OUTLINE OF THE MACHINE
3 - 73
8. Empty sensor (S75/S83/S91/S99)
This is a transmissive-type sensor and detects the availability of paper in the drawer by using an
actuator. When there is no paper in the drawer, the actuator blocks the light path of the sensor, and
the sensor determines that there is no paper.
9. Feed sensor (S78/S86/S94/S102)
This sensor detects if the leading edge or trailing edge of the paper has passed the feed roller. It
also detects jamming such as misfeeding.
10.Transport sensor (S77/S85/S93/S101)
This is a reflective sensor whose purpose is to directly detect if paper is set or not, without using any
device such as a sensor arm. Transport sensor detects if the leading edge or trailing edge of paper
passed the transport roller. They also detects jams like misfeeding.
11.Registration sensor (S52)
This sensor detects that the leading edge of the paper has reached the registration roller and the
trailing edge of the paper has passed the registration roller.
12.Drawer tray-up sensor (S76/S84/S92/S100)
This sensor stops the tray at the predetermined height when the tray is moved up. When the tray-up
sensor is turned ON, the tray-up motor is turned OFF to stop the upward movement of the tray.
13.Drawer detection sensor (S73/S81/S89/S97)
This sensor detects if the drawer is fully inserted.
14.Feed clutch (3rd drawer (CLT5) / 4th drawer (CLT7))
This is a clutch used to transmit the drive from the feed/transport motor to the drawer pickup roller
and drawer feed roller.
15.Drawer transport clutch (3rd drawer (CLT4) / 4th drawer (CLT6))
This is a clutch used to transmit the drive from the feed/transport motor to the transport roller.
When the clutch is turned ON, the transport roller rotates at high speed to transport paper.
16.Feed/transport motor (M43)
This motor drives the pickup rollers, feed rollers and transport rollers of the drawers and bypass tray.
17.Registration motor (M39)
This motor drives the registration roller. This stepping motor transports paper in the transfer direction
in time with the image transfer to align the paper with the leading edge of the image.
18.Tray-up motor-1/-2 (M44, M45)
When this motor rotates normally, the tray in the 1st drawer moves up, and when the motor rotates
reversely, the tray in the 2nd drawer moves up.
19.Bypass motor (M12)
This stepping motor drives the bypass pickup roller, feed roller and transport roller.
20.Bypass pickup solenoid (SOL8)
This is a solenoid to move down the bypass pickup roller.
21.Bypass paper size detection sensor (S70)
This sensor works directly with the sidewalls of the bypass tray to detect the paper width on the tray.
22.Drawer paper size detection sensor-1/2 (S79/S80/S87/S88/S95/S96/S103/S104).
These sensors detect the size of the paper placed in each drawer.
Paper sizes can be detected with the combination of switch signals that are sent by the movement
of the end and side guides in each drawer.
