6.8 Measurement at Replacement of High-Voltage Transformer
The high-voltage transformer does not need to be adjusted, however, when you check each value of
the main charger bias and the developer bias, it needs to be measured.
When carrying out the operation, be careful not to touch the electronic section because it is high
voltage.
