Troubleshooting the optional hard disk
Item Explanation
The printer does not
recognize the optional
hard disk.
Turn the printer power off and verify that the hard disk is inserted correctly and is
securely fastened. Print a configuration page to confirm that the optional hard
disk has been recognized. (See “Configuration page” on page 83.)
You receive this
message:
DISK FAILURE.
EIO X DISK
NOT FUNCTIONAL
Turn the printer power off and make sure that the EIO disk is inserted correctly
and securely fastened. If the printer control panel message continues to appear,
the optional hard disk needs to be replaced.
You receive this
message:
Disk is Write
Protected.
Fonts and forms cannot be stored on the optional hard disk when it is write
protected. Use the Device Storage Manager in HP Web Jetadmin or the
Macintosh-based HP LaserJet Utility to remove the write protection from the
optional hard disk.
Press S
ELECT ( ) to open the printer control panel menus.
You attempted to use a
disk-resident font, but the
printer substituted a
different font.
If you are using PCL, print the PCL Font Page, and verify that the font is on the
optional hard disk. If you are using PS, print the PS Font Page and make sure
that the font is on the optional hard disk. If the font is not on the optional hard
disk, use Device Storage Manager in HP Web Jetadmin or the Macintosh-based
HP LaserJet Utility to download the font. (See “PS or PCL font list” on page 86.)
