4.4.8OBJECT POSITION command

The following table shows the normal sequence of the OBJECT POSITION command when used with this scanner.

Table 4-20

Step	Bus phase	Initiator operation	←→	Target operation

I	BUS FREE	Verifies bus free
2	ARBITRATION	Obtains bus-usage
		right
3	SELECTION	Selects target	→
				Drives BSY signal

4	MESSAGE OUT	Selects logical unit	→

5	COMMAND	Specifies OBJECT POSITION (CDB)	→	Loads/unloads paper (ADF)
6	STATUS		←	Reports GOOD status
7	MESSAGE IN		←	Reports message (Command Complete)
				Release BSY signal
8	BUS FREE
