Hexadecimal:  10 04 03

Parameters:  None

Return:  1 byte to be interpreted as follows:  

0

Fixed to 0

1

Fixed to 1

2

1 = jam in path

3

1 = knife error

4

Fixed to 1

5

1 = unrecoverable error

6

1 = a/d out of range error

7

Fixed to 0

Description: This immediately returns one byte of imager status.

Hexadecimal:  10 05 06

Parameters:  None

Return:  None

Description: Use this command if a catastrophic error has occurred and prevents the image processor from 
completing a formatting and transmission operation. Issuing this command cancels any buffered or in-process image 
transmission command.

Parameters: m = 0 specifies scan only, m = 1 specifies scan and transmit using the configured image format properties 
and TIFF tags at the time of the scan ending.  When m=0 the application is responsible to send the 1D B6 command 
to attach all tags before performing the next scan or transmitting the image.  For m=1 the 1D B6 command is handled 
internally. p = 1 wait for a document at the back sip entry, p = 2 wait for a document at the top front entry, p = 3 wait 
for a document at either entry point. A special top entry option p = 6 is used to scan Cards and Other thick media. r 
specifies document sides to transmit, 0= both,  1= bottom, 2= top.

Return:  After a scan this command returns to the command port and if applicable to the configured imager port an 
imager status, followed by a 4 byte file length nL nML nMH, nH (little endian sequence = low to high byte), indicating 
the size of the optional TIFF that follows: 0 = no image appended.

Note that FileIndex p is the value that will be used for the next bottom scanner image, so it should be decremented by 
2 if the scan status S< 7 to retrieve document images that were captured.

1D 49 B8 s m n pL pH rL rH reports the scanner state after scanning if the image is not attached.
