Basic operation
The HP Color LaserJet 5500 series printer’s functions are divided into four systems:
● engine control system
● laser/scanner system
● image formation system
● pickup/feed system
This chapter describes each of these systems thoroughly.
Figure 5-1.
Basic system operation
Operation sequence
A microcomputer in the engine control system controls the operation sequence for the
printer.
Table 5-1. Basic operation sequence describes the main operational periods from
the point when the printer is turned on until a print operation is completed and each motor
stops rotating.
Note
In the table below, "ETB" stands for "electrostatic transfer/transport belt." This component is
described later in this chapter, as are the other components mentioned in the table.
