If “FINE” has been selected )
”FINE” is used to check, or perform fine adjustment of, the X PRINT, Y SINGLE, Y REPEAT,
and Y BI-D correction values. Accordingly, perform the “FINE” after the X PRINT, Y
SINGLE, Y REPEAT, and Y BI-D corrections have been performed.
•[FINE] is used for dot position fine adjustment and [FINE: FINAL] is used for dot
position check. [FINE: FINAL] cannot be used for adjustment.
• Adjust the shot so that the pattern (Y SINGLE, Y REPEAT) for dot position
correction [FINE] totally be as uniform as possible.
[ Example of Y SINGLE, Y REPEAT, and Y BI-D adjustment ]
For V2 and N2, change of the correction value of 1.0 results in a shift of about 35µm. For V1
and N1, it results in a shift of about 70µm. When using a scope, note that vertical and horizontal
inversions occur.
With Y BI-DIRECTIONAL / FINE, the above pattern is plotted only in black.
• Make adjustment so that other lines be
overlapped with the HEAD1 (Black) line as
closely as possible. However, the most important
is overlapping of HEAD1 and HEAD2, HEAD3
and HEAD4, and HEAD5 and HEAD6.
• Adjust the correction value so that dot shift at
left, right, and center positionsa totally be as
uniform as possible. (Do not adjust it by noticing
only one point.)

When the dot position viewed from the scope is as
shown above, enter a positive value as the correction
value for HEAD1 and HEAD2.
