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 information:
• The printer number is on the rating label on the right side of the
printer. The serial number and date of manufacture are on the label on
the rear 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.
