The conditions listed shown below can be a little complicated depending on where they are
observed. Special attention needs to be paid to the area where the problem(s) is/are noticed.
The Gfp 865DH does not have spring loaded rollers, they have a direct drive loading mechanism
which eliminates the problems that can be caused from pressure spring failures.
Heat rollers are pulling harder
in the center; add a little more
pressure
Heat rollers are pulling harder
on the edges; release a little of
the pressure
These two
conditions
are observed
from the
front of the
machine
where the
items are
being fed into
the heat
rollers
These two
conditions are
observed from
the rear of the
machine
where the web
is exiting the

The nip pressure is off on either the left or the right side of the machine. A nip adjustment
needs to be performed on the pull rollers, see
