REPLACEMENT
Service manual, section 3.7

Remind them to follow all notes and cautions in the manual.
Service manual, section 3.1.7
ˆ
First, make sure that the class is aware of the service notes for the development
and toner supply components.
Developer
ˆ
After installing the new developer, initialize the TD sensor (SP2801) after the
machine has warmed up. Note that you will need the developer lot number on the
bag.
ˆ
The door must also be open before you turn the power on: Follow the procedure in
the manual carefully. Use the procedure for B140/B246.
ˆ
There is no need to replace the developer in the class, because we did it at
installation. However, the class should be aware that the SP number is different
when adding new developer.
TD Sensor
ˆ
After installing a new sensor, initialize the TD sensor (SP 2801), and then initialize
the auto process control (SP 2962).
¾
Also, make sure that SP2208 is set for sensor control mode (that instruction
is not in the manual)
¾
2962: Process control initialization (only works if process control is enabled,
and the fusing unit temperature must be less than 100 C).
