Appendix A-54
If the ULX or ULY value is outside the maximum scan area of this scanner, this scanner
returns the following error information:
• Status: B’00001’ (CHECK CONDITION)
• Sense key: X’5’ (ILLEGAL REQUEST)
(e) 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 is outside the maximum scan area of this scanner, the following error information is
returned:
• Status: B’00001’ (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 or to less than two bytes for horizontal scanning.
Notes:
1. ULX, ULY, W, L versus maximum scan area:
0 < (ULX + W) ≤ 14592 (in 1/1200 inches)
0 < (ULY + L) ≤ 20736 (in 1/1200 inches)
2. Conditions for horizontal scanning:
9 ≤ [XR x W/1200] ≤ 7296 (dot)
≤ 9728 (dot) (with memory and IPC option)
(Values under 0 in [ ] are omitted.)
3. Conditions for vertical scanning:
1 ≤ [YR x L/1200] ≤ 10368 (line)
≤ 13824 (line) (with memory and IPC option)
(Values under 0 in [ ] are omitted.)
4. Conditions for horizontal and vertical scanning (in 1/1200 inches):
13200 (11”) < (ULX + W) ≤ 14592
When this condition is satisfied, following condition must also be satisfied.
0 < (ULY + L) ≤ 19842 (A3 length)
Notes:
This is not the guaranteed specification but the scanner may read the long document
which fits the following.
i) 0 < ULY + L ≤ 33072 (@1/1200 in.)
ii) L ÷ 1200 × YR ≤ 16383 line
