why wont my printer print color pictures anymore? I cannot find the manual to my HP Officejet J5780. It prints emails okay, but not pictures. I went to color options on the printer page and it looks right as far as I can tell. How would I run a printer test page like the one it runs when I put in a new ink cartridge? I tried taking the cartridges out to prompt an alignment page, but it didn't do it.
