Hp deskjet 6940 paper jam
This past Saturday we just had a similiar problem on our church HP printer. Different number than yours, but most likely the same solution. It jammed when the last person used it, so they removed the crinkled paper. Or so they thought - there was a piece maybe 1-1/2" triangular shape stuck on top. I liked to never found it, I looked even with a flashlight 4 times before I caught just a hint of white way up there. If that is not it, there could be a door you have not opened. Most of them open top, back, front. Ours also opens on the side. The back opens in two places. Occasionally there can be a piece of paper you can only see from one door.
HP Deskjet 6940 not printing after replacing ink cartridge
My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected
Hp 6940 is not printing black
It sounds like a good chance the black has blocked it does not take much just things like leaving the cartridge out for a bit or it can also take a bit to get a new cartridge working.
I would recommend you try to do a head clean it uses a lot of ink doing this but sometimes there is no choice.
In settings you should be able to do only black option.
