6.11.3 INVERTER MECHANISM

The paper is fed to the duplex path in duplex mode after junction gate 1 [A] opens the
duplex path. The duplex inverter motor moves the paper into the inverter, as far as the
switching back position. The duplex inverter plate always closes the path to the inverter by
spring tension. However, this spring tension is low, so the force from the leading edge of
the paper can open the duplex inverter plate.
Then, after the duplex entrance sensor [C] detects the trailing edge of the paper, the duplex
inverter motor stops, and the duplex inverter plate [B] opens the duplex feed path (the plate
is always open by spring tension). Then, the duplex inverter motor reverses and moves the
paper from the switching position to the duplex feed path.
In the duplex feed path, the paper is fed by the transport rollers (these rollers are driven by
the duplex inverter motor) and the duplex/by-pass transport roller (this roller is driven by the
duplex/by-pass motor). When the machine gets a multi-page duplex printing job, the duplex
exit sensor [D] controls the duplex inverter motor and duplex/by-pass motor to synchronize
the duplex feed timing.
