Unscheduled set ejection method in a finisher

In a printing machine having a finisher tray for stacking copy sheets, a method of averting a jam comprising the steps of:

• sensing the finisher tray to be near capacity,
• tracking the number of copy sheets remaining to be fed to the finisher tray for a complete set of copy sheets,
• monitoring a value stored in memory representing an approximate capacity remaining in the finisher tray, and
• responsive to tracking the number of copy sheets remaining to be fed to the finisher tray and monitoring the value stored in memory making a determination regarding a potential capacity of the finisher tray.

In a printing machine having a compiler tray for stacking copy sheets, a method of averting a jam comprising the steps of:

• sensing the compiler to be near capacity,
• tracking the number of copy sheets remaining to be fed to the compiler for a complete set of copy sheets,
• monitoring a value stored in memory representing an approximate capacity remaining in the compiler tray, and
• responsive to tracking the number of copy sheets remaining to be fed to the compiler and monitoring the value stored in memory making a determination that the compiler tray cannot accommodate the number of copy sheets remaining to be fed to the compiler.

In a printing machine having a finisher tray for stacking copy sheets, a method of averting excess finisher capacity comprising the steps of:

• sensing the finisher to be near capacity,
• tracking the number of copy sheets being fed to the finisher tray,
• monitoring a value stored in memory representing the capacity of the finisher tray, and
• responsive to tracking the number of copy sheets being fed to the compiler and monitoring the value stored in memory making a determination that the capacity of the finisher tray is being exceeded within an acceptable range.
