I recently was given an HP J3640 Officejet printer.

This printer uses 21 and 22 ink carts. To reset the carts, see
instructions at:

and many more. Refilling carts that have been empty for a long time
usually doesn't work well. I have various tricks for cleaning the
heads, but my batting average is about 50%. In the future, try to
refill before the cart runs completely dry.
