Adjustment. Auto-Toner Sensor
When the developer material is replaced, adjust the auto-toner sensor in the following procedure.
- Install the cleaner and developer unit.
Note:
Do not install the toner cartridge. - While pressing [0] and [5] simultaneously, turn the power ON. The following message will be displayed.
- Key in a code and press the [START] button.
200: All developer materials
201: Developer material Y
202: Developer material M
203: Developer material C
204: Developer material K
206: Developer material Y, M, C - Adjustment for "K" (Magnetometric sensor control)
• The following message will be displayed approx. 2 minutes later.
Note:
The current sensor voltage (V) shown in (B) automatically changes, gradually approaching the target value for adjustment reference voltage shown in (A).
• In 30 to 60 seconds, the current sensor voltage (V) in (B) is converged. Then the sensor output control value (bit value) corresponding to the initial developer material is displayed in (C).
Note:
Be careful that the values in (A), (B) and (C) vary with humidity.
• In case of single-color adjustment, press the [ENTER] button to store the adjustment results in memory when the control value is displayed. In case of multiple-color adjustment, it is automatically proceeded to the adjustment of next color. - Adjustments for “Y”, “M” and “C” (light sensor control)
• In 15 to 45 seconds, the following message will be displayed (The time varies with the number of colors to be adjusted).
Note:
The current sensor voltage (V) shown in (B) automatically changes, gradually approaching the target value for adjustment reference voltage shown in (A).
• After approx. 5 seconds have passed, the current sensor voltage (V) in (B) is converged. Then the sensor output control value (bit value) corresponding to the initial developer material is displayed in (C).
• In case of single-color adjustment, press the [ENTER] button to store the adjustment results in memory when the control value is displayed. In case of multiple-color adjustment, it is automatically proceeded to the adjustment of next color. When the adjustments of all colors have finished and [ENTER] is lit, press [ENTER] button to store the adjustment results in memory - Standard of adjustment value range (A):
Adjustment reference voltages (V)Humidity(%) K Y M C 29.9 or below 2.47 1.25 1.25 1.25 30.0-44.9 2.49 45.0-59.9 2.50 60.0-74.9 2.69 75.0 or above 2.86
Since the adjustments for “Y”, “M” and “C” are controlled by the light sensor, the humidity correction is not performed.
(B): Current sensor voltages (V)Humidity(%) K Y M C 29.9 or below 2.37-2.57 1.15-1.35 1.15-1.35 1.15-1.35 30.0-44.9 2.39-2.59 45.0-59.9 2.40-2.60 60.0-74.9 2.59-2.79 75.0 or above 2.76-2.96
Since the adjustments for “Y”, “M” and “C” are controlled by the light sensor, the humidity correction is not performed. - Turn the power OFF.
- Install the toner cartridges
