SERVICE TOOLS Mode No. New Developer Initialization 36 Darker Image Density *37 Function Carries out the new developer initialization for 5 minutes. The machine counts down the remaining time on the display. After the initialization, the machine automatically adjusts the toner sensor output to 4.0 ± 0.1 V. During the toner sensor adjustment, "Adj" is displayed. When the adjustment is completed, the machine automatically returns to normal operating mode. Sets the range of the ID density control to give finer control over darker images. Default level 3 shifts to new ID level 7 (see the chart for the new levels). ID level 8 to 14 cannot be shifted. Data If the initialization is canceled before returning to the normal operating mode, do it again from the beginning. If the machine fails to adjust the toner sensor output, "E = 11" is displayed. 0: Standard Density 1: Darker Image Density The light sensor output and development bias will change as follows: ID level 7 6 5 4 3 2 1 Default ID level 3 2.5 2 1.5 1 - - Light Sensor Output 0.9 0.9 0.88 0.84 0.8 0.8 0.8 Development Bias 160 140 120 120 120 80 60 Release Fusing Recovers from the fusing unit SC 0: Release SC 38 Unit Service Call condition.
