HP DesignJets 500, 510 and 800 Series Printers Service Manual
Using the Formatter/Accessory Card LEDs to
Troubleshoot
In certain circumstances the LEDs located in the Formatter or HP-
GL/2 Accessory Card can help to highlight certain failures. There
are 3 LEDs, Red, Yellow and Green and using different
combinations can indicate different problems.
The yellow LED (normally flashing) indicates that the Formatter/
Accessory Card is alive. If it stops flashing, it means that the
Formatter/Accessory Card has failed and should be replaced.
The green LED indicates that there is power being supplied to the
LED’s on the HP-GL/2
The LED’s on the Formatter
can be seen without having to
remove the Left Hand Cover.
