(3) Conveying section
The conveying section conveys paper to the transfer/separation section as paper feeding from the cassette or
MP tray, or as paper refeeding for duplex printing. Paper by feeding is conveyed by the paper feed roller to the
position where the registration sensor (RS) is turned on, and then sent to the transfer/separation section by
the upper registration roller and lower registration roller.
