Tractor Method
The pull tractor advances paper in basically the same way as the push tractor. The push tractor is installed
at the paper entrance and pushes the paper into the printer mechanism. The pull tractor, however, is installed
at the paper exit and pulls the paper out of the printer mechanism. As the result, the paper tension unit is not
required.
Figure 2-7 illustrates pull tractor operation when the paper is fed through the bottom paper entrance.
