3.3 Sheets not Hooking

3.3.1

Introduction

The core function of eWire is the hooking of punched sheets onto a
wire loop, and then closing the wire loop to create a bound
book. This section will lay out the troubleshooting steps for
when sheets are not accurately being hooked on the twin loop
wire tips.
A problem with hooking will result in poor book quality. In some
cases, it will also create a Jam code. J244 (Sheets left in stack
area) or J202/J203 (Stay Jam Area 2) are the most likely Jams
to be caused as a result of poor hooking.
Note that there are multiple Jam codes that could be triggered by
an unsuccessful hooking operation. If a Jam code is repeatedly
seen that does not have an obvious root cause, following the
steps in this section may help lead to a resolution.

Troubleshooting Steps

Follow the procedure below to correct a 'not hooking' issue on
eWire. If a change to eWire is made as a result of one of the
troubleshooting steps below, run additional books to determine if
the change has resolved the problem.
1. Verify that the eWire is properly docked to the upstream
device and that there is no misalignment between the
devices. Confirm that the sheets being fed into the eWire
are aligned with the sheet location marks on eWire.
Refer to Section 8 Installation for more detail.
2. Check the printed sheets for excessive curl. Refer to
Section 3.5.2. If the curl is too large, eWire will be unable
to properly stack and hook the sheets. If necessary,
adjust printer settings to reduce curl.
3. Do the steps in Section 3.2 to verify that the punched
holes' positions are accurate and precise and that the
holes are punched cleanly.
4. Poor hooking can occur when the sheet quantity is too
high or paper stock is too heavy or too light. Refer to
Section 3.5 for the maximum allowable number of sheets
in each element size and allowable media.
5. Do GP 6.4 to check S3, S18, and S19
GBC eWire
6. Do GP 6.5 to check M5 to M7
7. Do GP 6.6 to check L5 to L8
8. Install a new, unopened spool of the same size element.
If this solves the issue, visually inspect the wire on the
spool that was removed for damage or defects; refer to
Section 3.3.3.
9. Do ADJ 1.8 to verify the Deflector timing and eWire
Alignment and Skew settings.
For steps 10 to 13, if a change is made, ADJ 1.8 will
need to be repeated to correct the Deflector timing and
eWire Alignment and Skew settings.
10. Do the steps in ADJ 1.3 to verify the mating of the
Holder module to Element Feeder. The Holder and
Element Feeder should mate together smoothly, with no
gap between the faces.
11. Visually inspect the Holder Rotate Linkage. Ensure that
no parts in the linkage are damaged, loose, or bent.
Refer to ADJ 1.9 for info on checking the Holder Rotate
function.
