OfficeJet 7740 Ink Cartridge not Compatible

[slachney1]

I purchased this printer a few months ago and it has been fine. When I purchased it, I immediately wanted to buy another set of ink so that when the included cartridges ran out, I would have some on hand. Although inside the printer door it says to use 954 cartridges, those do not seem to be available anywhere, so I went on HP's site to find compatible cartridges. HP said to use 952, so that is what I bought. 

Today, my black ink ran out, so I replaced it with a 952 cartridge. The printer had an error message which said "The indicated cartridges are not intended for use in this printer." 

I spent an hour online chatting with tech support who determined something must be wrong with the cartridge and they would send me a replacement. It will be delivered on December 30, and while I am grateful for the replacement, this does not help me print TODAY or for the next 18 days.

I went to Office Depot and purchased another 952 black cartridge to use in the meantime. Same message. I removed all cartridges, turned off the printer, unplugged the printer, turned the printer back on, installed all new cartridges and got the same message again.

What is going on? If the 952 cartridges are not compatible with the 7740, why aren't the 954 cartridges available?
