I'm having trouble with my HP PSC 2510 Photosmart (printer, fax, scanner, copier). I don't know what started it, but recently the printer printer button stays a solid green, and the fax and scan buttons flash green. When I turn the printer on, it says "Align Print Cartidges" and below that says "Press OK to print Align Page." When I press OK, it will go through it's gear up and start to feed the page then stop, beep, and say "Out of paper" even though the paper tray is full. After that I press OK and then it beeps and says "Paper jam." If I press OK again the page will print, but I don't want to have to do that every time I want to print something.
Please help.
