Printer cartridge This is my 4th. request. I have been using a "HP" color cartridge in my printer (5740) for over 6 mo. Now it tells me I have the wrong cartridge installed. The cartridge is half full of ink. However the Black ink HP cartridge still works & will print as long as I take out the color cartridge first. Please help??? Thanks.

Re: printer cartridge

Well, Since the cartrigde has been working it could be just a matter of contact. Try removing the cartridge, and clean the contact surface on the cartridge with a alcoholic based cleaning liquid on a soft cloth. Tis might help solve the problem.

If the ink cartridges are loaded, when you choose File Print, go into the properties and indicate you would like to print in color. Or you can go to the Printer from Start, Printers & Faxes or it may be under Control Panel.
