C3400n User’s Guide
Printer status (as indicated by the LEDs) can be broadly
categorised as follows:
1.Normal status (Green): the printer is operating normally e.g. it is
ON LINE or processing.
2.Warning status (Amber): you can continue to use the printer
without intervention but an error may result.
3.Error status (Amber, blinking): you cannot continue to use the
printer. Intervention is required to recover from the error. Fatal
errors are irrecoverable and require a service call.
When several different status situations occur concurrently,
only the status with the highest priority is displayed on the
LEDs. Warning status combined with the highest-priority
normal status is displayed on the LEDs.
A summary of the functions of each LED is given below:
