132 Installation and Service Guide: Color Controller E-85A
Troubleshooting
Printing (continued)
Print quality is poor.
(Continued from previous
page.)
Out of calibration or calibration
information/curves on the active
partition are corrupted 1 Start Command WorkStation, click the
Calibrate
icon
in the toolbar. Click
Restore Device
in the Calibrator
window, and then click
OK
.
Restore Device restores the currently selected E-85A
calibration set to factory defaults.
If restoring default calibration does not solve the
problem, you may need to service the printer.
2 If restoring default calibration fixes the color quality,
the custom calibration may have been the cause of the
problem. Request that the site administrator recalibrate
the E-85A. For more information, 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 the system software.
4 If the problem persists, check for a faulty hard disk
drive.
Reboot the system. At the Serial ATA AHCI BIOS
screen on the monitor, wait for the Port-XX displays to
appear and press the
Pause/Break
key. If a hard disk
drive description appears next to the Port-01, Port-02,
and Port-03 entries, all three hard disk drives are good.
If “No device detected” appears next to:
•
Port-01, the 500GB hard disk drive in the top slot of
the chassis may be faulty.
•
Port-02, the middle 2TB hard disk drive may be
faulty.
•
Port-03, the bottom 2TB hard disk drive may be
faulty.
Replace the SATA data cable to the suspected faulty
drive. If the problem persists, replace the faulty drive.
Loose or faulty cable connections, or
problem with the printer interface
board 1 Recheck the printer interface cables and connections at
the back of the E-85A and the printer (see Figure 3 on
page 19).
2 Reboot the E-85A.
3 Restore the backup, or reinstall system software.
4 Replace the printer interface cables one by one.
5 Replace the printer interface board assembly.
6 Replace the motherboard.
