[ 1 ] Tray Area
The tray area consists of the recording paper tray and paper end sensor. The paper end sensor deter-
mines if the recording paper tray is empty.
• Recording paper tray
Tray in which recording paper is loaded. The sizes of paper that can be set are A4, Letter and
Legal (A4, LT & LG). (
• Paper end sensor
Detects the presence of recording paper in the recording paper tray. The sensor is located in the
upper part of the tray base. (P.6-10 "Fig.6-13")
[ 2 ] RX Drive Area
The RX drive area consists of the RX drive gear assembly, RX motor, paper pickup roller, paper pickup
solenoid, paper position sensor and paper exit sensor. It conveys the power of the RX motor to each
area of the reception section and functions to feed recording paper.
• RX drive gear assembly
The RX drive gear assembly drives rollers, drum, fuser, etc., and is driven by the RX motor.
• RX motor
The RX motor is the only drive source in the reception section. When reading of the receive data
from the remote station or copy data of one document page is complete, the RX motor rotates.
• Paper pickup roller
The paper pickup roller supplies the recording paper from the recording paper tray. The roller is
driven by the RX motor, but the timing of its rotation is controlled by the paper pickup solenoid.
• Paper pickup solenoid
The paper pickup solenoid controls a timing of the paper pickup roller rotation. The solenoid turns
on so that the image on the recording paper matches with the image on the drum surface.
• Paper position sensor and paper exit sensor
The paper position sensor and paper exit sensor detect the status of recording paper feeding.
The paper position sensor is located before the paper feed roller while the paper exit sensor is
located in the upper of the fuser.
A timing of turning on the paper position sensor and paper exit sensor after the recording paper
is supplied from the recording paper tray is monitored to detect a paper jam.
