Introduction

The Power Paper Stacker (Figure A–1) maintains a constant distance
between the paper exit path and the stack of printed paper. A phototransistor
senses an infrared beam to determine this distance and triggers the pulley
motor to lower the paper rack.
This appendix contains removal/installation procedures for power paper
stacker components replaceable at the field service maintenance level. For
the page location of removal/installation tasks, consult the table of contents
on page A–1.
