Trouble Scanning Multiple Pages on Dell All in One

Hi,

    I am using my Dell All in One 946 strictly as a scanner.  I do not have ink cartridges in it.  It is attached to my computer which has Windows 7.

    I have no problem scanning single pages because when I get the "Right Cartridge Missing" and "Left Cartridge Missing" messages on the machine, I just click the check mark and move past them to Scan Mode.  For some reason, when I get to "Scan to," a "Downloading Applications" message appears, yet nothing is ever downloaded.  This does not prevent me from making single scans.

     I cannot not find the "All in One" Center that is mentioned in the manual.  Would anyone know why?  I tried to follow the instructions on  p. 50-51 of the manual, however I cannot check a box that says "Scan multiple items before output,"  if I cannot find the Center.

     Can anyone suggest a way that I can scan multiple pages by loading several document pages into the ADF imput tray?  I would really appreciate  help.  I am a senior, so please keep it simple.  Thank you in advance.
