Toshiba e-Studio 351c

When the developer material is replaced, adjust the auto-toner sensor in the following procedure.

1. Install the cleaner and developer unit.
   Note:
   Do not install the toner cartridge.
2. While pressing [0] and [5] simultaneously, turn the power ON. The following message will be displayed.
3. 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
4. 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.
5. 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
6. 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

   Note:
   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

   Note:
   Since the adjustments for “Y”, “M” and “C” are controlled by the light sensor, the humidity correction is not performed.
7. Turn the power OFF.
8. Install the toner cartridges
