Sharp MXC301

This adjustment is needed in the following situations:

• When the high voltage power PWB is replaced.
• U2 trouble has occurred.

1. Enter the SIM 8-2 mode.
2. Enter the adjustment value (specified value) in the middle speed mode, and press [OK] key.
3. 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 high voltage power PWB.

NOTE:

Note that the adjustment value may differ depending on the high voltage power PWB.
Since the adjustment value label is attached on the 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.

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.
