CHAPTER 2 FUNCTION & OPERATION
The figure below shows the appearance
of the pickup side of the feed system.
Paper release lever
Roller unit
(Pickup and separation rollers)
Document sensor lever
Document stopper
Feed motor
Figure 2-302
The “paper release lever” appears on
the left side of the above figure. If it is laid
towards the far side, the separation pad is
lowered, releasing the separation mecha-
nism. If the document is jammed, use this
lever to release the separation mechanism
to easily remove the jammed document.
When closed, the feeder cover pushes the
paper release lever to the original position,
that is, the separation mechanism is set
again. The conventional, sheet-fed type
scanners release the separation when
scanning one sheet. On the other hand, this
machine has a flatbed and uses it in princi-
ple for one-sheet scanning.
The “document sensor lever” is placed
on the right side of the roller unit. When
correctly set, the document pushes and
rotates this lever, which turns the document
sensor on. Unless the document is pushed
until the document sensor is turned on, the
machine does not determine that the
document is set.
The “document stopper” is mounted
beneath the roller unit. After the document
sensor is turned on, the document being
pushed towards the far side reaches the end
of this stopper. When the feed action starts,
the roller unit, and at the same time the
stopper, lower down, so that they do not
interrupt the document feed. Note, however,
that a document of a great number of sheets
or hard documents may push the stopper
down, causing the leading edge of the
document to reach the separation area.
However, the document is correctly fed.
