ADJ 1.13 Partial Close Adjustment
In order to remove the cut wire from the Holder module, the Closer will
clamp down on the wire prior to moving away from the Holder. The
amount of travel for this motion is called the Partial Close.
If the partial close value is set too high, the Closer will get stuck when
moving away from the Holder. This will occur primarily when the book
thickness is close to the max thickness for a given size.
If the partial close value is set too low, the book may fall out of the Closer
during transfer. Poor roundness on only one size element could also be a
symptom of partial close too low.
Inspection Procedure
1) Access the Service Menu and select Function Tests

Element Cycle

Feed Element

Partial Close.
2) Open the top cover. The closer jaws should have a cut wire held inside
the jaws and partially clamped.
3) Using a hook, Allen wrench, or similar tool, attempt to pull the wire out of
the Closer jaws. If the element slips out freely with minimal force, the
Partial Close is set too low. Repeat this test on the front and rear.
4) If the element is securely held, try running a book with max sheet
thickness. Verify if a bind jam occurs. If a bind jam occurs, the partial
close is likely set too high.
5) If the clamping force seems different on the front and rear, verify that the
closing is even across the element. Refer to ADJ 1.11
Adjustment Procedure
1) Access the Service Menu and select PARTIAL CLOSE
2) Increase or decrease the Partial Close value based on your findings from
the Inspection Procedure.
3) Repeat the steps in the Inspection procedure to verify if the new value is
correct.
4) If partial close seems correct, run several books to determine if the
problem is resolved. If not, return to the section that directed you here.
ADJ 1.14 Element Xfer Position Adjustment
The element transfer position controls the position of the wire while it is
being transferred from the Element Feeder to the Holder. Changing this
value will adjust the amount of travel for the element feed belt prior to
transferring the wire.
1) If the element transfer position is off, the most likely result is difficulty
with successfully picking up the wire and placing it onto the Holder.
2) Check for consistent issues with wire falling off the Holder. The wire
could be completely off the Holder and loose inside the machine. It
could also be poorly held on the Holder and partially fall off during
operation.
3) If these issues are seen, changing the Element Xfer Position may
help.
4) Always note the initial setting so you can return to this value if
needed.
Adjustment Procedure
1) Use an interlock cheat in the interlock of the top cover so that the top
cover can be left open.
2) With a spool in the machine perform the element transfer function test

3) An element will feed, cut and transfer towards the holder but stop
before the element is placed on the holder.
