CHAPTER
II
THEORY OF OPERATION
This chapter describes the printer functions, the relationship between the electrical systems and
mechanical systems, and the timing of operations. Striped conduits ( ) indicate mechanical
linkages; solid thin arrows ( ) appearing with a signal name indicate the transmission of
single control signals and outlined thick arrows ( ) indicate the transmission of groups of
signals.

BASIC OPERATIONS
1.1 Mechanical Configuration
The printer functions can be divided into four blocks: the laser/scanner system, the image
formation system, the paper pick-up/feed system and the control system.
