4-3 Detailed Descriptions of Cutting Conditions
Cutting quality is affected by the blade and media being used, and by the cutting conditions. There are four cutting
conditions: cutting speed, blade force, blade offset, and amount of blade extension. For high-quality cutting, it is neces-
sary to set the appropriate cutting conditions for the blade and media in actual use. Repeat cutting tests and adjustments
to the cutting conditions until the cutting quality for the media improves.
This section describes how to use the results of cutting tests to check the cutting conditions.
1
Peel off circle 1 (indicated by ).
• When it can be peeled by itself, without disturbing rectangle 2
(indicated by
), the blade force is set appropriately.
• If it peels, the setting for either the blade force or the amount of blade
extension is insufficient.
• If uncut areas remain in some places, the cutting speed is too fast.
2
Peel off rectangle 2 (indicated by ).
• The optimum blade pressure (blade force) is correct if you can clearly
make out the lines left by the blade.
• If the blade trace is indistinct or too strong, you need to adjust the blade
force or the amount of blade extension.
3
Check the shape of rectangle 2.
• If the corners are cut fully and properly as shown in A, the conditions
are correct.
• If the corners are rounded as shown in B, the setting for blade offset
is insufficient.
• If the corners have "horns" as shown in C, the setting for blade offset
is too large.
• If the cut shape is distorted, the cutting speed is too fast.
Check the points described above, and if the cutting quality of the media is less than good, adjust the cutting conditions.
For information on how to perform a cutting test and adjust the cutting conditions, go to "3-1 Points to Check Before
Performing Output" and refer to "Checking the Cutting Condition Settings," and refer also to "6-2 Detailed Descriptions
of the Menus."
Adjusting the Blade Extension
When you want to perform accurate and fine adjustment of the
cutting-in amount, such as when cutting media with thin carrier
paper, you can obtain good results by adjusting the tip of the blade.
Turn the cap portion of the blade holder to adjust the amount of
blade extension.
A change in extension of 0.5 mm can be made by rotating the cap
one full turn.
Note that making the amount of blade extension too small may
cause the end of the cap for the blade holder to touch and damage
the printed surface. It's important to be especially careful about
this when you're using media that has poor ink-adhesion proper-
ties.
Rough Estimate for the Amount of Blade Extension
Use the following dimension as a rough estimate for setting
the amount of blade extension.
