Xerox EX7750 User Manual

This chapter provides troubleshooting tips.

Startup diagnostics are described in the Installation and Service Guide for service 
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. 

The following section explains some error and alert messages you may see during Setup 
that may not be self-explanatory.

Enable AppleTalk
(Network Setup>Protocol 
Setup>AppleTalk Setup)

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 
EX7750 before performing AppleTalk Setup.
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.

Protocol Setup or Service 
Setup (Network Setup)

You must first enable
a network port.

Enable at least one network port (Ethernet) in Port Setup 
before beginning Protocol Setup or Service Setup.

Frame Type selection
(Network Setup>Protocol 
Setup>IPX/SPX Setup)

Invalid frame size.

The network hub is not connected to a Novell server when 
the EX7750 tries to bind.

Warning! IPX network
number is zero.

No other IPX machine can be found on the network, or 
the network hub is not connected to the network when the 
EX7750 tries to bind. When this occurs, the network 
number defaults to zero.
