Here's my problem. I have an HP Officejet 6600 e-All-in-one. About two months ago it displayed that my magenta ink cartridge was low. I began hunting around for an ink cartridge and found a magenta one I hadn't thrown out. Wondering if it had at least enough ink to print out the document I was working on, I installed it. The printer said that the cartridge may be low on ink and asked if I was sure I wanted to install it. I said yes, and the system began checking the ink cartridge like it always does. It then threw up an error that my blue ink cartridge was defective. I reopened the cartridge door, removed the blue ink cartridge, and reinstalled it. The system now stated that not only the blue cartridge, but the yellow cartridge was defective now.
Annoyed, I logged onto HP's website and after half an hour of trying canned solutions, I called HP (who conveniently told me as I was calling them that my printer was out of warranty, I still called because they claim that ink cartridges are under a separate warranty). After waiting for a tech support rep, they had me clean the ink cartridge's connection head (most likely how it communicates with the printer to attempt to prevent refills) and remove and reinstall them half a dozen times. Finally, they stated that due to my printer being out of warranty, the only thing they can tell me to do is go buy new ink cartridges and try them. If they didn't work, they said, I would then, and only then, be sent a new printer. I was annoyed. Right on the side of my ink cartridge it claimed it was under warranty. I was then given a prepared speech in legalese that stated that essentially the ink cartridge warranty is worth less than a can of beans. At least the rep didn't make me pay for the call. I got the problem fixed by taking the cartridges up to Staples where I bought them (and the printer) and explained my problem. They gave me replacement cartridges which worked great.
I was told yesterday by my printer that my magenta cartridge was low. I went out and bought a brand new, genuine HP, replacement cartridge. After installing it, the printer claimed that my blue cartridge was defective. I have replaced every cartridge except my XL black one since the error last time. I am completely clueless as to what to do. I've Googled this error and heard tons of people's complaints about HP forcing high ink prices down people's throat with fancy lock-out systems. How can I get my printer to print without requiring me to replace ink cartridges I know are full?
tl;dr: Every time I replace an ink cartridge in my HP printer, it claims my other cartridges are defective. What can I do?
