HP C6180 will NOT scan multiple pages into one file

I have a Macbook Pro, running OSX 10.4.11 (Tiger), and I have owned my HP C6180 all in one for over 2 years. A few months back my HP stopped scanning altogether (it previously scanned just fine), so I eventually uninstalled the driver and re-installed the latest version (driver 9.7.1, which installs version 7.3.14 of Scanpro). It now will scan, but it will NOT let me scan more than 1 page into any document. It always would let me scan multiple pages before I had to reinstall the driver, meaning after I scanned any page from the glass, a prompt would automatically come up saying “Scan another page into document?” with an option for Yes or No. I’ve gone into the HP Scan Pro settings and I see the checkbox option for “Prompt for additional scans from glass” and I’m absolutely sure that I have this box checked.

Yet anytime I scan in a page from the glass, there is NO option for me to scan another page into the document. The first page just automatically comes up in Preview (my version is 3.0.9) as a 1 page .pdf file. This is quite frustrating b/c I still use all the same programs as before (I used the same Preview app previously, and I could always scan the multiple pages in). I’m still using the same OS and the same computer.

Why can’t I scan in multiple pages? Why won’t ScanPro give me the prompt it used the give?

Please help!
