The sensor section of the toner sensor detects the ratio of toner to carrier in the developer near it and converts it into a voltage.
Page 43 2AR-1 Toner density control Toner density control is conducted using the TARGET value as the reference which is the toner sensor initial output value set by maintenance item U130 when developer is loaded for the first time. Toner being replenished message Toner request message (forced toner feed) (Toner cartridge to be replaced.)
Page 44 E After replacing the toner cartridge, the toner feed motor (TFM) turns on to replenish toner. F When toner is replenished, the toner sensor output voltage falls until it drops to the toner feed stop level. The toner being replenished message disappears and replenishing stops.
Page 45 Correcting the toner sensor control voltage The toner sensor control voltage is corrected based on the absolute humidity and the total drive motor time so that the toner density is kept constant regardless of the changes in humidity and the total drive motor time. Toner sensor control voltage after correction = A + B + C A: Toner sensor control voltage before correction (value set by maintenance item 131) B: Correction data based on the absolute humidity...
Page 46 Computing the absolute humidity The external humidity sensor (EHUMSENS) and external temperature thermistor (ETTH) are located on the humidity sensor PCB (HUMPCB). The external humidity sensor (EHUMSENS) converts the relative humidity detected by the humidity sensing element into a voltage and sends it to the engine PCB (EPCB). The main PCB (MPCB)computes the absolute humidity based on this EHUMSENS signal and the temperature (ETTH signal) detected by the external temperature thermistor (ETTH).
Page 47 • Correction based on the total drive motor time The toner sensor control voltage is also corrected based on the total time the drive motor (DM) has been on from execution of maintenance item U130, so that the toner sensor output voltage is regulated properly. Correction data –...
