HP Cartridge Installation Error

[A.K.]

I've been unable to print even B/W text with my HP Deskjet 940c for
some time, and the status light is blinking to indicate an installation
problem with the color cartridge (rather than just an empty cartridge,
although it probably *is* empty). I've tried unplugging and replugging
the printer, wiping off the copper contacts, firmly reseating, etc.
Because it used to work, I assume the cartridge itself isn't defective.
I'm trying to gauge whether it's worth gambling $35 for a replacement
cartridge if it turns out that the problem is something else and the
printer will have to be replaced anyway. (I'm reluctant to do that
unless it's necessary, as I described in another post, because it's
hard to find a model that will be economical over time given that our
usage is low, we don't print much in color, and we never print photos.)


Any ideas about whether a replacement color cartridge is likely to
work?

If the cartridge is very old it may have failed electrically, and is the
most likely cause of your problem.

Most likely a fresh cartridge would solve your problem.

Most current DeskJet models will work with a single cartridge (either
color or black) if one of the cartridges fails.

Thanks. I'm going to gamble $35 that you're right.
