58 (or 57.2) SERVICE (Fan Failure)
The 58 SERVICE indicates that the DC Controller detected a
failure in the Exhaust Fan (FM1) in the printer or the optional
duplexer. When troubleshooting this problem, perform the
following steps in the order given.
1 Check that the fan is mounted correctly in its shroud.
2 Check that the fan blades are not blocked.
3 Check that the Cooling Fan connector is firmly seated on the
DC Controller (see Figure 7-16 or Figure 7-17 for location).
If the above checks are satisfactory, replace the fan.
Note
Verify the direction of air flow. Air should blow
out of the printer.
