Dynamic Paper Tension Adjustment
This procedure helps you identify and eliminate conditions that contribute to
paper jams, excessive tension on the paper feed motor, and vertical dot
compression or expansion.
1. Open the printer cover.
2. Unload paper.
3. Unlock both tractors and move them outward to the sides as far as they
will go.
4. Prepare a length of 14 inch wide paper consisting of three sheets that are
still attached at the perforations. The paper must be single part, 18 lb.
maximum weight, 0.0036 inch (0.09 mm) maximum thickness.
Open the
cabinet front door and feed the paper up through the print station until the
first page clears the ribbon mask by about one inch. (Figure 16.)
5. Fold a two inch piece of plastic tape over the top sheet, midway between
the sides, as shown in Figure 16 detail A.
