Paper height HP OfficeJet 150

[Benji]

The height of the paper size is limited to letter size:

> scanimage -- help -d hpaio:/usb/Officejet_150_Mobile_L511?serial=MY2A9720DR
...
-y 0..277.707mm [277.707]
        Height of scan-area.
...

When I try to scan a A4 document, the bottom of the page is "cut off". But as there is the limit, it is also not possible to set A4 as size:

> scanimage -x 210 -y 296 -d hpaio:/usb/Officejet_150_Mobile_L511?serial=MY2A9720DR
scanimage: setting of option --br-y failed (Invalid argument)

I would like to look for some more details, where the limitation comes from. Especially, as the OfficeJet 150 has and ADF, which should not have any trouble scanning pages longer than letter size.

Where is the paper size limitation set?
Where are the properties for the device (hpaio:/usb/Officejet_150_Mobile_L511?serial=MY2A9720DR) stored?

Thanks
Ben

Is there a way, I can get some feedback on this? :-)

An Ubuntu task has been created but I see no information relating to the version of Ubuntu being used. Was this task created in error? Please advise.

NO response to my comment #4.
If this issue affects an Ubuntu release then we need to know which one(s)
Changing status to "Invalid" and closing for now.
