(c)Window identifier: Byte 0
Specifies a unique value that identifies a window. The value may be 0 to 255. If two or more window identifiers are specified for a single set of window data, the most recently specified identifier is validated This scanner allows only one window to be set Therefore, only 0 may be specified in this field. II other than 0 is specified, this scanner returns the following error:
∙Status: B~0000l' (CHECK CONDITION)
∙Sense key: X'5' (ILLEGAL REQUEST)
(d)Auto: Byte 1
This scanner does not support auto. If a value other than 0 is specified, this scanner returns the foIl error:
∙Status: B'0000l' (CHECK CONDITION)
∙Sense key: X'5' (ILLEGAL REQUEST)
(e)X, Y resolution (XR, YR): Bytes 2 to 3 and 4 to 5
Specified here are the resolutions in the horizontal (X) and vertical (Y) scanning directions, in pixels per
inch. If 0 is specified, the default value (300 dpi) is assumed. The acceptable resolution value is as 60, 75, 80, 100, 120, 150, 200, 240, 300, 600. If a value is specified that does not comply with these conditions, this scanner returns the following error:
∙Status: B'0000l' (CHECK CONDITION)
∙Sense key: X'5' (ILLEGAL REQUEST)
(f)Upper left X,Y(ULX, ULY): Bytes 6 to 9, A to D
Specified here are the X and Y coordinates of the
∙Status: B'00001'(CHECK CONDITION)
∙Sense key: X'5' (ILLEGAL REQUEST)
(g)Width, length (W, L): Bytes E to 11, 12 to 15
Specifies here are the width and length of the window, in units of 1/1200 inches. If the W or L value outside the maximum scan area of this scanner; the following error is returned:
∙Status: B'0000l' (CHECK CONDITION)
∙Sense key: X'5' (ILLEGAL REQUEST)
The same error is also returned if this scanner is set to less than one raster line for vertical scanning less than two bytes for horizontal scanning.
Notes:
1.ULX, ULY, W, L versus maximum scan area: 0< (ULX + W) ó 10200 (in 1/1200 inches)
0< (ULY + L) ó 13937 (in 1/1200 inches) for flatbed scan 0< (ULY + L) ó- 16800 (in 1/1200 inches) for ADF scan
2.Conditions for horizontal scanning: 9< {XR x W/1200] ó 5100
