PRINCIPLES OF OPERATION
2.1.2.2 Motors
This printer has the following motors:
Carriage motor (stepper motor)
Paper-feed motor (stepper motor)
Carriage Motor
The carriage motor is used to move the carriage right and left along the platen. This unit employs a four-
phase, 48-step motor using either 1-2 or 2-2 phase excitation and is controlled by an open-loop system.
Paper-Feed Motor
Paper is fed using a four-phase, 48-step motor operating with either 1-2 or 2-2 phase excitation, which ad-
vances the paper either 1/180 inch or 1/360 inch for each phase switch. The CPU controls the motor through
an open loop.
2.1.2.3 Printhead
Figure 2-13 shows the dot-wire operation. When the head-driving coil is energized, the dot wire is pushed
out. The dot wire strikes the ribbon, causing the ribbon to impact the paper, thereby printing a dot.
