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.
Close the right tractor cover.
Adjust the left tractor until the holes in the paper
are centered on the pins then lock the lever and
close the left tractor cover.
Note: If the paper is too loose or too tight it can cause
jams.
Lower the top paper tray and slide it towards the
front of the printer until the marks align.
Press and hold the LOAD/EJECT key to advance
the paper.
Note: The factory default setting for the Top of Form
