CHAPTER IV TROUBLESHOOTING
4.1
Overview
This section gives the service personnel some of the troubleshooting procedures to
be followed if an error or malfunction occurs with this machine. It is impossible to
anticipate all of the possible troubles which may occur in future and determine the
troubleshooting procedures, so this chapter covers some sample troubles. However,
those samples will help service personnel pinpoint and repair other defective
elements if he/she analyzes and examines them well.
4.1.1 Precautions
Be sure to observe the following precautions to prevent the secondary problems from
happening during troubleshooting:
(1) Get a good idea of what the trouble is. Whenever more than one trouble source is
found, plan the most reasonable repairing procedure after reviewing the
relationship between them.
(2) When supplying power to this machine having problems from either a set of dry
cells or the optional AC adapter, make sure that its output voltage level is 8 to
13V under no load.
(3) When supplying power from a stabilized power unit, use the power unit with
approx. 3A capacity and choose the output level of 8 to 13V. When connecting it
to this machine, be careful with the polarity.
(4) When using a circuit tester for testing the conductivity, remove all of the dry cells
and the AC adapter from this machine.
4.1.2 After Repairing
After repairing the defective section, be sure to check again (Refer to “3.2 Final Check
and Inspection Mode”.) to see if the repaired section works correctly. Also make a
note of the troubleshooting procedure so that it will be handy should problems occur
in the future.
