Selecting stock for your Xerox Nuvera System

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.

Table 1-6. Paper weight ranges

Heavy weight	106 to 220 gsm uncoated
	140 to 220 gsm coated

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.

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.
