Page 328: Id Sensor
DEVELOPMENT 28 April 2005 6.6.6 ID SENSOR The ID sensor [A] checks the density of a temporary image (known as the ID sensor pattern), projected onto the drum with the LED print head. The density is used to determine whether more toner is needed.
Page 329: Toner End/Near-End Control
28 April 2005 DEVELOPMENT 6.6.7 TONER END/NEAR-END CONTROL Near-end Detection Near-end occurs if the ID sensor reads Vsp/Vsg values three times in succession that are larger than the Vend value specified with SP2927 001 (Toner Near End Level),. End Detection/Recovery from Near-end After the machine enters the near-end status, the ID sensor pattern check accelerates from 100 cm to 20 cm intervals.

DEVELOPMENT 28 April 2005 6.6.8 TONER END RECOVERY The flowchart below illustrates the toner end recovery cycle. Toner end recovery entails opening the toner hopper cover when the near toner or toner end messages are displayed, then closing the cover after replacing the toner cartridge.
Page 331: Toner Density Control
28 April 2005 DEVELOPMENT 6.6.9 TONER DENSITY CONTROL Overview The machine controls toner density by switching the toner supply clutch on/off, with on/off timing determined by the ID sensor readings from the sensor pattern on the drum. Toner Supply Modes This machine has three toner supply modes.
