I bought a Hp Officejet L7680 and after a good run of about 1 yr it indicated the black and yellow printhead needed to be replaced. I bought one thru LD at a good price and in less than 2 months the printer indicated again that the B/Y printhead needed to be replaced but now because of failure.
At $[...] a pop I wasnt going to throw good money after bad. So I bought a refurbed L7780 that has alot of parts in common and ran it for less than 2 months and the gal darned B/Y printhead was havin fits printing in dark black.
I tried everything and with a loss of trust in the product decided Id wait until the 3 month manufacturer warranty ran out because Tiger would then allow a full exchange value on another item.
Before giving it up completely I used a standard refill kit from a previously owned Hp. In it is a print head cleaner that is applied through a syringe. Well gooollleeee jeez! 2 printers later I found that the ink cartidge inlets and/or the electrical contacts bounce back after a cleaning. I now have 2 perfectly well running printers.
You can buy a cleaner for less than 20 bucks. Try it and save yourself alot of grief.Get more detail about HP Officejet Pro L7780 Color All-in-One Printer/Fax/Scanner/Copier (C8192A#ABA).
