7.1 LED Status Indicator
This chapter describes normal operation of the NIC in the printer, and also provides information on how to troubleshoot any problems you might have with the NIC.
7.1 LED Status Indicator
The NIC has two LED status indicators: amber and green. The amber LED generally indicates job activity; it flashes when a print job is being communicated to the NIC; it is off when no activity is occurring.
The green LED indicates the operating condition of the NIC when it is powered on during normal operation. The following table provides the conditions that this LED may indicate.
