6.12.2 JUNCTION GATE MECHANISM
To the Standard Tray
The paper exit rollers [A] feed paper to the standard tray. These rollers are driven by the
fusing/paper exit motor [B].
When a sheet of paper stays in the paper exit unit, the paper exit sensor [C] detects the
paper jam and xxxxx is displayed.
When outputs push up the tray full actuator [D], the paper overflow sensor [E] detects that
standard trays is full of outputs and xxxx is displayed after a job end.

To the inverter tray 7. To the standard tray After fusing, the junction gate feeds paper to the standard paper tray or the inverter tray. The junction gate solenoid controls the junction gate as follows: ƒ To the standard paper tray: The junction gate solenoid is off (default) ƒ To the inverter tray: The junction gate solenoid is on. The fusing/paper exit motor drives the paper exit rollers.

When outputs push up the tray full actuator [D], the paper overflow sensor [E] detects that standard trays is full of outputs and xxxx is displayed after a job end. To the Inverter Tray When paper is fed to the inverter tray, the junction gate [A] closes the paper path to the standard tray. And then, the inverter roller [B] feeds paper to the inverter tray. This roller is driven by the duplex inverter motor [C].

The drawing above shows the paper movement with the interleave method for three sheets of paper. The printing is done as follows:
SM 6-79 B230/B237 Detailed Descriptions From A4/LT (81/2 x 11) LEF to 400mm length There are two sheets of paper in the paper feed path at the same time. The interleave method is used. For sheets longer than 400 mm, there is no interleaving. The drawing above shows the paper movement with the interleave method for two sheets of paper. The printing is done as follows:
