FS-107
1. Operation
a. Stapler operation
After the aligning operation of the last paper, M707 is
turned ON and compresses the paper using the exit
rollers. Then, M708 is turned ON and stapling begins.
When PS701 is turned OFF, M707 is turned OFF,
PS712 is turned ON, and M708 is turned OFF.
For continuous stapling, M705 is not turned ON, and
the stapler unit waits for the next stapling at the same
position.
In the case of 2 stapling positions, the first staple is
executed and then M705 moves the stapler to the
specified position for the second staple. M708 then
turns ON and executes the second staple. At this
moment, if continuous stapling has been selected,
the stapler unit stops at the immediately previous
stapling position. When the first stapling operation of
the next paper is done, M705 moves the stapler unit
for the second stapling operation.
After the copy is finished, the stapler unit returns to its
home position.
b. No-staple detection control
The PS713 is equipped to detect the no-staple
condition of the stapler unit. When the staple is not
present, the LCD (display board) of the main unit
shows a message indicating the no-staple condition.
c. Stapler Initial Operation
After replacing the stapler cartridge, M708 is driven
until staples are detected in the PS714, performing
up to a maximum of 16 blank stapling operations,
then the staples are positioned just in front of the
stapling position.
