Cartridge iinstallation - Tony Guggino - 10-08-2004
I replaced the black cartridge in the HP 720c and the yellow cartridge light keeps blinking and the printer doesn't work. I've removed both the black and color cartridges but that didn't solve the problem.Please let me know to correct this problem
