CHAPTER 6: Troubleshooting
6.1 First Steps
If the High Speed COS-2 does not seem to be passing data or switching
correctly, the first thing to try is to have the COS-2 perform its self-test as
described in
Section 5.3
. If the LEDs fail to light, contact your supplier. If
the COS-2 passes its self-test, check the settings of its DIP switches and
make sure these are correct. If they are, check the cables connected to the
COS-2 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-2 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.
