Define stacker settings and other adjustments affecting the BFM
There are several factors that may impact stacking quality and overall productivity of the BFM such as
minimizing paper curl, setting stacking limits, improving jam rate, and the use of the variable shaped
tray for betterregistration. The following describeshow to ensure the quality of your output and improve
overall productivity.
Enable/Disable Automatic Image Permanence for All Stock Weights
The Xerox Nuvera is designed to optimize fusing performance across the supported range of paper types
and weights. The BFM uses the paper weight programmed when loading paper to optimize registration
and compiling. Enable the AIP selection from System > User Diagnostics to achieve the best fuse
temperature and minimize curl in the stacked output.
Set BFM Stacker Limits
While the BFM can stack up to 3,000 sheets, it is best to set a stacking limit that is a more comfortable
stack size and not so large and heavy to lift or transport. Setting a manageable limit also helps to avoid
paper curl that can occur in a large stack, which then eliminates the need for operator intervention.
The BFM detects when the stacker is about to reach its limit and automatically schedules an unload
when the next set is completed. If you have two BFMs in the system and one becomes full, the system
automatically switches to the second BFM.
Follow the steps below to set unique stacker limits for each stacker on the system.
1. Select Print Manager > Stacking tab.
2. Right-click on one of the finishing devices and select Stacker Limits.
The Stacker Limits window displays.
3. Set Stacking Limits for each stacker that is available on your system:
• Main Stacker: This field identifies the number of sheets not to exceed in determining when to
unload the BFM main stacker. Select from 200 - 3000 sheets.
• Bindexer Capacity: This field identifies the number of sheets that can be compiled in the BFM
main compiler for unfinished sets only. This feature allows you to control the number of sheets
to be compiled before they are placed onto the stack. Select from 15 - 100 sheets (20 lb paper).
If you leave this field blank, the Automated Bindexer is in effect. The system automatically
calculates the thickness of the unfinished set in the compiler before the sets are placed onto the
stack. The system uses the lower of the manual or automatic setting. Bindexer is set to 100 at
install.
4. Adjust the Bindexer setting to:
• Help reduce excessive curl on sheets (lower the setting)
• Manage special stocks such as coated stock - Improve stacking of some papers (lower the setting)
• Improve jam rate of heavy papers
• Reduce the occurrence of BFM faults and the number of wasted sheets in the compiler (lower the
setting)
• Improve problem jobs by reducing to 35 (if setting is 35 and job is 37 sheets, increase to 37 or
more).
