5) Align the four corners of the paper stack and insert the paper (print side up) under
the tab.
Note:
Do not use paper that is folded, creased, or heavily warped.
Do not overload the paper tray.
6) Make sure that the side guides are aligned with the edges of the paper.
Note:
Pushing the paper guides too hard against the edges of the paper stack can cause
a paper jam. However, if the paper guide is too loose, the paper may twist as it
feeds through the printer.
7) Hold the paper tray with both hands, align it with the opening in the printer and
gently insert it.
