unfortunately, buying two printheads is about the same as buying a new printer, which COMES with two printheads AND four in cartridges AND a whole printer! What gives? This is just one more way these printer companies rip you off.
the old adage applies: when your printer needs something, buy a new one. only problem is: they are putting less and less ink in the new printers. When you have to add ink, if you don't buy THEIR brand, your printer is guaranteed to start having problems--from "ink still empty" to preplace printheads to can't align properly to all kinds of irrelevant stuff that they simply put in, again, to rip off their users.
The Magnusen Act that says that using remanufactured ink cart's can no longer be used as an excuse for manf's to void the warranty has forced manf's to come up with new ways to simply make your printer FAIL (out of warranty) when you save a few bucks by using someone else's ink.
I NEVER had a problem with my hp UNTIL I used remanf. ink. And then, everything went wrong, including printhead warnings and printing and software problems--NONE of which had anything to do with the ink!!!
