16-6. Synchronizing Roller Drive Control
•
The Synchronizing Rollers are driven by Synchronizing Motor M4.
•
M4, a stepping motor, is controlled by energizing the four internal coils
using pulse signals output from pins 2, 3, 6, and 7 of IC2T on
Synchronizing Motor Control Board PWB-T, as controlled by Master Board
PWB-A.
•
The Synchronizing Rollers are started in synchronism with the Registration
signal (TRON).
*
The BASE signal is output when the Scanner reaches a given point in its
scan motion.
*
The TRON signal is output from Scanner Control Processor Board PWB-J
at a given time after the Image Leading Edge signal (BASE) has been
output.
•
The Synchronizing Rollers are stopped at a given time after the trailing
edge of the paper has moved past Paper Leading Edge Sensor PC27.
•
The Synchronizing Rollers are driven at the following timing.
