Shifting amount of the lower lines
The following illustrates and explains the shifting amount of the lower lines
printed on the pattern assuming that the shift amount is “x” micrometers when
the paper thickness is changed by 0.1mm.
Figure 1-23. Shifting Amount of the Lower Lines on the Pattern
Note : AB: Gap adjustment value when paper thickness is +0.1mm
AC: Present gap adjustment value
AD: Gap adjustment value when paper thickness is -0.1mm
Given that the gap regularly corresponds to the change in paper thickness;
X* = AC - AB = AD - AC
* The “x” value is 240 cps or 14.42 micron meters in VSD2 mode.
The value is saved on the NVRAM, and is left changeable.
Example) Gap adjustment when paper thickness is 0.2mm
