Diagnostic Information

4039-1XX
63 Unformatted or Defective Disk The printer will ignore a disk it senses as
defective. Run the Quick Disk Test. If the
test fails, the disk is defective or the data
on track1 is bad. If the Quick Disk Test
passes but the disk does not work, run
the Disk Test/Clean (2 hr. test). Replace
the disk if instructed by the operator
panel.
7X Network Card Codes These user codes are documented in
various network card user manuals.
See
“Network Wrap Tests” on page 23.
80 Scheduled Maintenance Printer has reached 200,000 prints
(12C=100,000 prints) without
maintenance count reset.
88 Toner Low Toner sensor detects low toner.
90X Software Error Unrecoverable software error. If one of
these errors appeared during POST, or
while the printer was idle (not printing or
receiving data), or while trying to print
one of the internal test pages, replace
the system board. If the error appeared
while sending a job from the host to the
printer, turn the printer off, then turn it on
and try again. If the error appears again,
call the next level service support for
assistance.
917 Transfer Roll Error Cannot start servo operation. Verify
correct cable connections from the
Engine board to the HVPS. Make sure
there is continuity between the transfer
roller and its contact on the HVPS;
replace the transfer roll if the continuity
is correct. If there is no continuity, make
sure the HVPS contact returns to its
upward limit when depressed, and make
sure the left bearing of the transfer roll is
making proper contact.
