Both feeders 6 & 7 show Fault in Paper Tray Status
The help just says re-boot.
Both trays descend and ascend without error
I tried unplugging and re plugging in all cables but still the error
Any help wold be appreicated
Sounds like you have tried everything already, so it would require a service technician: please call 1-800-821-2797 to schedule a service call.
