Description
The Keltron LC series is a rugged printer packaged in a metal enclosure ready to panel mount or use on
the desktop. This model features compact reliable, plain paper dot matrix impact printers capable of
printing from 12 through 32 columns per line (Keltron LC24s) or 15 through 40 columns per line (Keltron
LC40s).
The Keltron LC series printer supports the RS232C serial communication handshake. The Keltron LC series
also features user selectable print features and a 2000 character print buffer to free the host computer
during the printing process.
The basic Keltron LC series printer is comprised of a microcomputer-based printer controller card, a printer
mechanism module, a power supply with an interface card and a metal enclosure. The printer controller
and the printer mechanism are located behind the front panel. The rear panel holds the interface
connectors and the power supply module.
The Keltron printer controller and interface cards manage all the features supported by the printer. The
boards hold the printer drivers, communication interfaces, real time clock, line counter, interval timer
output, 2K print buffer and the front panel switch inputs. These enhanced features ease the operation and
integration of the printers with data acquisition applications.
Upon initial power-up, the printer controller goes through extensive self-test procedures. It verifies the
amount of print buffer installed and restores the default printer settings.
In the idle mode, the printer continuously checks the front panel controls and the paper out detector. It also
services the time clock, interval timer, print buffer, internal processor and the power supply watchdog
monitor.
Unpacking the Keltron LC Series Compact Printer
Remove the Keltron LC series printer from the shipping container and make sure it is undamaged. The
package also includes an AC/DC power adapter or a power input plug, a ribbon cartridge as well as a roll
of paper. If any of the components are missing, contact Keltron for assistance.
Keep the packing material so you can repack the printer for storage or shipment. If there is any visible
damage to the printer, record it on the freight bill, have the freight carrier acknowledge it and submit your
claim to the carrier.
