Recognition Problem?

Check if the parts of cartridge are damaged, especially the actuators or locating tab. Or check if the chip has some scratch. If the chip is not in proper position at the cartridge recess portion, then try to pry the chip and reposition. If the chip still fails then use a replacement chip to verify if the problem is solved. Or check the internet (OEM web) whether the printer or chip has different distribution for districts.
