BTR:
The BTR (Bias Transfer Roll) is in contact with
the Drum and rotates along with the Drum being
driven by the Drum Gear. The BTR applies a
positive charge to the back side of the paper
when the paper travels between the BTR and
the Drum. The toner image transfers from the
Drum surface to the front side of the paper being
attracted by the positive charge on the back side
of the paper.
Sensor Toner:
A magnetic sensor that detects when toner is
low in the Toner Compartment of the Imaging
Cartridge. (Amount of toner is monitored by both
Sensor Toner and a software counter, and
“Toner Low” message is displayed whenever
the condition is detected by Sensor Toner, prior
to the status of software counter.)
Switch Assembly 5V Interlock:
Detects the closing of the Cover Assembly Exit
as illustrated in figure below. The signal is used
in the control circuit for the Printer.
