See “Accessinginternal components” on page 4-3 for instructions on opening the iR-M1, and “Check-ing internal connections” on page 4-8 for descriptions of iR-M1 parts and connections.If a loose part or cable is not the cause of the problem, see “Checking the iR-M1 as astand-alone unit” on page 5-8, and “Checking the entire iR-M1 system” on page 5-14.• Try a phone check before you go to the customer site“Before you go to the customer site” on page 5-3 suggests areas you should check outbefore making a service call to the customer site. With a phone call you can find out ifthe problem is a simple operating failure or a failure caused by a network or configura-tion change. You can ask the customer to check for loose cables on the back of the iR-M1 and loose connections at a power strip or outlet.• Check for obvious causes of problems“Preliminary on-site checkout” on page 5-5 takes you through the initial checkout youshould make when you arrive at the customer site. You should check the iR-M1 inter-nally and externally for the most common problems such as loose cables, connectors,and boards.• Check the iR-M1 as a stand-alone unit“Checking the iR-M1 as a stand-alone unit” on page 5-8 describes the checks youshould perform on the iR-M1 if the initial checks fail to identify the cause of a problem.With the iR-M1 disconnected from the copier and the network, test the iR-M1 as astand-alone unit.This section describes possible startup errors and explains how to run and interpret iR-M1 diagnostics.• Check the entire iR-M1 system“Checking the copier interface” on page 5-14 explains how to print the Test Page fromthe iR-M1. “Checking network connections” on page 5-15 includes guidelines forchecking the network connections between the iR-M1 and the computers or workstationto which it is connected, and also provides information on several printing problems.
