C. TCR window bias
• Since the optical TCR Sensor is used for C, M, and Y, a bias is applied to the TCR win-
dow to prevent toner from sticking to it. No bias is applied to the TCR Sensor for K, which
is the magnetic type.
• The bias is applied from the bias terminal of the LED Unit by way of the mounting screw
of the TCR window to the TCR window.
