Unsupported flash option
Service codes
All service errors are indicated by all lights flashing as the primary notification or code. The secondary light
pattern indicates an area or function which has the error. Tertiary codes (shown on the following pages) indicate
specific device errors. When all lights flash, double-click to see the secondary code. Double-click again to
see the tertiary code. Double-click a third time to return to the primary light pattern.
In the following example:
• The primary light pattern indicates a service error (all flashing). Double-click for more information.
• The secondary light pattern indicates a fuser, toner sensor, or fan error. Double-click for more
information.
• The tertiary light pattern indicates the fan has stalled. Double-click again and the original primary light
pattern will appear.
Note:
• The printer cannot directly determine that a fan has failed, but can sense the higher temperature at the
fuser or printhead.
• If data is sent to the printer and all lights flash simultaneously, and double-clicking does not produce a
secondary code, there may be a code problem. Contact the next level of support.
