5.6 Diagnostic Functions
The printer diagnostic functions are Self-Test page, hex-dump mode and print alignment
adjustment.
•
Self-Test page: 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 MODE: 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.
•
PRINTING ALIGNMENT ADJUSTMENT: Allows you to check and, if necessary, correct
the printer’s vertical line print alignment in bi-directional mode.
