Chapter 3  Troubleshooting

  LED Status Indicator

The KN-304 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 Print Server Card; it is off when

no activity is occurring.

The green LED indicates the operating condition of the KN-304 when it is powered on during nor-

mal operation. The following table provides the conditions that this LED may indicate.
