6. PAPER TRANSPORT
• The paper transport mechanism transports copies fed from the copier through the Horizontal Unit into the designated bin.
1. Non-Sort Mode
• All copies are fed into the Non-Sort Bin.
2. Mail Sort Mode
• Copies are sorted into different bins.
The sequence of bins through which copies are fed can be designated in the order from
the Non-Sort to 10th Bin or from the 10th to Non-Sort Bin.

(2) Non-S or t B i n Pa per Transport Mechanism
• In the Non-Sort mode, copies are fed into the Non-Sort Bin.
• Drive from the motor turns the Exit Roller, which feeds the copy into the Non-Sort Bin.
• The path into the Non-Sort Bin is selected when the Non-Sort Bin Solenoid is energized.
