ENWW Pickup/feed system 183
Fuser/delivery unit
The fuser/delivery unit, being comprised of the fuser and the delivery unit, feeds paper from the
fuser to a delivery tray (either the face-up tray or the face-down tray).
The available tray is switched as the face-up tray opens and closes. Open the face-up tray for
face-up delivery, and close the tray for face-down delivery.
The following is the sequence of paper feed at the fuser/delivery unit.
1 The paper after the secondary transfer is fed into the fuser.
2 The paper is pressed between the fuser sleeve and the pressure roller to fuse the toner on top
and then delivered out of the fuser.
3 When the leading edge of the paper is detected by the fuser delivery paper sensor (PS7), the
delivery motor (M2) drives and rotates the delivery roller.
4 When the paper end is detected by the fuser delivery paper sensor (PS7), the M2 rotates at
double-speed and delivers the paper out to the face-down tray at high speed.
Note The feed speed is accelerated after paper passes away from the fuser when delivering from the
face-down tray because the fuser is far from the tray.
