tractor.
Important! You must keep the number of paper holes engaged on
either pin the same. If you don't the paper will skew and jam.
8. Close the right tractor cover.
9. Adjust the left tractor until the holes in the paper are centred
on the pins then lock the lever and close the left tractor cover.
If the paper is too loose, or too tight, it can cause jams.
