CHAPTER 5: Operation
6.1 First Steps
If your High Speed COS-4 or High Speed COS-8 does not seem to be
passing data or switching correctly, the first thing to try is to have the COS
perform its barber-pole self-test as described in
Section 5.3
. If the data that
the COS is transmitting looks OK, check the settings of its front-panel Mode
switch and its internal DIP switches and make sure these are correct. If they
are, check the cables connected to the COS and make sure all of them are
securely connected to the proper equipment at both ends. If the cabling is
OK, turn the printer(s) off and back on and try again. If problems persist,
reboot the computer(s) (saving any documents in progress first), reload the
software you were using and the affected document(s), and try again. If you
still have problems, contact your supplier.
6.2 Calling Your Supplier
If you determine that your High Speed COS-4 or COS-8 is malfunctioning,
do not attempt to alter or repair it.
Contact your supplier. The problem might
be solvable over the phone.
Before you do, make a record of the history of the problem. Your
supplier will be able to provide more efficient and accurate assistance if you
have a complete description, including:
• The nature and duration of the problem.
• When the problem occurs.
• The components involved in the problem.
• Any particular application that, when used, appears to create the
problem or make it worse.
