10.1.1 Examples

10.1.2 Motor Control Examples of the Inkjet Print Head Module

Vertical Movement

The vertical motor stepping control logic in the MFC2000 may be used for the Inkjet printing (See Section 12.1).

For Laser printing, this internal vertical motor stepping control logic is not used.

Horizontal Movement

The horizontal stepper motor control logic or the horizontal DC motor control logic should be in the external print

ASIC.

Whenever the external print ASIC needs the new timer value(s) or the PWM value(s) which is used to control the

time interval between steps or the DC motor speed, the external print ASIC generates the interrupt (PRTIRQn) to

the MFC2000 ASIC. Then, the MFC2000 CPU will write the new timer value(s) to the register(s) in the external

print ASIC in the interrupt subroutine.
