NOTE:
Paper End is also known as paper out
Whenever the release lever is in the Tractor (Continuous) Feed position, paper end is detected by the
microswitch on the push tractor (

Whenever the release lever is in the Friction (Sheet) Feed position, Paper End is detected by a
photosensor (

When the printer detects an out of paper condition, the PEN (Paper End) signal goes low, the printing is
stopped and the ALARM LAMP is turned ON.
