VOLTAGE ADJUSTMENT SYSTEM, IMAGE FORMING APPARATUS, AND VOLTAGE ADJUSTMENT METHOD

摘要

PROBLEM TO BE SOLVED: To reduce a difference between DC voltages to be supplied to respective cores without increasing cost for a circuit board.SOLUTION: A detection part 21 detects first and second DC voltages V1 and V2. A voltage adjustment part 22 adjusts first and second setting values S1 and S2 so that the first and second DC voltages V1 and V2 detected by the detection part 21 fall within an allowable voltage range B1 with required voltages of a sub CPU 131 and a main CPU 132 as the center, and writes the first and second setting values S1 and S2 after the adjustment in memory 14 as first and second setting values S1 and S2 at the start-up of a circuit board 10.SELECTED DRAWING: Figure 4
