Liquid Crystal Display (LCD)

The liquid crystal display (LCD) displays printer status, messages, configuration options, and error codes.

Status Indicators

The status indicators display the current operational status of the printer.

LINE SYNC

Twinax interface only. Indicates there is activity on the line from the host computer.

SYS AVAIL

Twinax interface only. Indicates there is activity to the current address on the line.

JOB IN PROCESS

When the printer is receiving data or processing data, JOB IN PROCESS flashes. If data has been processed and is waiting to be printed, or has been printed but not yet fused and ejected by the printer, JOB IN PROCESS lights continuously.

JOB IN PROCESS does not light when the printer is not processing data, no data exists in the buffer, and the printer is not receiving data.

STAND BY

IMPORTANT Do not press any control panel key when STAND BY is flashing. The printer may carry out unwanted commands.

STAND BY flashes while the printer is executing any control panel command, and while the printer is unavailable for printing due to its normal system activities, such as booting, printing its configuration, writing status information, and loading applications.
