Accurately Adjusting The Misalignment Of The Ink Landing Position - Roland TrueVIS MG-640 User Manual

Using the Correction Functions

Accurately Adjusting the Misalignment of the Ink Landing Position

This adjusts the landing position of the ink discharged from the print heads. You can make adjustments
more accurately than "MEDIA GAP ADJ SIMPLE SETTING". The landing position varies according to the print
head height and the thickness of the media, so we recommend that you make corrections to match the
media you are using.
First, print a test pattern, and then determine and enter the correction value. After entering the correc-
tion value, print a test pattern again and check the correction results.
This adjustment must be performed in the following cases.
• When using this machine for the first time
• When changing the media to use
• When you have changed the print-head height
• When printing does not improve with "MEDIA GAP ADJ SIMPLE SETTING"

View the printed test pattern, and then determine the correction values from "MEDIA GAP ADJ. No.1" to
"MEDIA GAP ADJ. No.4".
Select the value that gives the least misalignment between the two lines. In the case of the fol-
lowing figure, select "+5" for NO. 1. When you cannot choose between two sequential numbers, se-
lect a value that is between them (you can set correction values in units of "0.5").
