2.8.6 PAPER DELIVERY UNIT DRIVE MECHANISM
The paper delivery unit is driven by the main motor. As the main motor [D] turns,
the main drive timing belt [C] turns. Drive is transmitted to the pulley [B] at the end
of the rubber belt drive roller shaft, through the gears and the timing belt.
The knob [A] can be used to rotate the main motor drive manually. A small plate
normally covers the knob, and it is not accessible for the operator. It is for
emergency use only.
When the knob is turned by hand, it turns the rubber belt drive roller shaft. The
rotation is transmitted to the main drive timing belt [C] via the route opposite to the
normal main motor drive.
At the same time as the knob is turned, the drive position indicator disk [F] turns
through the shaft [E] and two timing belts. The arrow mark on the disk shows the
position of the main motor drive.
If the operator rotates the pressure cylinder by hand while removing the drum, the
main motor drive also turns. It may not be possible to reinstall the drum, because
the position of the drum drive gear will have changed.
If this happens, the knob can be used to turn the main motor drive. When the arrow
on the indicator disk meets the center division, the drive is in the home position.
The drum drive gear also in the home position, and the drum can be reset.
