7. Align the four corners of the paper stack and insert the paper (print side up) under the tab.
Look
Do not use paper that is folded, creased, or heavily warped. Make sure that all the paper is under the tab.
Do not overload the paper tray.
8. Align the side guides with the edges of the paper.
Look
Pushing the paper guides too hard against the edges of the paper stack can cause a paper jam. However, if the paper guides are too loose, the paper may twist as it feeds through the printer.
9. Hold the paper tray with both hands, align it with the opening in the printer and gently insert it.
10. Push the paper tray completely back into the printer.
Look
Do NOT use excessive force on the paper tray. Doing so could damage the paper tray or the inside of the printer.
