Problem with the printer
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.
■ Checking the network
Printing problems may arise if the network hardware or software is not set up properly or does not match network settings on the
imagePRESS Server. Problems may also arise when printing from a specific application or printing a particular file.
Most of these problems show up as printing problems and do not necessarily indicate a imagePRESS Server malfunction. The
customer's site administrator can eliminate many printing problems without requiring you to make a service call. The site
administrator deals with:
• Error conditions on the printer
• Network connection problems that result in the printer not appearing in the list of printers on the customer's computers
NOTE:
If the printer does not appear in the list of printers on the network, there may be another device on the network with the same
IP address.
• Conflicting network settings in Setup and on the customer's computers
• Printing problems caused by inappropriate Setup options
• Application-specific printing errors caused by missing or incorrectly installed printer description files
Possible cause Suggested action
1. If you suspect that a custom calibration setting is causing the
problem, reset the calibration setting to its default measure-
ments:
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 Measurements.
Click Reset to Default Measurements, and then click Yes to
confirm.
If resetting to default calibration does not solve the problem,
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 imagePRESS
Server. For details, see Color Printing, which is part of the
user documentation set.
3. If the problem persists after recalibration, the calibration infor-
mation 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 replace
the hard disk drive.
1. Check again the printer interface cable and connection at the
imagePRESS Server 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 docu-
mentation that accompanies the printer).
