Minilab service 153 Report post Posted May 25 Yes, on Fuji 500 used built in densitometer - part number 620Y100002A . 620Y100002A has three connectors and they all are connected into two connectors on LDD27 ( laser control board, connectors LDD31 and LDD32 ) . All control signals there ( head control, signals to control motor, thermosensor and many other ) . 620Y100002A is absolutely different than AD300, which is used on 570. AD300 is independent unit, which has all control circuit inside it. It has only one small connector where is power supply ( 24V ) , ground and RS interface - Rx ( receiver ) and Tx ( transmitter ) .
