5.2 Adjustment
This section explains the specific procedures for making the
adjustments using the exclusive adjustment program for Stylus Color
640/660.
5.2.1 Adjustment by Adjustment Program
For this printer, it is necessary to set the correct information for each
printer mechanism in order to maintain consistent printing function and
quality, eliminating differences among each printer mechanism's
characteristics.
Therefore, in case that the combination of the printer mechanism and
main board changes or the printhead is replaced during repair, you
must set and save the correct information to the main board, using the
exclusive adjustment program.

5.2.1.1 About Adjustment Program
The adjustment program (Program name: Stylus COLOR 600 640 660)
enables you to set various values correctly to prevent malfunction and
fluctuation of printing quality and printing function caused by difference
in components and assemblywhen the printer components are
replaced during repairs. Basic adjustment menu in this program are
shown in Figure 5-1. Options in the Program.
NOTE:This Adjustment Program can not be used in Windows NT
and Dos environment.
