Signal name Name Type Function/Operation
SPFM RSPF transport motor Stepping motor Transports a document.
SPM/SPUM RSPF paper feed motor Stepping motor Feeds a document.
SPRS Paper exit roller pressure control solenoid
(RSPF)
Magnetic solenoid Controls ON/OFF of the transport power of the paper exit roller. (Releases the
paper exit roller pressure when reversing paper.)
SRRC Registration roller clutch (RSPF) Magnetic clutch Controls the registration roller. (Controls the timing of document transport.)
STMPS Stamp solenoid Magnetic solenoid Drives the finish stamp.
No. Name Function/Operation
1 RSPF driver PWB Drives the motor, the solenoid, and the clutch in the RSPF section.
