●
Delivery stationary jam
If the paper-delivery sensor (PS1302) does not detect the trailing edge of the paper within a
prescribed period of time after the feed motor has started its drive after the staple operation, the
CPU detects a delivery stationary jam.
●
Residual-paper jam
If the paper inlet sensor (PS1301) detects paper during the initial drive period, the CPU detects
a residual-paper jam.
Stapler unit
The stapler motor (M1304) is installed in the stapler unit. The staple operation is performed by the
stapler/stacker driver controlling M1304. In addition, the stapler unit has three sensors to detect the
condition of the stapler unit.
NOTE The staple cartridge holds a maximum of 5,000 staples.
