10.2.4 Reversal Operation
0013-1196
There are two types of reversal operations, reversal from the top side to the reverse side and reversal from the
reverse side to the top side. However, since their operating principles are the same, only reversal from the top
side to the reverse side is described below.
a. When the ADF motor (M2001) turns and the registration solenoid (SL2002) turns on, the registration roller
turns to feed the paper along the platen guide for surface scanning. After completion of scanning, the paper is
fed to the delivery unit by the transport roller 1 and delivery roller.
F-10-7
b. Reversal/Feed 1
When the predetermined time has lapsed since the trailing edge of the fed original pa ssed through the document
edge sensor (SR2002), the ADF motor (M2001) stops. Immediately after this, the ADF motor turns in the
reverse direction to feed the original to the registration roller and the roller release solenoid (SL2003) turns on
to release the delivery roller.
