Introduction
The AT-1 / AT-1smartprint is designed for easy use and service: the service philosophy of
the AT-1 / AT-1smartprint is module replacement and not board repair. The purpose of
this chapter is to provide fault-finding procedures that will quickly and efficiently identify
a fault to a specific module. Fault-finding procedures are designed so that test equipment
is kept to a minimum.
An initial fault diagnosis chart is provided detailing general fault indications. Use the
procedures on the following pages to indicate a faulty area or module. In most cases
the fault diagnosis chart should indicate the most likely faulty area. When more than
one module is stated, the first module given is the one most likely to contain the fault.
Other modules given should be checked in the order given. When a module has been
replaced, specific test parameters and setting-up of the module may be applicable.
The removal and replacement instructions for all replaceable modules, along with any
setup or check procedures required, are given in Chapters 4 and 5.
If the initial fault diagnosis chart does not indicate the area where the fault exists, re-
check all the settings and parameters that have been entered.
