Canon DR-M140 pages get cut off when using SDK

[cityvoice]

I'm having a problem with my canon scanners in using SDK. When I scan an A4 paper it cuts of the first ( or last ) 1cm of the page.
the same problem like:
https://gitlab.com/sane-project/backends/-/issues/476#note_1735474004

I'm using SDK to develop an electron app, I using browser to send a scan job to scanner with options:
{
InputSource: 'ADF',
Duplex: true,
Resolution: 300,
ScanRegion: 'A4',
}

it cut off the bottom 1cm of the page. But it works fine when using NAPS2 gui or command line tool NAPS2.Console.exe

so how to resolve this bug, thanks!

Try "ScanRegions" instead of "ScanRegion".

ScanRegions

hi@cyanfish, very thanks for your replyment, I have tried "ScanRegions" instead of "ScanRegion", but the scan server throws 400 error.

the post data is :

so how should i do? thanks

[cyanfish]

Looks like a bug in the ESCL client library as it's generating invalid XML, I'm assuming you're using the code from the naps2-webscan sample? If so you can try commenting out lines 25 and 33 here (the lines with "MustHonor").

@cyanfish, thanks again, you are right,xml is invalid, change region to regions works.
