Level 1 Diagnostics
Level 1 Diagnostics (setup mode) allow you to change the settings for various
printer functions (described on the following pages) and to run certain tests
using the DIP switches.
Keep the following information in mind when changing the settings:
• 
Turn the power off (not required, but recommended): press the On Line
button (although the printer still receives power, this is sufficient for
changing the DIP switches)
• 
The settings can only be changed when the printer is in level 1 diagnostics
(setup mode): switch 1 must be set to On.
• 
Turn the power back on. The printer beeps, and the On Line light (green)
blinks.
• 
Once the settings have been changed and stored in the EEROM, the DIP
switches must be set back to the on-line settings for the printer to operate.
• 
The stored settings for the functions are printed with a dump of all resident
characters during a print test. See “Testing the Printer” on page 23.
• 
The default settings are set at the factory and are stored in the history
EEROM.
Caution:
  If you change the switch settings, be sure they are the correct settings
for that particular function or test to avoid accidentally changing the settings for
another function or test. If the settings are accidentally changed, use the switch
settings shown in the tables throughout this section to change those settings back.
If you need assistance, contact your service representative.

•
