The data displayed by the lower two digits are A/D input values of the original sensor, and is expressed in decimal.
11 | Initial grid bias setting |
Used to set the initial grid bias in the normal mode, the photo mode, the toner save mode, and the patch measurement mode.
When this simulation is executed,
Since there are two or more display items, the third digit is used to make distinction between the light reception level and the original judgment level, and the lower two digits are used to display the data.
The display is selected by the magnification ratio key.

A | 1 ∼ 99 | Initial grid bias data (normal mode) |
|
| Set the grid voltage to 750V. |
|
| When the grid voltage is decreased by 1, the voltage is decreased by |
|
| 5V. When the grid voltage is increased by 1, the voltage is increased |
|
| by 5V. |

b |
| Initial grid bias data (Photo mode) |
|
| Set the grid voltage to 750V. |
|
| When the grid voltage is decreased by 1, the voltage is decreased by |
|
| 5V. When the grid voltage is increased by 1, the voltage is increased |
|
| by 5V. |

Enter the set value and press the PRINT button to store the value and start copying. After completion of setting, press the CA key to cancel the adjustment mode.
12 | Copying without grid bias correction |
Used to make copying without grid bias correction and drum mark check.
When this simulation is executed,
During
After completion of
After starting copying, the grid bias correction is not performed.
The number of multi copy cannot be set. (Single copy only)
After checking the operation, press the CA key to cancel the mode.
(Note) This simulation is used to judge whether the F2 trouble is caused by the grid bias correction or by the process or the high voltage section trouble.
