Cassette Pickup Control
Description
The DC Controller rotates the Pickup Roller by rotating the Pickup Motor (M1).
The Pickup Arm is lifted and lowered to feed the paper by rotating the Pickup Cam with the Pickup Solenoid (SL3).
Double Feed Prevention Mechanism
This machine employs the Separation Roller method for double feed prevention.
The Separation Roller method of this machine is a method that prevents paper double feeds by using the Separation Roller
without drive.
The Separation Roller is driven and rotated by the Pickup Roller.
• At normal time
The Separation Roller is driven by the Pickup Roller drive via paper. This causes the Separation Roller to rotate in the
feed direction.
• During Double Feed
Since the friction force between sheets of paper becomes weaker when there are multiple sheets of paper, the Pickup
Roller drive force transmitted to the Separation Roller becomes extremely weak. Since force suppressing rotation is
applied to the Separation Roller of this machine, this mechanism does not allow rotation by the weak drive force
transmitted from the Pickup Roller during double feed. The Separation Rollers therefore do not rotate and do not pickup
double feed paper.

Multi-purpose Tray Pickup Control
Description
The Multi-purpose Tray pickup feeds paper from the Multi-purpose Tray one sheet at a time into the machine.
The following describes the operation of the Multi-purpose Tray pickup.
1. When a print command is input from the Main Controller, the DC Controller rotates the Pickup Motor (M1).
2. When the DC Controller turns ON the Multi-purpose Tray Pickup Solenoid (SL1), the Multi-purpose Tray Pickup Roller rotates
and paper is picked up.
3. After double feed paper is removed by the Multi-purpose Tray Separation Pad, paper is fed into the machine. Note that the
presence of paper on the Multi-purpose Tray is detected by the Multi-purpose Tray Paper Sensor (PS6), and printing is not
performed if there is no paper.
