The original ink cartridges for the hp 6970 are the 904 ink series. There is not 904 ink series available anywhere.
I boughtr the 902 ink series because are recommended by Amazon for the hp 6970, but the machine does'nt accept the cartridges, you can insert them but the machine enter in a lock. The machine also warns you of innapropriate ink inserted.
Can you recommend a ink series that appropriate work with my machine?
