Epson, what a rip off. Obviously I regularly buys cartridges, because we are obliged to do it, but it really is a scam! After a set number of copies, the printer (Epson-600 xp) stops working until you change the cartridge, even if ink remains in the cartridge. And if the yellow cartridge is empty, you can not possibly print in black and white before replacing the cartridge: it is unbearable!
and I feel that one is not 500 copies with a cartridge (I'm almost on the same!)
