Dell A940 printer problem both in printing and copying using the black cartridge.?

Question

Cannot print with the black cartridge. If I try to copy by pressing BLACK button, nothing is printed. But, if I copy by pressing the COLOR button, it is printed in black. I tried to Clean the cartridge but no black lines were printed. However, when I use the Align option, a black line is printed.

Tried two black cartridges and get the same results.

What might be tried to resolve this?

Hi. Sounds like the signal is not getting to the black cartridge, Usually there is a ribbon cable that connects the printer head to the data source and these can wiggle free over time. I Would GENTLY grab the ribbon near the ends and pull them out just a little and re-seat them. Good Luck!
