UX-A260U 3. Operational description CHAPTER 5. CIRCUIT DESCRIPTION Operational descriptions are given below: • [1] Circuit description When a document is loaded in stand-by mode, the state of the document sensor is sensed via the 1 chip fax engine (SCE214V). With depression of the START key in the off-hook state, transmission takes place. Then, the procedure is sent out from the modem and the motor is rotated to move the document down to the scan line.
