Paper quality and machine performance
Careful measurement of the paper size and set thickness is important in order
to produce good quality books.
• To make an accurate book you must enter accurate paper dimensions into
the touch screen.
• Measure the size of the printed paper. The paper dimensions change due to
shrinkage when the paper is printed.
• If the book is made from several different types of paper, make sure the
different paper types are all the same size. If the size of the paper is different,
an accurate book cannot be made.
• The paper must be cut accurately. If the sheets are not cut squarely, an
accurate book cannot be made.
Perform the following tasks:
Load the saved “A3 Test” job.

Make the book
Delete the saved job.
Load the saved “A4 Test” job.
A3 input size
Measure the paper from the stacker
Make the book
Delete the saved job.

Paper Path
It is important that the alignment of the PSQ and the printer is correct. This can
change if either the PSQ or the printer is moved accidentally.
Curly paper can sometimes cause the set to remain in the stitch area, causing a
jam. Paper curl problems must be resolved at the printer by changing or turning
the paper or making adjustment to the printer.
