1.3 Major Components
The major components of the LG31 printer are:
• Control panels
• Printer mechanism
• Electronics
1.3.1 Control Panels
The printer has two control panels: the outer control panel and the inner
control panel.
The outer control panel is on the outside of the top cover. It has keys
for selecting normal operating functions and view window to the 3-digit
display (seven segments each), which is a part of the inner control panel.
The inner control panel is below the top cover and is used for detailed
operating functions such as:
• Running self-test
• Paper movement
• Resuming printing after fault clearance.
• Setting the printer configuration.
• Printing test patterns for printer alignment/adjustment.
The top cover should be raised to its highest position to defeat the top
cover interlock before the inner control panel can be used.
Associated with the inner control panel are an audio alarm for power-
up/fault detection and an initialization switch that erases the current
configuration settings and restores the printer to factory settings. See
Appendix B of this manual for a list of all the display codes.
1.3.2 Electronics
The electrical interfaces consist of the host communication port and the
ac power inlet. The mechanical interfaces consist of the platen gap, the
paper tension adjuster, the paper path tractors, ribbon cartridge, and the
outer/inner control panels.
