Back-up of service mode
In factory setting, adjustments are made for each machine, and adjustment values are written in the service label.
When you replaced the CCD unit (CCD PCB) or the DC controller PCB, or executed the RAM clear function, adjustment values for ADJUST or OPTION return to default. Therefore, when you made adjustments and changed values of the Service Mode in the field, be sure to write down the changed values in the service label. When there is no relevant field in the service label, write down the values in a blank field.
