Samsung clp-300 toner chip problem

Hi,everybody, as my printer started to flash red on the cyan toner, i decided to buy cheaper ones directly from china. After 3 weeks they finally came and i put the cyan toner in. But my computer told me that it was an invalid toner. I tried many things,from changing the chip to connecting the upper left pin on the chip from the motherboard, to the ground and then turning it on.I even changed the firmware. Nothing worked. So after 3 hours on the internet i didn&find a solution that would suit me,so i read in some forums about reseting the chip on the toner-too hard for a newbie.Finally i came by a reply from a Samsung CLP-315 Page Count Reset Hack that helped me a lot. The solution was to put some tape over the chip. The printer will stil be flashing red, but the page will print even with the old toner inside. So,no printer disassembly required , no chip needs resetting. I hope this video helped you, as the solution helped me.
