Review
The V-710DM is shipped to you with a high-tension spring in the
gate assembly. This works well for most materials, allows for tall
stack height, and helps provide the best performance in prevent -
ing doubles. However, certain types of material may demand you
change the gate assembly from a high-tension setting to a low-ten-
sion
setting (for example, irregular shaped material).
If you are feeding a material of irregular thickness, you should
change to low-tension. This provides the following benefits:
1) allows the gate assembly to adjust to the irregular thicknesses.
2) prevents marking on the material by the gate assembly.
3) prevents peeling back the top sheet of a multi-page item.
Procedure
To change the spring from a high to a low tension, follow these
steps:
1. Remove the gate assembly from gate bracket assembly. To
do so, pull cylinder down with one hand, lift up on knob
with other, and tip at slight angle to remove.
2. Remove the adjustment knob by turning counterclockwise
(Figure 3-5A). Then lift the cylinder off of top of spring
(Figure 3-5B).
3. Turn the cylinder around so the cylinder collar faces up
(Figure 3-5C). Then place the cylinder on top of the spring.
4. Replace the adjustment knob (make about 8 revolutions of
the knob before reinstalling gate assembly on gate plate).
Changing From
Factory Set
High-Tension to
Low-Tension
When changing from a low-tension to high-
tension setting, you may have to adjust the
stack height downward to prevent feeding
problems.
Excessive lowering of the gate assembly can
damage material and/or lead to premature
wear of the O-rings or feed belts.
Certain types of single-sheet material may
require even more tension than the high-
tension setting can provide. To increase
tension even further, place a washer between
the cylinder and spring.
