I am having the HP Officejet 6210 All in One printer at my place. I am having the problem with the Cartridge of the HP Officejet 6210 All in One printer. The error which i am getting with this printer while trying to take out the printouts is that "incompatible Cartridge installed". I have tried to solve this problem by my self but not succeeded. This problem started after i installed the new one after the original finished. What can i do to solve this problem of the HP Officejet 6210 All in One printer?
