Staple mode
In the staple mode, the stack of paper is stapled and stacked on the stacking tray. The staple stacker
performs each step on every sheet of paper and then staples the pile of paper. The paper feed operation
for the staple mode includes the following steps:
1. The printer engine outputs the DELIVERY PAPER (/PDLV) signal to the formatter when the leading
edge of paper reaches the delivery paper sensor.
2. When the formatter receives the /PDLV signal, it sends the delivery notice command to the staple
stacker driver.
3. When the delivery notice command is received, the staple stacker driver turns on the deflector
solenoid (SL2100) and allows the delivery deflector to switch the paper-proceeding direction. At
the same time, the driver rotates the leading-end alignment separation motor (M2102) to separate
the upper stacking roller from the lower stacking roller.

4. The staple stacker driver causes the feed motor (M2101) to rotate the feed roller and the lower
stacking roller after a specified interval from when the /PDLV signal has been received.
