6.5.5 NEW FUSING UNIT DETECTION

[A]
There are two types of fusing unit: Service part, and maintenance kit part. Only the
fusing unit in the maintenance kit has this detection mechanism.
In the maintenance kit fusing unit, the looped wire on the fusing unit connector
contains a fuse [A]. When power is switched on after installing a new fusing unit,
the engine board detects the fusing unit through the looped wire as usual.
However, the fuse opens very shortly afterwards.
What happens next depends on the setting of Engine Service Mode - Meter
Service Charge:
- If Meter Charge Mode is enabled–
• After the technician replaces the fusing unit, the maintenance counter must
be reset with an SP mode (Engine Service Mode - PM Counter Reset).
- If Meter Charge Mode is disabled (default setting) -
• After the fusing unit has been replaced, the CPU detects the new unit and
automatically removes the "Replace Maintenance Kit" message. Then, the
maintenance counter resets automatically.
