a When copying onto the reverse side, 500 ms after the registration clutch (RCL) turns on, the feedshift solenoid
(FSSOL) turns on, operating the conveying shift guide to switch the paper path to the duplex unit.
b When the eject switch (ESW) turns on, the duplex eject switching solenoid (DUPESSOL) turns on to operate the
switchback feedshift guide.
c When the duplex feedshift switch (DUPFSSW) turns on, the duplex forwarding clutch (DUPFWDCL) turns on, rotating
the duplex switchback roller in the forward direction to convey paper to the duplex section.
d 90 ms after the eject switch (ESW) turns off, the feedshift solenoid (FSSOL) turns off.
e 100 ms after the duplex feedshift switch (DUPFSSW) turns off, the duplex forwarding clutch (DUPFWDCL) turns off.
f 50 ms after the duplex forwarding clutch (DUPFWDCL) turns off, the duplex reversing clutch (DUPREVCL) turns on
to rotate the duplex switchback roller in the reverse direction.
g 30 ms after the paper enters the duplex section and the duplex jam detection switch (DUPJSW) turns on, the duplex
pressure release solenoid (DUPPRSOL) turns on and the duplex switchback pulley lowers. The paper is then
switched back by the duplex switchback pulley and duplex switchback roller and re-fed by the refeed roller.
h 120 ms after the duplex pressure release solenoid (DUPPRSOL) turns on, the duplex reversing clutch (DUPREVCL)
turns off and the duplex switchback roller stops.
i 730 ms after the duplex jam detection switch (DUPJSW) turns on, the duplex pressure release solenoid
(DUPPRSOL) turns off.
j When copying onto the front face is complete and the eject switch (ESW) turns off, the duplex eject switching
solenoid (DUPESSOL) turns off.
