Limitations - GBC Quantum P70iX Manual De Uso

2. Getting to Know your Quantum P70iX

LIMITATIONS

To ensure your satisfaction, please take a moment to understand the following
application limitations.
• Tabs must have a 1/4" shoulder. Without this shoulder, the paper lift cannot
be properly tapped into the punch die, resulting in poor hole registration.
• When running mixed stocks, you must ensure the dimensions are consistent.
One stock smaller than the other will prevent proper hole registration.
• Very slippery paper or cover stocks may not run in the P70iX. Test small stacks
at slower speeds and/or smaller lift sizes before committing to a large job.
• Cover stocks mixed with paper usually run best at slower speeds.
• If a very straight output stack is important for a particular job, select speed
one or two for improved stack quality.
• When running cover stock alone, performance is best at slower speeds.
• Improper loading of stack will result in feeding problems. Take care to justify
the stack against the input door and the right stacking registration bracket.
• Some specialty papers (NCR paper for example) will show handling marks.
• The punched edge of a stack will be taller than when it went in. With some
papers, paper sizes and die set combinations; you may want to reduce the
input stack to prevent slumping, instability or excessive height.
• Excessive paper curl can result in poor feeding or jams. You can identify
excessive paper curl when you see more than 1/4" of curl 2" from the paper
edge. If curl is not excessive, you will have best results with the curl down.
For our purposes, curl down is defined as the outside front edges are down
and the middle is up.
