Is there any way around this?\n\nThis is my roommate's all-in-one machine. She swears she replaced all her color cartridges not long ago and hardly used the printer at all since. She tried to print out something in just black and white today but the stupid thing said on the front read-out that the "depleted" yellow cartridge needs to be replaced in order to print out anything.\n\nIs the cartridge REALLY depleted or could the printer be lying?\nHow can one really tell how much ink is actually in a cartridge when the [SIZE=3]integrity of the machine's 'depleted" message is is in question? They don't put sight windows [/SIZE]on cartridges.\n\nCould the cartridge really be empty though it has hardly ever been used since new?\nIs it possible to get jipped at the factory by the cartridge maker, HP?\n\nI just did an interesting experiment with my Deskjet 1520. I pulled out the combination color cartridge (has all three colors, red, yellow and blue, in a single unit) and it still can print in black and white only.\n\nMy roomie's 6600 has three separate color cartridges and one black cartridge.\n\nWhat is recommended?\nRepair printer in shop?\nGet a new machine?\nReplace cartridge and if it still acts the same way, return the cartridge for her money back?\n\nHow can this be diagnosed cheaply?
