scan to mail is too blue

All, 

I have al brandnew Photosmart 7520 all in one and I like it a lot. But when i scan to mail, al my pdf's are with a blue tint.

Normaly the scanned paper must be white, but it is always blue. 

However when i make a copy on the machine or a print-job via pc the output is good.(not blue).

Any solution please?
