B. Operational descriptions
(1) Document size detection
Size detection on the document tray
The document width is detected with the RSPF document width sen-
sor (SPWS), and the document length is detected with the RSPF doc-
ument length sensors (SPLS1, SPLS2). The document size is judged
from the document width and the document length according to the
table below.

(3) RSPF paper feed and transport operations
a. Paper feed operation
The transport motor is turned ON and the power of the transport
motor is transmitted to the pickup roller by turning ON the paper feed
clutch.
The pickup roller descends to pickup the top document and feed it to
the paper feed roller.
The paper feed roller feeds a document to the transport section.
At that time, the document is separated by the separation roller to pre-
vent double-feeding.
b. Single face scanning
The lead edge of the fed document is aligned (registration) by the reg-
istration roller, and passed through transport roller 1 to the document
scanning section, where images are scanned.
Then the document is passed through transport roller 2 to the paper
exit roller.
The rollers (the registration roller, transport rollers 1 and 2, the paper
exit roller) in the transport section are driven by the transport motor.
The paper exit roller (drive pulley) is pressed by the paper exit roller
pressure control solenoid.
When the read edge of the document passes the scanning section, the
both rollers are brought into close contact to supply the power for
paper exit.
