(1-2) Paper feed from the bypass table
The bypass table can hold up to 50 sheets of paper at one time.
When the print key is pressed, the bypass solenoid (BYPSOL) turns on, rotating the bypass
upper pulley, while the bypass lift is raised until the paper comes into contact with the bypass
upper pulley. The paper on the bypass table is then conveyed to the secondary paper feed
section.
The bypass lower pulley rotates opposite to the paper feed direction so that the torque limiter
prevents multiple sheets from being fed at one time.

A
When the print key is pressed, the bypass solenoid (BYPSOL) turns on for 250 ms, which
raises the bypass lift and rotates the bypass lower pulley to perform primary paper feed.
The paper is then fed by the upper and lower registration rollers until the 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 of the paper turns the registration switch (RSW) off, the
registration solenoid (RSOL) turns off to complete secondary paper feed.
