8.4 Duplex Unit
8.4.1 Outline
0016-7806
The duplex pickup operation of this machine is performed by driving the main motor (M1) under the control of the CPU installed on the DC controller PCB. When
the trailing edge of the paper finished with printing on its top surface reaches the point 10 mm away from the delivery sensor (SR5), the duplex drive solenoid (SL1)
turns on and the drive power of the main motor is transmitted to the delivery roller and duplex drive roller. Paper is led to the duplex unit through the reverse rotation
of the delivery roller, and then fed to the registration roller via the duplex drive roller.
The paper transport for duplex printing is not provided with a sensor that detects arrival or passage of paper.
The duplex unit does not have a function of stopping and holding paper temporarily.
The sequence of duplex printing of the original (e.g., two sheets of original) is: reverse side of first sheet (the memory function is used.) -> top side of first sheet -
> reverse side of second side -> top side of second sheet.
