3.11.3 Functions
1. Drawer feed roller
Draws out paper on the paper feed drawer one by one and conveys to the registration roller.
One sheet of paper is transported to the registration roller each time the drawer feed roller
completes one rotation.
2. Drawer feed clutch (CL2)
This is an electromagnetic clutch which drives the drawer feed roller. When the drawer feed clutch
(CL2) is turned ON, the driving force from the main motor (M3) is transmitted to the drawer feed
roller in the drawer to rotate it.
3. Paper empty sensor (S5)
This is a transmissive-type sensor and detects the availability of paper in the drawer. 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.
4. Bypass feed roller
Transports the paper from the bypass feed roller to the registration roller.
5. Bypass separation pad
When two or more sheets of paper are transported from the bypass feed roller, since the resistance
force of the bypass separation pad is larger than the frictional force between the sheets, the lower
sheets are not transported any further.
6. Bypass paper sensor (S6)
Detects whether paper is set in the bypass tray or not. When paper is set in the bypass tray, bypass
feeding is performed in preference to drawer feeding. And it also detects whether paper has been
transported from the bypass tray or not (i.e. whether the leading/trailing edge of the paper has
passed the bypass feed roller or not.). The sensor is also used to detect jams such as paper
missending in the bypass unit.
7. Bypass feed clutch (CLT3)
This is an electromagnetic clutch which drives the bypass feed roller. When the bypass feed
clutch(CLT3) is turned ON, the drive is transmitted from the main motor (M3) to rotate the bypass
feed roller.
8. Registration roller
Paper transported from the drawer feed roller or bypass feed roller is pushed against the registration
roller which aligns the leading edge of the paper. Then, the registration rollers rotate to transport the
paper to the transfer position.
9. Registration roller clutch (CLT1)
This is an electromagnetic clutch which drives the registration roller. When the registration roller
clutch (CLT1) is turned ON, the drive is transmitted from the main motor (M3) to rotate the
registration roller.
10.Registration sensor (S2)
It is used to detect that the leading edge of the paper has reached the registration roller and to
control the aligning amount of the paper (the amount of the paper bend before it is transported to the
registration roller). Also, it is used to detect the trailing edge of the paper has passed the registration
roller.
