Checking connections
The most common causes of hardware problems are faulty or loose connections. This
section describes internal connections from the copier to the Fiery AR-PE2, external
connections on the Fiery AR-PE2, and internal connections in the Fiery AR-PE2
assembly.

2.
Inspect internal ribbon cables to see if they are intact.
Faulty ribbon cables are easily overlooked. Check the contact point between the cable
and the connector to ensure that they have not separated. If a ribbon cable is suspect,
substitute it with a tested cable.

Service Procedures
Verifying connection to the network
The Fiery AR-PE2 provides twisted pair connectivity to an Ethernet network. This
section describes how to connect the Fiery AR-PE2 to the network and print a few test
documents in order to verify the connection.

Service Procedures
Verifying the parallel port connection
On the Fiery AR-PE2, the parallel connector (female 36-pin mini-Centronics) provides a
high-speed interface port for connecting directly to the parallel port of a PC. The parallel
port can be used for installing system software (see page 3-20).
