3. OPERATIONS AND TIMING
3. Detecting the Size of Originals
Using the combination of the outputs of the
sensors representing the presence/absence of an
original, the image processor PCB identifies the
size of the original as shown in Tables 3-206
through -208.
• Same
Indicates that there is no change in the sensor
output, i.e., the presence of an original is
assumed. (The sensor output is checked every
128 ms after the copyboard cover has turned
ON.)
• Different
Indicates that there is a change in the sensor
output, i.e., the absence of an original is
assumed. (The sensor output is checked every
128 ms after the copyboard cover has turned
ON.)

4. Identifying the Size of Originals by
the Feeder
The feeder (option; RDF-G1/ADR-F1) detects
the original width/original length and communi-
cates the result to the image processor.
a. RDF-G1
The RDF-G1 identifies the size of an original in
reference to the width detected by the side guide
plate and the length detected in feeding direction.
As such, the size is identified when the original is
picked up; the sizes that can be detected are any
of the following default sizes:
A-configured:
A5, A4, A4R, A3
B-configured:
B5, B5R, B4
Inch-configured: STMT, LTR, LTRR,
FOOLSCAP, LGL, 11"×17"
b. ADF-F1
The ADF-F1 identifies the size of an original in
reference to the width detected by the side guide
plate and the length detected by the three sen-
sors located on the ADF. As such, the size of an
original is detected when it is placed in the feed-
er; the sizes that can be detected are any of the
following default sizes:
A-configured:
A5R, A5, A4, A4R, A3
B-configured:
B6, B6R, B5, B5R, B4
Inch-configured: STMT, LTR, LTRR,
FOOLSCAP, LGL, 11"x17"
