* Reader controller PCB (when making prints with the reader unit installed).
The video signals (DVDO0 through 7*) from the printer board1 are converted into
PWM video data signals (VDATA*; subjected to pulse width modulation on the DC con-
troller PCB); then, they are converted into two sets of low-voltage differential signals
(Note) with suppressed radiation noise, and are sent to the laser driver PCB.
