Adj 1.2 Element Slack Detection Adjust - GBC eWire Service Manual

ADJ 1.2 Element Slack Detection Adjust

Inspection Procedure
Perform this procedure if the element slack detection mechanism within
the element feeder is too sensitive or not sensitive enough.
Symptoms of too sensitive:
1) Slack detection responds quickly to presence of element, yet the
mechanism does not rise quickly after element is removed.
2) Slack mechanism does not rise at all after removing element.
Symptoms of not sensitive enough:
1) Slack detection mechanism does not immediately move down
after contact with smallest element size, A (1/4").
2) When operating properly, the machine should feed additional
element and detect slack 3 or more times during creation of each
11" or A4 size element. If this does not occur then the device is
likely not sensitive enough.
Adjustment Procedure
1) Remove the covers shown in Fig 1. Refer to REP 3.1 for more details
on accessing the Slack Detect mechanism.
2) Loosen the M3 screw to move the weight right or left to increase or
decrease the sensitivity setting.
3) Check the setting after each adjustment.
a) Make certain that after depressing the slack detection mechanism
and then releasing it that the device immediately returns to the up
position. The device should not hesitate in returning to the up
position.
b) Using an (A) size element (1/4"), ensure that the device is
sensitive enough to immediately detect the weight of this smallest
element (detect slack present).
c) You can use GP 6.3.6, Functional Tests: Feed Element to help in
troubleshoot the element feeding process.
4) Reinstall the two covers shown and test the machine using the (A)
size (1/4") element while ensuring that slack is produced at least 3
times per feed of an A4 or 11" element.
