AR-6020V OPERATIONAL DESCRIPTIONS 11 – 3
B. Operational descriptions
(1) Document size detection
Size detection on the document tray
The document width is detected with the RSPF document width
sensor (SPWS), and the document length is detected with the
RSPF document length sensors (SPLS1, SPLS2). The document
size is judged from the document width and the document length
according to the table below.
RSPF unit
(2) Document scanning
The document scanning mode is available in 300dpi, 400dpi and
600dpi.
(3) RSPF paper feed and transport operations
a. Paper feed operation
The paper exit motor is turned ON and the power of the paper exit
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
prevent double-feeding.
b. Single face scanning
The lead edge of the fed document is aligned (registration) by the
registration roller, and passed through transport roller 1 to the doc-
ument 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.
1) Document set (Document empty sensor ON)
2) Paper feed start (1st sheet)

Or the paper feed clutch is ON. )
3) Registration operation (1st sheet)
(Registration clutch ON)
(When a certain time passes after turning ON the registration
clutch, the paper feed clutch is turned OFF.)
