5.2.2 Using the Adjustment Program

The adjustment program lets you set various values to compensate for
component manufacturing variations. It also lets you ensure that parts
are properly adjusted after completing repairs.

5.2.2.1 Operating Environment

For the adjustment program to run properly, your computer must be
configured as described below. Reboot the PC after making any
changes to enable the new settings.


Use MS-DOS version 6.2 or higher.


Start the adjustment program only after booting to DOS, as the
program does not operate in a DOS window within the Windows
environment.


Use only LPT1 as the printer port.


Check the contents of your CONFIG.SYS file, and add the following
command line if it's not already present:
Device=c:\<path name>\ansi.sys
Devicehigh=c:\<path name>\ansi.sys
The device driver ansi.sys enables escape sequence characters to
display properly on the screen. Replace <path name> with the path
of the directory containing your ansi.sys file. (If you're not sure
where the ansi.sys file is located, you can use the Find tool in
Windows Explorer to locate it.)


Check the contents of your AUTOEXEC.BAT file, and add the
following command line if it's not already present:
Mode lpt1:retry=p
This command resends failed transmissions of raster data, and
defines the numbers of retries to the printer port as permanent.
