3. Not Ready state: Canceling
When the system is determining whether to cancel a Not Ready
state, it cancels the state after running the P/H Motor Assembly for a
predetermined period. The following describes how a Not Ready
state is canceled:
(a) The system has already accepted a print signal in the B/W mode
after printing the last page in the YMCBk mode.
When the Fuser Exit Sensor detects the last sheet (YMCBk
mode), the system turns on the Heater and inhibits printing for a
period requiring 2 circumferences (nominal) of the belt. The
system then cancels the Not Ready state.
(b) The system has not accepted any B/W mode printing signal
after printing the last page in the YMCBk mode.
If a B/W mode print signal comes within 1 minute after the
YMCBk mode printing has completed, the system turns on the
Heater and inhibits printing for a period requiring 2
circumferences (nominal) of the belt. The system then cancels
the Not Ready state. (If a Cycle Down Sequence is executed
after YMCBk mode printing, the Not Ready state is not
canceled.)
Chapter 2 Operating Principles

2.7.10.6 Oil Roll Control

If the Oil Roll in the Oil Roll Assembly continuously touches the Heat
Roll, the Fuser Oil may degrade and oil stains may appear on the paper.
The Oil Roll needs to touch (advance to) the Heat Roll only during the
fusing operation; at all other times, the Oil Roll must be separated
(retracted) from the Heat Roll. The Oil Cam Solenoid controls the
advancement/retraction of the Oil Roll Assembly.
NOTE: To advance the Oil Roll, the system continuously turns ON the
Oil Cam Solenoid. To retract the Oil Roll, the system
continuously turns OFF the Oil Cam Solenoid.
(The mode is changed by the rotation of the P/H Motor
Assembly.)
NOTE: After receiving the Oil Cam Solenoid ON/OFF signal, the time
required for Oil Roll advancing and retracting is 1.1 seconds in
standard speed mode and 2.2 seconds in half-speed mode.
