I have Canon 9000f MK2 with latest drivers installed.

When scanning A4 documents, using proper settings, parts outside of A4 area are scanned so that resulting image contains A4 document plus some to the right and below it.

The image of a scanned A4 document ends up being of correct size in pixels for a given scanning resolution.

Here are the images of A4 paper scanned at 150 dpi with scanner lid down and up to accent the added areas:





And these show that A4 paper is properly aligned:

I tried scanning using VueScan but end up getting the same results.

What could be wrong?

Thanks.
 
Solution
Check the settings for document de-skew. De-skew requires a bit of overscan and results in this, if the paper positzon is not recognized. Cleaning the inside of the lid sometimes helps.
