Pull Tractor Method

Using pull tractor feed to advance the paper is basically the same as using push tractor feed. In push

tractor feed, the TRACTOR ASSY. (paper advance mechanism) is before the paper entrance. It pushes

the paper through the PRINTER MECHANISM. Pull tractor feed, however, has the opposite arrangement,

with the tractor situated after the paper entrance. Since it pulls the paper through the PRINTER

MECHANISM, it requires no paper tension unit. Figure 2-6 illustrates pull tractor operation tractor when

paper is inserted through the bottom path.

Push-Pull Tractor Method

This is a combination of the push tractor and pull tractor methods. Two tractors are used, one in front

of and one behind the paper entrance, to advance the paper. They act simultaneously to push and pull

the paper through the PRINTER MECHANISM. Figure 2-7 illustrates push-pull tractor operation.
