Sharp MXC310
Adjustment. 1-A Adjust the main charger grid voltage
This adjustment is needed in the following situations:
- When the MC high voltage power PWB is replaced.
- U2 trouble has occurred.
- The PCU PWB has been replaced.
- The EEPROM of the PCU PWB has been replaced.
- Enter the SIM 8-2 mode.
- Select an output mode and an item to be adjusted.
- Enter the adjustment value (specified value) in the middle speed mode, and press [OK] key. (For the 4.3 Inch LCD model, press the OSA shortcut key.)
When [EXECUTE] key is pressed, the voltage entered in the procedure 3 is outputted for 30sec and the set value is saved. When [EXECUTE] key is pressed, the output is stopped.
Enter the adjustment value of each mode which is specified on the label attached on the MC high voltage power PWB.
NOTE:
Note that the adjustment value may differ depending on the MC high voltage power PWB. Since the adjustment value label is attached on the MC high voltage PWB, the PWB must be removed in order to check the adjustment value. This is a troublesome procedure. Therefore, it is advisable to put down the adjustment value in advance.

| D | MIDDLE SPEED GB_Y | Y charging/grid bias set value at middle speed | 150 - 850 | |
| LOW | A | LOW SPEED GB_K | K charging/grid bias set value at low speed | 150 - 850 |
| B | LOW SPEED GB_C | C charging/grid bias set value at low speed | 150 - 850 | |
| C | LOW SPEED GB_M | M charging/grid bias set value at low speed | 150 - 850 | |
| D | LOW SPEED GB_Y | Y charging/grid bias set value at low speed | 150 - 850 | |

When the adjustment value (specified value) of the middle speed mode is set, the adjustment values of the other modes are automatically set according to the middle speed mode setting in a certain relationship.
NOTE:
Since the high voltage output cannot be checked with a digital multi meter in this model, a judgment of the output must be made by checking the print image quality.
