3.4 Element Roundness
3.4.1 Theory of Operation
For good roundness to be achieved, the tips of the element wire must
be in contact with the rear face of the Closer during closing operation. If
the wire tips are skewed or offset from the wall prior to closing, poor
roundness can occur.
3.4.2 Troubleshooting Steps
1. Roundness problems can be caused by an over-closed element. If
it seems that the Element may be over-closed, refer to the steps in
3.1 correct it.
2. Confirm that you are not sending too many sheets. Try sending a
book with the number of sheets indicated in Section 3.3.2, Step 2.
See if the problem still occurs.
3. Check the printed sheets for excessive curl. If the curl is too large,
eWire will be unable to properly process the sheets. If necessary,
adjust printer settings to reduce curl.
4. Roundness problems can also occur if all sheets on the book are
not hooked properly. If there are both hooking and roundness
issues, refer to the steps in 3.3 to correct the hooking issues
before proceeding to the next steps.
5. If the surface on the Closer jaws appears to be worn, replace the
closer jaw insert plates.
6. While making a book, watch the machine carefully, and open the
top cover after the Holder has transferred the element to the
Closer, but before the close cycle is completed. By doing so, you
should be able to look from the front and back to identify if the wire
tips are not touching the back wall of the Closer.
7. If you are experiencing roundness issues with F size elements,
perform ADJ 1.24 F Size Mac Capacity Closer Adjustment
8. If the element tips are not touching the back wall of the Closer, it is
possible to increase the distance the Closer travels to pick up the
element from the holder. Do GP 6.1.6 to adjust the Closer to
Holder value and increment by 10.
9. If incrementing the Closer to Holder value by 10 made a small
improvement but it is still not round, try incrementing by an
additional 10. If incrementing the value made the problem worse,
try a -10 adjustment from the original value.
10. Repeat Steps 6-8 to identify the best possible value for Closer to
Holder value.
11. If the element appears to be angled prior to close (See pictures in
3.4.1), it may be necessary to adjust the Holder horizontal position.
Refer to ADJ 1.9 for instructions on how to adjust the Holder.
