Always move the paper-release lever to the position indicated
for the paper-feeding method you are using.

Make sure you align your paper supply with the paper loaded
in the tractor so the paper feeds smoothly into the printer.
If you want to feed paper through the bottom paper slot, use a
printer stand that has a large enough opening for paper to feed
from the bottom without obstruction.
Changing tractor positions
You can use the tractor unit as either a push tractor or a pull
tractor. You can change the tractor position according to your
paper feeding method. The printer comes with the tractor
installed in the push-tractor position.
