I get the "Incompatible Print Cartridge" message every time I turn on my printer. I have cleaned the "dots" with filtered water, unplugged the usb cord, etc. Nothing works. The power button flashes continually and I cannot access any of the features. For a while, it would work intermittently but not anymore. This problem began the last time I installed a black ink cartridge, and yes, it is the correct cartridge. I've had this printer for years.
