CHAPTER 2 the circuit applies a high voltage output bias. The high voltage output bias is applied only at the trailing edge of a single side print and during the second side of a duplex print. e. Toner sensing/cartridge sensing The EP-W cartridge has a toner sensor. The DC controller detects the toner level and whether a cartridge is installed when the developing AC bias is applied to the developing cylinder by the DEVELOPING AC BIAS DRIVE signal by checking the TONER LEVEL signal (TONRS) voltage. 2 - 20

e.
Toner sensing/cartridge sensing
The EP-W cartridge has a toner sensor.
The DC controller detects the toner level and whether a cartridge is installed when the
developing AC bias is applied to the developing cylinder by the DEVELOPING AC BIAS
DRIVE signal by checking the TONER LEVEL signal (TONRS) voltage.
