Mike,
If you own a HP 2225x, you may face the same problem as I do: -the ink cartrige HP 51604 or 92261A produces poor quality prints because of a bad contact between the print head and the contacts on the flex cable. In my case, some copper lines are cut just near the little raised contacts(dimples). The cable itself (flexible circuit) is mainly fragile at this very spot due to mechanical forces when inserting & removing cartriges.
The good news is that this part is still available at HP !!! Contact you local HP dealer or Service center and ask for the following:
- Flex cable only, from logic board to Carriage : P/N 02225-80027 - Carriage assembly, includes Flex Cable : P/N 02225-60914
You should order preferably the entire carriage assembly, since it'll be easier to replace. Mouting the flex cable on the carriage can break the copper lines and give the same problem.
Happy servicing! If you want some more informations, let me know.
