Hard Disk Option
Service Tip: The 5055-01x printers support one hard disk option. Be
sure only one 3.2 GB or larger hard disk option is installed. Be sure
the hard disk and the hard disk board are correctly installed. Run the
“Quick Disk Test” on page 3-23 from the Device Test on the
Diagnostic Menu when a problem is suspected either with the hard
disk system board or with the hard disk.
Note: The Quick Disk Test is a non-destructive test and indicates
Pass or Fail. If the test fails, replace the hard disk. If a problem still
exists, replace the hard disk board.
Use the “Disk Test/Clean” on page 3-24 to help restore the disk if
it contains bad data and is unusable. This test is divided into a
cleaning and a verifying or testing section.
Warning: This can be a very lengthy test depending on the disk
size. This test leaves the hard disk unformatted. The servicer or user
must reformat the disk using the Format Disk Menu operation. This
is a destructive type of test. All the data on the disk is destroyed and
should not be performed on a known good disk.
Network Card Option
The network is installed on the system board on network model
printers.
Error Code 976 - Network Card x (x=Network card 1, 2, or 3)
A 976 error code indicates an unrecoverable software error in
network card x. Verify that network card x is correctly installed in the
socket on the interconnect board and is properly grounded. If you
find no problem, contact your next level of support before replacing
the network card.
54 Network <x> Software Error
This error displays when the RIP software detects that a network
card is installed in slot x on the interconnect board but cannot
establish communications with the network card.
