An image formation device using an I2C bus and a control method therefor.
The image formation device includes a plurality of detection sensors for detecting
operation states of the peripheral devices; a plurality of A/D conversion units
for converting into digital signals detection result signals output from the plurality
of detection sensors; a plurality of slave devices for separating and storing by
detection sensor the detection result signals converted into the digital signals
by the A/D conversion units, and sending the stored detection result signals according
to a signal requesting detection results; and a master device for requesting to
the slave devices the detection result signal from at least one detection sensor
out of the plurality of detection sensors in order to verify the operation states
of the peripheral devices, such that the slave devices and the master device send
and receive data to and from each other through a serial bus.
