Printer status (as indicated by the LEDs) can be broadly 

categorised as follows:

Normal status (Green): the printer is operating normally e.g. it is 
ON LINE or processing.

Warning status (Amber): you can continue to use the printer 
without intervention but an error may result.

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.
