Motors
See “Timing Diagram” on page 5-47 for specific timing details for the
printer motors.
The Main Motor, MT1, is controlled by the DC Controller Board. The
Main Motor drives the main Gear Assembly and rotates during the
Initial Rotation period (following power-on), the Print period, the Last
Rotation period, or whenever the printer’s Top Cover is opened and
closed.
Figure 5-5 Main Motor Control
The Main Motor is a DC brushless motor with hall elements, and is
unified with the motor drive circuit.
The CPU (IC501) sets the main motor drive signal (/MON) to “L” and
rotates the main motor. When printing at 1200 dpi, the CPU sets the
main motor rotation switching signal (/HALF) to “L” and decreases the
rotation speed of the main motor to half.
