I don't know how to load the paper into an HP Officejet J4580

The paper is loaded into the tray that is centered at the bottom if the front of the printer.
To load paper into the tray you need to:

• Push the paper guide on the left all the way out - to the left.
• Place a stack of paper into the tray and alight the paper to the right bar and the back. The paper should be placed into so that the print side is down.
• Slide the paper guide to the right till it's aligned with the paper.
