2.8.6 NEW FUSING UNIT DETECTION
When the PM (fusing) counter reaches 120K, "Replace Maintenance Kit" is
displayed.
The machine detects when the new maintenance fusing unit is installed by
checking the circuit through the detector hook [A]. The detector hook is hooked on
the edge of the fusing pressure roller shaft [B]. As the pressure roller rotates, the
detector hook is released from the press roller shaft and the circuit becomes
opened. Once the detector hook is released, it will not re-engage with the shaft for
the duration of the fusing unit’s life. Then, the machine clears the PM (fusing)
counter.
Please note that this detection is done only with the maintenance fusing unit, and
the detector hook is not installed in the fusing unit which is initially installed in the
machine.
NOTE: If the PM is done by replacing individual parts (not by replacing the
maintenance fusing unit), make sure to reset the PM (fusing) counter using
the SP mode (Service Menu 2: FuserCount clr). Otherwise the “Replace
Maintenance Kit” message on the LCD will not be cleared.
