We have used LG toner for models 4500, but severely damaged color - the color became dark, especially blue.

Black is even more difficult ... it we could not find for sale, used toner for older black and white models of printers HP, but in print appeared dirty gray spots and perhaps even need another toner for this printer, and tuck in the way the black cartridge is not managed, so that flow resource protection in the chip it to print. With color as something out, but the black will probably Nevertheless buy a new one.

The people who suggest something like reset CHIP.

Toner original, fell asleep, but the radish all just remember that it is a cartridge 0% and does not print.
