5.1 Troubleshooting
5.1.1 Repairs
a) Check installation environment
Check that the following conditions have been met with regard to installation environment.
(1) This fax must be installed on a level surface.
(2) Ambient temperature should be 50°F (10°C) to 90.5°F (32.5°C), with humidity from 20
to 80%RH.
(3) This fax should not be used in a location where there is ammonia gas emission, high
temperature and humidity (such as near water faucets, hot water heaters, humidifiers,
etc.), locations near fire sources, and dusty locations.
(4) Avoid exposing the equipment to direct sunlight. If necessary, instruct the user to use a
curtain to screen sunlight.
(5) Install in a well ventilated environment.
b) Check recording paper
(1) Only recommended recording paper should be used.
(2) Care should be taken with the storage of recording paper. Store the paper in
environmental conditions as close those in which the machine is being operated. In
particular, should the paper be subjected to high humidity, it will lose its rigidity and
making it liable to jam.
5.1.2 Precautions for troubleshooting
(1) Before starting any other troubleshooting, check that all connectors and printer cables
are securely connected.
(2) When effecting repairs with the outer cover open, and the power cord plugged into the
socket, exercise caution so as not to receive an electrical shock from the power supply
unit, or to short out the logic board.
(3) When you have finished troubleshooting, be sure not to forget any connectors, or to
leave any screws loosened.
(4) When you have finished troubleshooting, be sure to carry out a communications test to
ensure that everything is working properly.
