Document Pick-up
When the scanner motor [F] starts rotating clockwise, the pick-up roller [A] lowers
to feed the top sheet of the document. The paper is then separated by the reverse
roller [D] and fed to the R0 [E] roller.
Since the R0 roller rotates faster than the feed roller [B], the pick-up roller and feed
roller add to the load on the scanner motor while the R0 roller feeds the document.
To prevent overloading, a spring clutch is attached to the feed roller. Also, the pick-
up roller gear [C] attached to the pick-up roller disengages from the driving gear
train in the case of overload.
The motor is slower during MDF so that the operator can insert the document
easily.
