About the Printer
The LG
plus
Series is a family of line matrix printers: The LG04
plus
prints at a
maximum rate of 475 lines per minute (lpm). The LG08
plus
prints at a
maximum rate of 800 lpm, and the LG12
plus
has a maximum print rate of
1200 lpm. Each model is housed in a quiet floor cabinet. These rugged and
reliable line printers represent the state of the art in line matrix printing
technology.
LG
plus
Series printers feature a flash memory architecture that permits rapid
access to stored printer emulations. All models use a variable–speed shuttle,
half–step paper feed control, and system architecture contained on a single
circuit board, enabling them to print high–volume jobs with minimum
maintenance, maximum reliability, and an impressive variety of print
options.
Although technologically advanced, LG
plus
Series printers are easy to use.
The user can select every printer function at the control panel or by sending
printer control codes in the data stream from the host computer.
Important Maintenance Notes
To maintain optimum printer performance, remember these important
maintenance concepts when you service the printer:
♦ Use only the ribbons specified in Appendix B. Use of incorrect ribbons
can lead to ink migration problems, degraded print quality, and expensive
damage to the printer.
♦ Incorrect closure of the forms thickness lever can lead to smearing,
degraded print quality, paper jams, and damage to the platen and shuttle
assembly. Never close the forms thickness lever too tightly.
♦ The hammer springs and hammer tips on the hammer bank are extremely
delicate and precisely aligned. Never bend or tweak hammer springs and
always handle hammer springs by the thick mounting base of the fret.
♦ Do not adjust the platen gap unless a new shuttle frame assembly or
platen was installed.
