Note

READ command

If the document is shorter than the window area specified by the SET WINDOW command, the deficient portion is supplemented by white data. The deficient portion is supplemented so that the data covers the entire specified window area and is transferred.

4.4.9READ command

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

Table 4-21

Step	Bus phase	Initiator operation	←→	Target operation

1	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 READ (CDB)	→	Reads document
6	DATA IN		←	Transfer image data
7	STATUS		←	Reports GOOD status
8	MESSAGE IN		←	Reports message (Command Complete)
				Releases BSY signal
9	BUS FREE
