This is a new old stock Ink Cart housing for an HP Designjet 9000s or a Seiko Colorpainter 64S
It holds the 3 color ink carts shown by the colored labels in picture #7 and is mounted (on your own printer) under one end of the printer. This housing includes the door assembly with it's sensor (pictures 2,3, and 4) and the ink cat sensor's long skinny P.C. board mounted on the back end (pictures 5 and 6) It does not include any other internal parts (see picture #7) You will need to transfer over those other missing parts from your own printer......If you don't see it in these seven pictures, it is not included with this auction. If you have damaged or bent your own ink cart housing, this one might help you get your printer running again.
