Options service check
Service tip: When you have a problem with any of the options installed in the options slots on the
interconnect board, switch the non operating option to one of the other option slots to isolate the
failure.
Flash Memory Option(s)
Run a copy of the test page and check to see if the option you are checking is listed. The printer does
not recognize the option being installed if the option is not listed. Make sure the memory card is
installed correctly and is not broken or damaged. If the memory card is correctly installed and not
broken or damaged then run the
“Flash Test” on page 3-3 . If the test fails, replace the Flash card. If
the problem continues, replace the controller board.
DRAM Memory Option(s)
This service check is the same as the flash memory option service check with the following
exception:
Run the “SDRAM Memory Test” on page 3-9 from the menu if the SDRAM Memory card is
correctly installed and not broken or damaged. If the test fails, replace the SDRAM card. If the
problem continues, replace the controller board.
Hard Disk Option
Service tip: These printers support one hard disk option. Make sure only one hard disk option is
installed.
Make sure the fixed disk and the fixed disk board are correctly installed. Run the “Quick Disk Test”
on page 3-2 from the Device Test on the Diagnostics 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.
The “Disk Test/Clean” on page 3-2 is used to help restore the disk if the disk 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.
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.
Error Code 977 - Network Card x
A 977 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.
