8. Solving problems
Follow the procedures in this chapter if problems arise during the
operation of your LPS. If additional help is required, refer to the
card in the back of this book for instructions on contacting a
Xerox support service.
Aid to problem solving
If you have trouble identifying the cause of errors, you can log
the commands you enter and the system responses in a special
file using a function called the Data Capture Utility (DCU). If you
feel that this feature could be beneficial to your work on the
system, consult your system administrator or refer to the Xerox
4050/4090/4450/4650 LPS System Administration Guide.
9-track magnetic tape drive on the controller cabinet problems
In case you encounter magnetic tape drive problems, you can
take the following remedial steps to resolve the problem. For
further information, refer to the “Using the 9-track magnetic tape
drive” section of the “Setting up print job sources” chapter.
Responding to 9-track magnetic tape drive error messages
If magnetic tape drive errors are reported by the system
controller display, first clean the tape path thoroughly.
Note: The diagnostic codes that indicate a tape drive failure
begin with the number 21.
During cleaning, take time to inspect the tape path components
for defects, such as damaged tape cleaner blades, loose air
bearings, and cracked or misaligned reel flanges causing contact
with tape edges. Cleaning and inspecting components take only
minutes but go a long way toward maintaining the reliability of
the transport and minimizing downtime.
If cleaning does not resolve the problem, load another tape of
known good quality (to eliminate the possibility of the problem
being caused by a defective tape). If the problem persists and
there are no other operator-correctable actions indicated by the
status code on the operator control panel, perform Diagnostic
Test 01 and place a service call.
