Xerox Customized Envelope Feeder – Problem Solving Guide   4-9 
REP 4.8  Separator Adjustment Procedure 
Overview 
The gate assembly pre-shingles the product to help the feed belts move one piece of product 
at a time based on the gap between the gate assembly and the feed belts. Pre-shingling helps 
the gate to efficiently separate and single-out the product. The gap between the gate and the 
feed belts is adjustable to accommodate different product thicknesses. 
The discharge belts are located under the hold down assembly. 
Combined with the hold down assembly, the discharge belts provide the friction necessary to 
pull the piece of product away from the gate assembly, resulting in a gap between each piece 
of product as it leaves the gate assembly area. 
When feeding product with varying thickness throughout a single piece of product, it may be 
necessary to loosen both adjustment rollers one or two full turns allowing the gate to “float.” 
Purpose 
Adjust the gate assembly so only a single piece of product at a time passes under the gate. 
Procedure 
1.  Turn the power switch to O (off) and remove the power cord from the power source. 
2.  Turn the gate assembly adjustment knob to raise or lower the gate assembly to create 
a gap greater than the thickness of one piece of product.
