How do you install a new cartridge in a printer?

For the HP printer, after you print out the alignment page, you'll see a picture of a printer on the bottom left hand corner of the alignment page.

For reference purposes, take the RIGHT BOTTOM corner (OPPOSITE of the printer picture). THIS corner should be the corner closest to you on the glass.

In other Words, when the print side is down on glass, (and properly positioned with the page touching the front right corner), now the printer picture will be facing the right bottom corner if you did it correctly.

I hope this helps because you can go crazy!
