WorkCentre 6027 cannot scan multiple pages on platen to PDF

I have just upgraded from WorkCentre 6015 to WorkCentre 6027.

I am trying to scan multiple page expense reports using the platen. I cannot use the document feeder (ADF? because the pages have receipts pasted onto them.

On the old 6015 you could scan multiple pages to single PDF. 

In the new 6027 I cannot find an option or way to do this. On Xerox MFP mahcines there is "job function" that you turn on or off. On this 6027 I cannot find. I am scanning to PDF which is a format that will accept multiple pages. 

Any advice on how to solve would be appreciated.
