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).
• Remote models: press the On Line button (although the printer still receives
power, this is sufficient for changing the DIP switches)
• Integrated models: turn the host computer off.
• 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
(remote models only).
• 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” in “Chapter 2: Installing the Printer.”
• 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.
The functions and tests are described in the following order in this section:
• Setting Data Error (RS-232C) and Data Buffer (RS-232C and Parallel) options
• Setting printhead resistance
• Setting default lines per inch
• Setting partial cut distance
• Setting the 7150 response mode
• Ignoring/using the carriage return
• Running the data scope mode
