Installation and Service Guide: Color Controller E-85
Suggested action
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-85
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-85. 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.
1 Recheck the printer interface cables and connections at
the back of the E-85 and the printer (see
page 19).
2 Reboot the E-85.
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.
