INTERFACE
Notes: 1. If the requested Transfer Length does not equal to
actually transferred data size, the scanner returns CHECK
CONDITION status and create Sense Data as bellow.
ILI = 1 :
INFORMATION : TL(requested Transfer Length) -
actual transferred data size
This status is sent to the latest READ command. For the
other READ commands, the GOOD status will be
returned. If requested Transfer Length in last READ
command equal to the data size that should be
transferred, CHECK CONDITION status will be
returned to next READ command.
2. In addition to Note 1, when completion of image data
transfer, the scanner sets EOM bit to 1. If initiator issues
REQUEST SENSE command for each READ command,
Sense Key will be set to NO SENSE but by checking
EOM bit completion of transfer can be detected.
EOM = 0 : Image data transfer is not completed.
EOM = 1 : Image data transfer has just completed.
Above specification is described in JBMS but it is not
recommended for speed performance reason.
3. After all image data of the window is transferred,
CHECK CONDITION status will be returned following
each READ commands. To scan another document, issue
SET WINDOW command and set window.
4. Enabling or disabling disconnection is depending on
IDENTIFY message related to READ command. If bit 6
of IDENTIFY message is 1, disconnection is enabled. If
bit 6 of IDENTIFY message is 0, disconnection is
disabled.
