Any computer geeks here that can help me out on something related to a printer?

I just received a reconditioned black ink cartridge for my HP Deskjet 840C. Removed the plastic tab, peeled off the tape and installed. The printer still won't print and the indicator lights seems to indicate it still thinks it's out of ink. There is also a tri-color cartridge which feels empty but I don't use any color with this printer and I don't believe it's been an issue before but could be wrong.

Could the fact that tricolor cartridge may be empty cause the printer to not want to engage?

I've tried several things such as turning the printer on and off, checking connections, etc etc. to no avail.

My computer geek is in Germany for a month with students and I can't reach her at the moment.

Thoughts?

I originally was set to buy both cartridges locally but the Walmart wanted over $70.00 for both and I didn't think I needed both. So I got two of the black ones for about $8.00 reconditioned on Ebay.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
