Flip open the top of the ink cartridge holder of both the black and
color and look at the underside of the lids. There is a black spring
loaded plastic part that push the cartridge against the contacts.
There is a little part at the front that is easily broken. Compare
with the one on the color one to see if that's the case.

This model has a different carriage design and the above does not apply.

I would expect that a cartridge that has been in the printer for two years may
have an electrical issue; the cartridges are typically rated for six months
in-printer life. A new cartridge would probably solve the original posters
issue.
