5.5.2. ISSUE
: Element unclosed on one end
REASON / LOGIC :
This occurs when element is inserted too quickly on one
end into the bind throat causing it to push the element
over the element grip area on one side. The side that is
open is the area where the element is overfed into the
bind throat.
Root Cause Location Solution
Check element for bending
signs Binding elements Align the binding element and
let it sit against a straight edge.
If the element bends, please
inform GBC service help desk
and record batch numbers from
the element box.
Check to ensure tension
springs are attached on
both sides
Top left and right

Both springs should be
attached. Replace spring if
broken
Check split and push

Split and push fingers
should be at the same
level across
At the back end of the
machine If split and push fingers are not
level, remove and aligh them
against a flat edge. The split
and push fingers bend slightly
downwards at an angle but
should be level across.
How many cycles?
-
If over 15000 cycles ->
Check spine holder down
cam. Cam has life of
over 15,000 cycles
- wear can be detected if
there are golden
shavings under the cam
Spine holder cam is
between the large
white gears and the
frame on both sides of
the machine
If the spine holder down cam is
worn, gold shavings under the
