DIAGNOSTIC
FUNCTIONS
GETTING HELP
User's Manual
The printer diagnostic functions are SELF-TST, HEX-DUMP, and
V-ALMNT.
• SELF-TST tells you whether the printer hardware is functioning
correctly. If the printer hardware is functional, any problems
you are having are probably caused by incorrect printer
settings, incorrect software settings, the interface, or the
computer.
• HEX-DUMP allows you to determine whether the computer is
sending the correct commands to the printer, and whether the
printer is executing the commands correctly. This function is
useful to programmers or others who understand how to
interpret hex dumps.
• V-ALMNT allows you to check and, if necessary, correct the
printer's vertical print alignment.
For details on using these functions, all of which are available in the
printer setup mode, see the section Using the Diagnostic Functions in
Chapter 5.
If you are not able to correct a problem using this chapter, contact your
dealer for assistance. Be prepared to provide the following informa-
tion:
• Your printer model number, serial number, and date of
manufacture. Look for this information on the rating label on
the left side of the printer.
• Description of the problem
• Type of interface you are using
• Names of your software packages
• List of the printer default settings. To print the default settings,
see the section Printing a List of Selected Options in Chapter 5.
