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