If the user can print the Configuration page from the printer touch panel but cannot print a job from a computer on the network, request
that the site administrator do the following:
• Check all printer components of the network, including cables, connectors, terminators, network adapter boards, and network
drivers.
• Activate the network and use it to communicate with other printers.
• Confirm that the applicable network settings in Setup (such as AppleTalk zone, IP address, subnet mask, and gateway address)
match the settings used in the network.
NOTE:
EPS file generation is not completely standardized among applications. Some users may encounter problems while printing
certain EPS files.

For information about printer files, see Printing, which is part of
the user documentation set.
Test the printer and service, if necessary (see the service doc-
umentation that accompanies the printer).
1. If you suspect that a custom calibration setting is causing
the problem, reset the calibration setting to its default
measurements:
In Command WorkStation > Device Center > General >
Tools, click Manage.
Calibrator opens.
In Calibrator, select the calibration setting that you suspect
is causing the problem, and then click View Measure-
ments.
Click Reset to Default Measurements, and then click Yes
to confirm.
If resetting to default calibration does not solve the prob-
lem, you may need to service the printer.
2. If restoring default measurements fixes the color quality,
the custom calibration may have been the cause of the
problem. Request that the site administrator recalibrate the
imagePASS. For details, see Color Printing, which is part
of the user documentation set.
3. If the problem persists after recalibration, the calibration
information on the hard disk drive may be corrupt. Reinstall
system software.
4. If the problem persists, the hard disk drive may be corrupt.
Verify that all hard disk drive cabling is correct.
5. If hard disk drive cabling is correct, you may need to re-
place the hard disk drive.
1. Check again the printer interface cable and connection at
the imagePASS and the printer.
2. Power off/on the printer.
3. Replace the printer interface cable.
Test the printer and service, if necessary (see the service doc-
umentation that accompanies the printer).
