Starting The Diagnostic Software - Laptop Computer; Problem Solving - Communications Error - Xerox 8830 Service Manual

Starting the Diagnostic Software - Laptop
Computer
Do the following steps to start the diagnostic software when a laptop
computer is used to run the diagnostics for the Scanner.
See Figure 6-4.
1. Switch off the Scanner, the laptop computer, and the control
computer for the system to which the Scanner is connected.
2. Disconnect the Scanner SCSI Cable from the control computer.
3. Connect the Laptop Computer SCSI cable to the Scanner.
4. Ensure that all other SCSI connections are disconnected from the
Scanner.
5. Switch on the Scanner and wait 10 seconds.
6. Switch on the Laptop Computer and allow it to complete the boot
process.
l) Locate the SCSI7356 program and start it.
8. Enter the password ES8150 and press the <Enter> key on the
keyboard.
9. Press the Begin button on the screen.
10. Press the Normalize Cameras button.
• At this point you may normalize the Scanner's cameras, or you may
skip the test by pressing Exit, if you plan to perform any diagnostic
tests that require making an image, you should first perform a
camera normalization. Refer to Using the Diagnostic Software for
further information about features of the Diagnostic Software..

Problem Solving - Communications Error

If the Communications Error screen is displayed after starting the
SCSI7356 software:
• Switch off the Scanner and the controlling computer.
• Check that the SCSI cable is firmly connected to the Scanner and
the SCSI adapter port of the computer.
Diagnostics
• Switch on the Scanner; then switch on the computer.
• During the boot process, check that the following message is
displayed:
Host Adapter #0 - SCSI ID 0 - LUN 0: Xerox 7356 OOxx
If the message is not displayed, or "No SCSI devices found!" is
displayed, then there is a SCSI communications problem between the
Scanner and the computer that must be resolved before the software
can operate.
• If the computer has communicated successfully with other SCSI
devices, then the fault is probably in the Scanner or the SCSI cable.
Go to Section 2 of this Service Manual and isolate the fault.
• If the Scanner has communicated successfully with the customer's
host system during the service call, but not with the computer being
used to run the SCSI7356 software, then the fault is probably in the
SCSI cable or the computer. Check the cable, by substitution if
possible. If the fault still exists, then the fault must be corrected in
the computer or the SCSI adapter in the computer.
• if the customer's computer is running the SCSI7356 software,
isolate the fault by using the laptop computer instead.
• If the laptop computer is running the SCSI7356 software, isolate the
fault by using the customer's computer instead. The software may
be run from a floppy disk, avoiding the need to actually install the
software on the customer's computer.
• the SCSI cable may be too long
• The SCSI bus may not be terminated correctly. Go to SCSI
Connections and Scsi Termination for more information.
If the message is displayed, then:
• the SCSI cable may be too long
• The SCSI bus may not be terminated correctly. Go to SCSI
Connections and SCSI Termination for more information.
