Have you not had this conversation before about where your scanner stores it's files?
With my Epson and Samsung printers they, by default, create a folder in the My Pictures library and I would imagine that is where Brother will also store the scans. But at some point in the scan process or settings will be an indication where the scans are placed.
Well, looking back at your previous threads, you haven't got the hang of it yet ;-) Maybe this will help as it is the instructions with screen pics. (I'll put the link at the end of my post as pca formatting seems to chop off any of my text after I've posted a link..)
Locate files scanned with ControlCenter3. Note the instructions at step 5 and 6
5 The Destination Folder field will display the default destination for all files scanned with the Scan to File button. You will need to open this folder to view scanned documents
6 To change the default Destination Folder browse to the location you want to save your files and click OK. All subsequent scans using the Scan to File button will be saved in this location
Sorry for being a pain in the butt chaps but this is what I have been doing so far
Clicked on configuration and chose destination folder which I had just created within my documents.Clicked on file scan started
Checked destination folder scanned item was there and it was a jpeg image
Then signed into my email account which is hotmail clicked on new then clicked on insert then files as attachments but the folder I scanned to is not listed
Okay,,, to save hassle, try: Move or copy the scanned .jpg to a folder that is listed.
Open outlook.com > top right, left side of your name, click the Gear icon > select More Mail Settings > under Writing emails, select Attachments > select Always send files as attachments > click Save when done.
Practice by sending yourself an email with an attachment.
It may be some comfort to know that if you are using webmail Outlook.com (hotmail) you are not the only one having problems sending attachments
