Troubleshooting the EX7750

technicians. Contact your authorized service/support center if you see any startup error
messages on Command WorkStation or if the EX7750 does not reach the Idle state.
Troubleshooting during Setup from the Control Panel
The following section explains some error and alert messages you may see during Setup
that may not be self-explanatory.
Network Setup messages

No AppleTalk zone found. The Ethernet network cable is not attached to the
connector on the EX7750, or the network cable is not
plugged into the hub or network. If your AppleTalk
network has zones, and you want to specify a zone for the
EX7750, you must connect the network cable to the

This message could also mean the AppleTalk network does
not have zones. Zones are not required for printing to the
EX7750. Press OK to continue.
