3 CALIBRATION
If correction with "2 HEAD ADJUST" is done and there is still an offset between the printing and cutting positions, use the following
correction method.
Measure the sheet offset caused by expansion/contraction and store it in the CJ-70/60.
Because different sheet materials have different offsets, either reset the value when using a different sheet material, or use "1 CROP
MARK" to make the adjustment.
This is suitable to places when variation in ambient temperature and humidity are low, and sheets of a single material are used. The
setting will not be erased even if the power is turned off.
