CHAPTER 5 TROUBLESHOOTING

2 Checking the ColorPASS as a Stand-alone Unit

To test the ColorPASS as a stand-alone unit:
• Disconnect the ColorPASS from the copier and from the network
• Check for possible startup problems
• Check Setup (See the Configuration Guide for details)

2.1 To Isolate the ColorPASS

1. Isolate the ColorPASS from the copier and from the network by disconnecting the fol-
lowing cables from their connectors on the back panel of the ColorPASS:
• Network connector
• Copier interface connector
2. Make sure the power cable to the ColorPASS is still in place.
3. Power on the ColorPASS and allow the startup diagnostics to run.

2.2 Errors and Beep Codes during Startup Diagnostics

When you turn on the ColorPASS or reboot, the system performs diagnostic tests that
check the motherboard. While the diagnostic tests are running, the name of each test is dis-
played on the Control Panel. If an error occurs during the startup diagnostics, the red activ-
ity light on the ColorPASS Control Panel turns on. At the end of the diagnostics, the red ac-
tivity light remains on and the error appears on the Control Panel.
Pressing and holding the fourth line selection button during the startup diagnostics dis-
plays the Service menu. This screen allows you to reinstall system software if required, re-
cover a backup of the system, and install options and system software upgrades.
If the system cannot display the startup diagnostic screen, the ColorPASS will indicate an
error with beep codes and a flashing or solid red activity light.
During startup, the diagnostics check the activity light to make sure it is
functional. The activity light on the ColorPASS Control Panel flashed red
Memo
briefly during this time even though no errors have occurred.
When you encounter any of these conditions, power off the ColorPASS and inspect the
inside of the tray for an obviously loose part or cable. Then check the other components as
suggested in the following tables. For all service, see "Accessing ColorPASS internal com-
ponents" on page 4-4. When you are finished, see "Restoring ColorPASS functionality after
service" on page 4-10.
T05-202-01 lists possible beep codes, the area on the motherboard reporting the error, and
how to correct the error. T05-202-02 lists the possible error messages that may be reported
to the Control Panel and the suggested corrective action.
