Intermec ColorCoder V4 – Service Manual Ed. 1
Roll Motor
The roll motor drives the roll drive shaft. When a control signal is
output from the formatter PCB, a motor drive signal is output from
the roller holder PCB, and the rotation of the motor is controlled so
that the paper is supplied by a necessary length.
See Chapter 2.1 Basic Operation, I Motor Control for the drive and
control of the roll motor.
Feeder Motor
The feeder motor drives the feeder belt. The paper to be fed is
controlled by the motor drive signal issued from the engine 1 PCB.
The normal feed speed is 150 mm/sec; however, the speed will
decrease for the following cases.
1. While the head temperature is increasing, the printing operation
is executed at a speed of 50 mm/sec.
2. The partial rewriting including variable data spend some time in
developing data. A printing speed is selectable in "PRINT
MODE SET" in "MAINTENANCE MODE" on the control
panel. The default is 150 mm/sec.
If it does not catch up with a given speed for developing image data,
the feeding of paper pauses every print of 1 page.
See Chapter 2.1 Basic Operation, I Motor Control for the drive and
control of the feeder motor.
