Adjusting The Blade Length - GRAPHTEC CUTTING PRO FC3100-60 Service Manual

3.4 Adjusting the Blade Length

Caution : Make sure to correctly adjust the blade length. If the blade length is too long for the thickness
of the medium being used, you may cut through the cutting mat and damage the plotter.
• Adjusting the Blade Length
• Obtaining the Correct Blade Length
Assuming that the film thickness is "t", the blade length "l" should be equal to "t". Make sure that "l" is
never greater than the combined thickness of the film and its backing sheet.
If the film thickness cannot be accurately determined, adjust the blade length by gradually increasing it
until only traces of the blade appear on the backing sheet when a cutting test is executed. For more
information about the cutting test, see USER'S MANUAL Section 4.7, "Running a Cutting Test ".
(1) Before adjusting the blade length, align the blade tip with the tip of
the cutter pen by turning the red or blue blade adjustment knob in
the B direction (see the figure below).
(2) Next, extend the blade tip to the length suitable for the medium to
be used by turning the blade adjustment length in the A direction.
Observe the scale on the plunger cap to determine how far to move
the blade.
When the knob is turned the distance of one scale unit, the blade
moves 0.1 mm. When it is given one full turn, the blade moves 0.5
mm.
a. To extend the blade, turn the knob in the A direction.
b. To retract the blade, turn it in the B direction.
