Friction feed (release lever in FRICTION POSITION).
The paper must be loaded from the front or top entrance.
Do not use continuous paper.
Do not perform any reverse paper feeds within the top 8.5 mm (.34 in.) or bottom 22 mm (.87 in.) area.
Do not perform reverse feeds greater than 1/6 inch after a paper end has been detected.
Push tractor feed (release lever in REAR PUSH POSITION or FRONT PUSH POSITION).
The paper must be loaded from the front or rear entrance.
Release the friction-feed mechanism.
Do not perform reverse feeds greater than 1/6 inch.
Since accuracy of paper feed cannot be assured after the paper end has been detected, do not perform
reverse feeding after the detection of a paper end.
