Hole Quality; Hanging Chad; Holes Are Not Cleanly Cut; Oil On Paper - GBC StreamPunch Ultra Service Manual

3.3 Hole Quality

There are three different Hole Quality problems:
•

Hanging Chad

•

Holes are not cleanly cut

•

Oil on Paper

3.3.1 Hanging Chad
This is caused when the clearance between the pin and hole in a
die-set increases.
Do GP 6.1.8 Die Cycles Procedure to check the number of cycles
for the installed Die Set.
If Die Set cycles have exceeded 750,000, replace the Die Set with
a new one.
3.3.2 Holes are not cleanly cut
This is usually caused due to lack of lubrication in the die-set. Do
GP 6.7.3 Die Set Lubrication.
If lubricating the die set does not fix the issue, replace die-set.
3.3.3 Oil on Paper
After a die-set is lubricated the next 25-50 sheets will come out with
oil around the punched holes. Running test sheets is
recommended until oil marks cease to appear.
