2.7.10.7 Fuser Fan Control

The Fuser Fan is controlled (ON/OFF or High/Low rotations) by the
operation modes as follows:
Table 2-19. Fuser Fan Control
Warm-up Fuser Fan: OFF
Ready Fuser Fan: ON (Rotation: Low)
Printing Fuser Fan: ON (Rotation: High)
Light Sleep Fuser Fan: OFF
NOTE: The Fuser Fan control differs in the Error mode and Diagnostic
Test mode according to the errors and diagnostics. For
example, if a paper jam error has occurred, the Fuser Fan is
turned ON and the rotation is set to Low.
NOTE: If the mode transition (to the Deep Sleep or Light Sleep modes)
has been set and the time for the transition is shorter than
normal, the Fuser Fan remains ON for the predetermined period
to prevent the printer from overheating.

2.7.10.8 Detection Controls in Fuser

1. Oil Roll Assembly end of life detection
The life of the Oil Roll Assembly is determined by the number of
printings (oil quantity being used). Two counters (PV and Oil Rate)
are used to detect the life of the Oil Roll Assembly. If either counter
reaches a predetermined value, an end of life warning or No Fuser
Oil (life expectancy exceeded) error is detected.
(a) PV Counter
The PV Counter counts the number of printings. The counter
detects the following.
Table 2-20. PV Counter
Oil Roll Assembly end of life warning
("Oil Roll Near Empty")
No Fuser Oil ("Replace Oil Roll")
NOTE:
The count described above is based on the following:
1 count:
- Printing a sheet that has a paper length (feed direction) of
219mm (LETTER/LEF) or smaller
2 counts:
- Printing a sheet that is larger than the above.
