Timing chart 2-1-14 Reversing of the second face of the original and ejection
a 362 OFM pulses after the scanning of the first face (reverse face) of the original completes and the DF timing switch
(DFTSW) turns off, the switchback pressure solenoid (SBPSOL) turns on, operationg the switchback pulley.
b When the trailing edge of the original turns the original switchback switch (OSBSW) off, the eject feedshift solenoid
(EFSSOL) turns off and the eject feedshift guide returns to the original position, switching the path of the original to
the eject section. Simultaneously,
the switchback feedshift solenoid (SBFSSOL) turns off and the switchback feedshift guide returns to the original
position.
c 30 ms after the original switchback switch (OSBSW) turns off, the original conveying motor (OCM) turns off.
d 135 OFM pulses after the original switchback switch (OSBSW) turns off, the original feed motor (OFM) turns off.
e 100 ms after the original feed motor (OFM) turns off, the motor starts rotating forward, switching the rotational
direction of the switchback roller. The original in the original switchback section is then reversed and conveyed to the
original conveying section.
f 327 OFM pulses plus 100 ms after the original feed motor (OFM) turns off, the motor starts rotating forward again and
the original conveying motor (OCM) turns on simultaneously, conveying the original onto the slit glass.
g 78 OFM pulses after the original is conveyed onto the slit glass and the DF timing switch (DFTSW) turns on, the
switchback pressure solenoid (SBPSOL) turns off.
h 30 ms after the switchback pressure solenoid (SBPSOL) turns off, the original feed motor (OFM) turns off.
i When the scanning request signal turns on, scanning of the second face (front face) of the original starts.
j 2252 OCM pulses plus 30 ms after scanning of the second face (front face) of the original completes and the DF
timing switch (DFTSW) turns off, the original conveying motor (OCM) turns off, completing the ejection of the original.
