Configure Scan Options

Hexadecimal: 1D C6 m n
Parameters:
m n Description
0 - Configure Imager default settings. Parameter n is ignored.
1 0 Disable auto eject on top scan jam (default).
1 1 Enable auto eject on top scan jam.
2 n Set maximum tag storage memory to n Kbytes. Default 4K. Range 2K to 64K. Out of range
parameter defaults to 4K.
Return: None
Description: Configures scan options. Parameter m>2 reserved for future options This setting is retained across
power cycles.
Configure Max Scan Width & Height
Hexadecimal: 1D C7 wL wH lenL lenH
Parameters: wL wH is the maximum width of a scan in pixels (<= physical maximum 832); lenL lenH is the maximum
length in pixels (<= 2284 ~ 11.25"). The width should be values evenly divisible by 4 value will be truncated by zeroing
out the lowest-most 2 bits.
Return: None
Description: This sets the maximum values for all scanned documents to within ½ mm (4 pixels). As the imager must
be prepared for a maximum size, this allows the firmware to use optimum buffers and thus provide for retaining more
image slots in a circular buffer arrangement.
This setting is retained across power cycles.

Transmit Printer Type (Extended Existing Command)

Hexadecimal: 1D 49 02
Parameters: None
Return: M a single byte, as specified in existing commands, with its undefined bit #5 now used to indicate imager
installed. 0= not present (existing definition), 1= imager present (new)
Description: This is an additional definition that uses a previously undefined bit to tell applications whether or not an
imager is present.
