MX-3114N OPERATIONAL DESCRIPTIONS 13 – 55
(3) RSPF paper feed and transport operations
a. Paper feed operation
The paper feed motor is turned ON and the power of the paper feed
motor is transmitted to the pickup roller and the paper feed roller.
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 separated 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.

clutch, the paper feed motor is turned OFF.)
7) Scanning start (2nd sheet)
8) Paper exit complete (1st sheet)
9) Scanning complete (2nd sheet)
10) Paper exit complete (2nd sheet)
