Frequently an electrophotographic printing machine utilizes a stapling system in order to staple sets of copies. A pneumatic system is used to actuate the stapler. If the stapling stroke fails to occur at the proper time, a staple jam may very well occur. In order to avoid the occurrence of a staple jam, a microswitch may be positioned at the end of the head driving staple through the sheet. If the microswitch detects that the driver has not driven the staple through the set of sheets at the proper time, the printing machine is shut down.
