to the lead (left side) edge of the tray so it will bend easier as it
moves through the system. Load middleweight papers with the
grain in either direction. The weight ranges for the Xerox Nuvera
Production and Perfecting Systems are displayed in
Table 1-6.
Determining grain direction
One way to determine the grain is to fold a sheet of paper
lengthwise, then make a crosswise fold. Cross-grain folds tend to
be more rough and cracked as shown in
Figure 1-1.
Figure 1-1. Fold with and against grain
Another method you can use to determine the grain direction is to
tear a sheet. Paper always tears straighter with the grain.

You can also allow 4 inches (100 millimeters) of the short edge of
a sheet and 4 inches (100 millimeters) of the long edge of a sheet
hang over the edge of a table as seen in
Figure 1-3. The sheet
hangs lower (bends more) with the grain parallel to the table edge.
