Mode No. Toner Density Setting --22 Function Data Selects the toner density setting. The toner 0: Standard density changes according to the copy length 1: Low after the developer is replaced. 2: High Copy length (A1 size) Std. Low High ~ 30 m (~50 sheets) 4.25V 4.35V 4.00V ~ 60 m (~100 sheets) 4.00V 4.30V 3.50V ~ 90 m (~150 sheets) 3.50V 4.25V 3.00V ~ 120 m (~200 sheets) 3.00V 3.75V 2.50V ~ 150 m (~250 sheets) 2.50V 3.25V 2.00V 23 Not Used to 24 Toner Density Sensor Voltage Setting --30 Toner Sensor --31 Voltage Display (Last Copy) Changes the toner density sensor voltage. 80: Standard Normally, the value is automatically adjusted 50 ← 80 → 120 when the new developer initialization (SP36) Low High is done. In this mode, PTL, main motor, QL and the bias voltage for non-image area can be turned on and off using the Copy Media key. Translucent paper = ON Translucent Film = OFF Displays the toner sensor output voltage for A = X,XX the last copy. (Beeper) A163 4-22 SM
