I have a couple of Canon 4-cartidge printers, a S400 and a BJC-3000. On the BJC-3000, it will not print black. There is black ink in the cartridge, and the other colors print OK.
Rather than spend $57 (CompUSA price) for a BJ-33, which contains a new printhead and 4 cartidges, I would like to attempt to somehow clear the printhead of whatever is blocking it.
Any suggestions on how to do this without totally screwing up the cartidge?
Just a note: The printer was $7 at a local thrift store. It would not feed paper, but I found the cause of that - a leaf in the paper input tray. I know that you can get new printers for $40 or so, but they use 2 cartidges - color and black which are about $30-40 each. On these Canon printers, individual color carts are between $10 and $14.
