This chapter focuses on the troubleshooting process, identifies the source of common 
problems that may occur with the Fiery AR-PE2 assembly, and suggests ways of 
correcting them.

The troubleshooting process is designed to eliminate the most obvious causes of failure 
before progressing to more complex issues. “Where problems occur” on page 4-2 gives 
an overview of the Fiery AR-PE2 components and indicates areas most likely to require 
troubleshooting.

If the Fiery AR-PE2 fails to complete its Start-up sequence and the copier does not reach 
Info, the most likely cause is a loose cable or board connection. See “Checking 
connections” on page 3-3. 

• Try a phone check before you go to the customer site.

“Before you go to the customer site” on page 4-3 suggests areas you should check 
out before making a service call to the customer site. With a phone call, you can find 
out if the problem is a simple operating failure or a failure caused by a network or 
configuration change. You can ask the customer to check for loose cables on the side of 
the copier and loose connections at a power strip or outlet. 

• Check for obvious causes of problems.

“Preliminary on-site checkout” on page 4-4 takes you through the initial visual 
checkouts you should make when you arrive at the customer site. You should check the 
Operation Panels for an error message and see if the LEDs indicate an error condition. 
Then inspect the copier externally and internally for the most common problems, such 
as loose or faulty cables.

• Check network connections.

“Checking network connections” on page 4-8 provides guidelines for checking the 
network connections between the copier and the computers to which it is connected, 
as well as information on several printing problems.
