Hard Disk Drive Malfunction
When the control panel display and reports indicate “Hard Disk
Failure”, try the following recovery procedure before performing a
reformat procedure. The reformat procedure will delete all files.
1. Disconnect the power cord. Wait 10 seconds.
2. Disconnect the hard disk interface PWB from the mother PWB. Do
not remove any cables.
3. Connect the power cord.
4. Wait for the normal idle control panel display to appear (to
initialize the terminal without the hard disk).
5. Disconnect the power cord. Wait 10 seconds.
6. Connect the hard disk interface PWB tothe mother PWB.
7. Connect the power cord.
8. Wait for the normal idle control panel display to appear (to
initialize the terminal with the hard disk).
9. Enter the service mode.
10. Enter the soft switch mode (1+0+[Enter]).
a.
Select soft switch 029 and set to 01100011
b.

If the “Hard Disk Failure” was caused by a programing bug rather
than a valid disk failure, the queued transmit jobs should continue
normally. The documents stored to the disk may be printed using
the “pending jobs, view/delete” function. Print out a Pending Jobs
Report to obtain the numbers assigned to the stored documents.
The file numbers may be used to view (print) the stored documents
or delete them.
NOTE: If you try to print documents stored to the disk using the
“print from memory” function, the terminal will report that there
are no documents stored to the disk.
15. If the preceding procedure resolved the failure indication, return
the terminal to normal operation. If the failure indication remains,
go to step 16.
16. Perform the following:
a.
Disconnect the power cord.
b.
Remove the auxiliary tray rear cover.
c.
Remove the rear access cover.
d.
Disconnect P/J271 and P/J272 from the hard disk interface
PWB.
