I have an interesting issue by one of my clients.

When scanning with WIA using the ADF, I get only a small part of each page as the image, about 2 by 4 inches. Instead of 8.5 by 11.

The same code on my pc/scanner works just fine. Also by this client it works fine on the flatbed. The issue crops (pun intended) up only with the ADF.

I haven't the foggiest idea where to start looking.

I'm posting here an iteration of the WIA Item properties i can get in code:.

0:Access Rights=3

1:Bits Per Channel=1

2:Bits Per Pixel=1

3:Brightness=0

4:Buffer Size=65535

5:Bytes Per Line=108

6:Channels Per Pixel=1

7:Color Profile Name=sRGB Color Space Profile.icm

8:Compression=0

9:Contrast=0

10:Current Intent=0

11:Data Type=0

12:Filename extension=BMP

13:Format={B96B3CAB-0728-11D3-9D7B-0000F81EF32E}

14:Full Item Name=0001\Root\Scan

15:Horizontal Extent=850

16:Horizontal Resolution=300

17:Horizontal Start Position=0

18:Item Flags=532483

19:Item Name=Scan

20:Item Size=0

21:Media Type=2

22:Number of Lines=1400

23:Orientation=0

24:Photometric Interpretation=0

25:Pixels Per Line=850

26:Planar=0

27:Preferred Format={B96B3CAB-0728-11D3-9D7B-0000F81EF32E}

28:Rotation=0

29:Threshold=128

30:Vertical Extent=1400

31:Vertical Resolution=300

32:Vertical Start Position=0

And these are the properties for the WIA Device:

0:BaudRate=

1:Description=Canon D1300/MF6700

2:DeviceKey=D1300

3:Document Handling Capabilities=39

4:Document Handling Select=1

5:Document Handling Status=34

6:Driver Version=3.0.0.0

7:Firmware Version=1.00

8:Full Item Name=0001\Root

10:Horizontal Bed Size=8500

11:Horizontal Optical Resolution=300

12:Horizontal Sheet Feed Size=8500

13:Item Category={F193526F-59B8-4A26-9888-E16E4F97CE10}

14:Item Flags=76

15:Item Name=Root

16:Manufacturer=Canon

17:Max Scan Time=3600000

18:Minimum Horizontal Sheet Feed Size=10

19:Minimum Vertical Sheet Feed Size=10

20:Name=Canon D1300/MF6700 (Network: 180CACDB1143)

21:Page Height=14000

22:Page Size=2

23:Page Width=8500

24:Pages=1

25:PnP ID String=\?\root#canon_mf_network#0000#{6bdd1fc6-810f-11d0-bec7-08002be2092f}

26:Port=CNMFNPSCAN_180CACDB1143

27:Preview=0

28:Remote Device ID=

29:Server=local

30:Sheet Feeder Registration=1

31:Show preview control=1

32:STI Driver Version=3

33:STI Generic Capabilities=17

34:Type=65537

35:UI Class ID={E2DCAEBD-D51C-413d-86A5-685670AA9C04}

36:Unique Device ID={6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0001

37:User Name=ABC-PC\ABC

38:Vertical Bed Size=14000

39:Vertical Optical Resolution=300

40:Vertical Sheet Feed Size=14000

41:WIA Version=2.0

If it helps any, then the possible list of DPI resolution does not seem to work correctly either. I get the subtype as a RangeSubType with the following properties

Min:50,Max:600,Step:1

Which I believe is incorrect...

Hi, did you solve it somehow?Lukas Caniga
yes. though probably via twain. im not sure. also most of my apps today are web based so its less relevant.Yisroel M. Olewski
I had exactly this issue just with Cannon printers. HP was ok. It was solved by setting up 6151 and 6152 properties.Lukas Caniga
