Element Closing; Element Unevenly Closed; Element Insufficiently Closed; Element Over Closed - GBC eWire Service Manual

3.1 Element Closing

Use the following procedure to correct books that are over-closed
or under-closed by the eWire. To determine if an element is
over-closed or under-closed, refer to the diagram below.
Dimension X Max. 2.00mm
Dimension x Min. 0.25mm
3.1.1

Element Unevenly Closed

The element is considered unevenly closed when The "X"
dimension on one side of the binding varies from the "X" dimension
on the other side of the binding. Often one side will be properly
closed while the other is either insufficiently closed or overly
closed.
1. Do ADJ 1.11 Closer Chain Tension Adjustment
3.1.2

Element Insufficiently Closed

The element is considered under-closed if it is possible to pull a
sheet out of the twin loop binding by tugging on the end of the
sheet. An element is also considered under-closed if dimension "X"
above is less than 0.25 mm. The primary cause of under-closed
books is insufficient travel of the Closer jaws. To correct under-
closure, follow the steps below.
1. D0 GP 6.2.2 to access the CLOSING menu. Note the
current value.
2. Increase the value by one and exit the Settings Menu.
3. Run another set of books and re-measure the wire loop
overlap. If the new book meets the spec, return to normal
operation.
4. If the new book is still under-closed, repeat Steps 2 and 3.

3.1.3

Element Over Closed

The element is considered over-closed if Dimension X in the
diagram above exceeds 2 mm. An over-closed element may also
appear to be oval shaped, instead of round. The primary cause of
an over-closed book is if the Closer jaws travel too far during book
closing. To correct over-closure, follow the steps below.
1. DO GP 6.2.2 to access the CLOSING menu. Note the
current value.
2. Decrease the value by one and exit the Settings Menu.
3. Run another set of books and re-measure the wire loop
overlap. Visually inspect the loops to ensure that they are
round. If the new book meets the spec, return to normal
operation.
4. If the new book is still over-closed, repeat Steps 2 and 3.
