Hello. I have an HP Deskjet F4480 that first stopped printing black so I changed the cartridge since it was getting low, but still no printing black. It was printing a little color but it was getting low so I changed that cartridge, but now I'm not getting any color either. Basically my test pages are blank.
I also remember in the past after changing a cartridge that an alignment process or something happened automatically. I'm not sure that is taking place.
Anyone have any suggestions or know what might be going on here?
Thanks!
