4. When the stack in the processing output bin is sent to the delivery output bin and the trailing
edge of the first and second paper exits the first delivery roller, the stack-delivery roller and
return roller deliver the first and second sheet to the processing output bin.

5. The first and second paper delivered to the processing output bin are aligned and then delivered
to the output bin.

Output bin operation
This accessory has an upper output bin (output-bin 1) and a lower output bin (output-bin 2).
●
The output-bin-1-shift motor (M107) and output-bin-2-shift motor (M108) move output-bin 1 and
output-bin 2 up and down independently.
●
The output-bin-1 paper sensor (PI111) and output-bin-2 paper sensor (PI112) detect paper
stacked on the output bin.
●
The output-bin-1 paper-surface sensor (PI141) and output-bin-2 paper-surface sensor (PI115)
detect the home positions of output-bin 1 and output-bin 2.
●
The home position is the top surface of the paper when paper is stacked on the output bin, or
the position where the edge of the output bin is detected when no paper is stacked.
●
When the power is turned on, the stacker controller PCA drives the output-bin-1-shift motor
(M107) and output-bin-2-shift motor (M108) to return the output bin to home position. If already
