pages and if i turn it off and on it will not reset.

in an etemt to reset back to page count 0 iflashed the same software i got that worked the first time agean in the hope it would reset to 100% ink but it will not work now ? i am not shure if i have the wright firmware for wat i need or maybe i have not put it on to the printer wright ?? this is where i got the software that worked the firt time and will not work now http://www.newerth.com/daemon/ML-1640_V1.01.00.66.zip if you can surgest where i have sliped up and even send me the wright firmware or link to the firmware with an idiots guide to sorting it out that would be good thanks rick .
