Information
To make the square spine of the book, pressure is applied to the
spine. This process is called forming.
Touch FORM to specify the amount of spine form.
To make a good spine on different paper types, the amount of
spine form can be changed.
To change the amount of spine form:
• Touch NUMBER to change how many times the spine is pro-
cessed
• Touch PRESSURE to change the pressure
Touch AUTO to select the optimum amount of spine form, accord-
ing to the set thickness.
Touch NUMBER to select how many times the form roller process-
es the spine. The available options are 1, 2, 3 or 4. An increase in
NUMBER increases the time taken to form the spine and can de-
crease the production rate for thin books. Alternatively, increase
the PRESSURE.
Touch PRESSURE to increase or decrease the pressure used to
form the spine.
Touch + to increase the amount of spine form. Touch - to decrease
the amount of spine form. The range is -9 to +9. The default set-
ting is 0.
Use THRESHOLD to choose whether a square spine is formed.
If the SET THICKNESS value is thinner than the THRESHOLD val-
ue, a square spine is not formed.
If the SET THICKNESS value is thicker than the THRESHOLD value,
a square spine is formed.
If the SET THICKNESS value is 1.5 mm or thicker, a square spine is
always formed.
The default value is 0.8 mm. The allowed range is 0.1 mm to 1.5
mm
The trim dimension is calculated automatically according to the
PAPER SIZE and SET THICKNESS.
If needed, the trim dimension can be changed. Touch TRIM to ad-
just the size of the finished book after the fore-edge is trimmed.
The maximum trim is 28 mm. The trim function can be turned off.
Touch AUTO to select the default trim position.
