Close the tractor flap and slide the tractor to the
right until the paper is slightly tensioned.
Do not tension the paper excessively
to avoid tearing the perforation ho-
les; do not allow excessive slack
since in this case the paper will bulge
and there may be problems in the
feeding process.
Then lock the tractor.
