Waste Oil Sensor
There is an enclosed area [A] on the rear left shoulder of the waste oil bottle. On
the inside wall of this area are two pinholes, through which the waste oil can flow
into the enclosed area. This enclosed area contains an actuator [B], which
interrupts the waste oil sensor [C] if no oil is in the area.
When the amount of waste oil becomes large enough for the waste oil to flow into
the area, the actuator floats on the oil. When the actuator leaves the waste oil
sensor, the message, “Waste Oil Bottle is Almost Full,” is displayed on the
operation panel.
NOTE: With this error message, another message, “Waste Oil Bottle Setting
Error,” can be displayed (
☛
Bottle Set Sensor).
After this message appears, the copier can operate until the number of rotations of
development drive motor K reaches the value specified with SP7-905-010. When
the number has reached this value,
an error message is displayed and the copier
stops its operation. When you dispose of the waste oil, the machine resumes its
normal operations (no need to switch the machine off/on).
6.12.6 NEW FUSING OIL SUPPLY UNIT DETECTION
The fusing oil supply unit [A] contains a fuse [B] in a circuit between the fusing unit
and the BCU board. The fuse opens shortly after a new unit has been installed in
the machine and the power is switched on. When the power is turned on or the left
cover is closed, the BCU checks whether a new fusing oil supply unit is installed by
checking the fuse condition. If the fusing oil supply unit has been replaced, the
machine detects the new unit and automatically resets the counter for the unit.
Oil near-end is detected by counting the number of prints made. The machine
indicates oil near-end 2,500 sheets before the life of the oil supply unit runs out.
This timing can be changed with SP7-905-14. . When the number has reached this
value,
an error message is displayed and the copier stops its operation.
