Hi Callen,

You can try an Ink System Reset. To do this:

Remove all ink cartridges, Close the Carriage Access Door.

Unplug the power cord directly from the back of the printer.Unplug the other end of the cord from the power source.If the power cord had a power module, unplug and replug it.

After 60 seconds, plug the power cord directly into a wall outlet ( not a surge protector or battery backup ).

Plug the cord into the back of the printer. When the printer powers up and asks for ink cartridges, install them one at a time. Open the access door, put the back of the ink cartridge in, press the front of the cartridge down until you here it snap, close the access door long enough for the cartridge to register. Open the door and repeat the process until all inks are installed.
