2. Select the SELF-TST function.
Repeatedly press the LOAD button or the LF/FF button to position
the red cursor under SELF-TST, and then press the MENU button or
the TEAR OFF button. The printer selects SELF-TST and starts
printing. A short help menu is printed at the top of the page,
followed by the self-test. Note that the printer is not online during
self-test printing.
3. Examine the self-test page.
A sample self-test page is shown in Chapter 2. To pause during self-
test printing, press the MENU button or the TEAR OFF button. To
resume self-test printing, press the FONT button or the MENU
button again.
4. Exit the SELF-TST function.
Exit the SELF-TST function in either of the following ways:
• To exit SELF-TST and remain in setup mode, press the LF/FF
button. The <> menu is then reprinted.
• To exit SELF-TST and return online, press the ONLINE button.
The printer permanently saves any changes made while in setup
mode and returns online.
The self-test can also be started by turning off the printer, and then pressing
the LF/FF button while turning the printer back on. As described in Chapter
2, this method is useful when you first set up the printer.
Printing Hex Dumps
The HEX-DUMP function prints data and commands in hexadecimal
characters and abbreviated control codes. The IBM character set 2 is used
for printing (see Appendix E). The HEX-DUMP function is useful for
checking whether your computer is sending the correct commands to the
printer and whether the printer is executing the commands correctly. It is
also useful for debugging software programs.
