Section 2-1
Chapter 2 Description of scanner operation
2-1 ADF unit
(1) Paper separation
When scanning, bottom sheet of the document loaded on the ADF paper chute (Chute unit) is picked by the Pick roller and
Pad ASSY and fed into the ADF. Picked document is transported by the feed roller and ejection roller at the speed that
corresponds to a specified output resolution until they are ejected to the stacker. ADF unit includes Sensor TOP for page
edge detection, Sensor PICK for picking detection, Sensor EM for paper empty detection, US sensors for multi feed
detection and Cover open sensor. For document specification refer to
Section 1-2
.
(2) Consumables
The Pick roller and Pad ASSY are the consumables and replaced by user. (Refer to
Section 1-8-1
for detail)
The scanner supports two consumable counters, Pad counter and Pick counter, to indicate the number of sheets that have
been scanned from the last consumable replacement. Those counters are checked by the driver for user, or by
Maintenance mode #5 (See
Section 5-1-6
) for service person. After replacing the consumable these counter shall be reset.
(3) Drive unit
The Pick roller is driven by the Pick motor, and feed roller and ejection roller are driven by the LF motor. The motor drive
circuit and motor fuse are located in the Control PCA. If abnormal electric current runs through the motor drive circuit,
the current is cut off by the motor fuse.
(4) Paper thickness switch
When the paper is thinner than described in
Section 1-2-2
, this switch may be effective. This does not assure the scanning
of the thin paper out of the paper specification described in
Section 1-2
. See
Section 1-1
(4) for detail.
