Printer cartridge appears to be blocked

Hi all,

Hope you can help me with this one. We have a HP Photosmart 1215 printer. We have just put a BRAND NEW colour cartridge into the printer and it appears to be blocked, as no ink is flowing. Its expiry date was in July, so it is probably our fault. However, does anyone know a way of getting the ink to flow again.

Thanks in advance
Chriso

Clean all the contacts on the cart and in the printer, and re-seat the cart a few times in it’s carraige. If the cart is printing nothing at all, it’s likely defective. But you can try soaking the head in hot water with a bit of ammonia.

I just got a new one and it works, must have been defective, but I’ll give it a soak and see what happens (what have I got to lose).

Thanks
Chriso

EDIT: Well, I had no ammonia, but warm water had no effect.

Thanks for trying
Chriso
