Install the paper separator and pull out the paper guide as shown in Figure 1-11 . Fit the notches in the bottom corners of the separator over the pins at the front of the paper slot. The separator keeps the paper that is coming out of the printer from being pulled back in. Pull out the paper guide at the back of the printer. This guide helps keep the incom- ing paper from catching on the printer cable. Figure 1-11.
