A
When the print key is pressed, the paper feed solenoid (PFSOL) turns on for 250 ms,
rotating paper feed pulleys A and B to perform primary feed. Then the paper is fed by
the upper and lower registration rollers and its leading edge stops at the registration
stopper to create slack in the paper before registration.
B
The leading edge of the paper turns the registration switch (RSW) on.
C
The scanner starts scanning and the home position switch (HPSW) turns off. After 147
140 ms, the registration solenoid (RSOL) turns on and the registration stopper
lowers. The lower registration and pre-transfer rollers convey the paper to start
secondary feed.
D
100 ms after the trailing edge has turned the registration switch (RSW) off, the registration
solenoid (RSOL) turns off to complete secondary paper feed.
