A:AnswerHi there! I'm sorry to hear about your printer complications. I recommend taking a look at this support document from HP to assist you: https://support.hp.com/ie-en/document/c05547613
A:AnswerYou probably just installed them wrong, I put mine in and never had a problem, it does happen from time to time, but I would just try it again. Look at the little picture description and insert them exactly as pictured.
A:AnswerYou are not required to enroll in Instant Ink, or in Best Buy's Easy Replenish, though both are phenomenal options to help you save on ink costs!
A:AnswerNo, the printer automatically adjusts/sets ink levels. You can try adjusting the photos prior to printing, using selected HP photo papers and 1200 input dpi.
