Aligning the Printing Length and Cutting Length
There is normally no need to adjust this. When there is no effect due to expansion or contraction of the material, use with the calibration
value always set at “0.”
However, when printing is followed by cutting, the cutting length may be displaced from the printing length.
This is because the material may absorb moisture from the ink or the air, making it expand or contract. The degree of expansion or
contraction varies depending on the composition of the material, the composition of the base paper, and the temperature and humidity
where installed. In general, highly absorbent materials are more susceptible to expansion and contraction.
At such times, use the display menu’s [CALIBRATION_CUTTING ADJ.] function to adjust the cutting length with respect to the
printing length.
The calibration value that you set persists even after the power is switched off. After performing output, return the calibration value to
“0.”
When you have set a base point, and have set an align point on the upper-right crop mark, the machine automatically adjusts the
length for printing and cutting. At this time, the correction value in this section is ignored. For more information, take a look at
"User's Reference - Removing Printed Material, Then Reloading and Cutting."
To calculate the correction value, measure the lengths of A, B, C and D in the following diagram. 1

* If the cutting line is in the "+"
direction from the printing position,
then input the correction as a "-".
If the cutting line is in the "-"
direction from the printing position,
then input the correction as a "+".
