We also have the Fiuitsu iX500 SnapScan as our primary scanner. Do you remember switching printers from a single tray to a dual tray? This iX500 is just as dramatic an improvement to your operation! First, the device is easy to install and use. I take on those scan back (fax backs) without dreading the additional time and focus in preparing my scans. It is a top feed table top machine that advertises that is will scan 25 pages per minute. When I began using mine, I was limiting myself to no more than 30 pages per pdf file. As I began testing the limits of this workhorse, I increased the amount of pages per attachment to 80. It scans BOTH sides of each page automatically which makes it even more useful when you are faxing disclosures for overnight sales. Yes, it is a bit pricey but we trust Fijitsu brand and the investment is well worth it as you can walk away from the device while it is scanning your docs. I used the eFax system years ago and abandoned it because of the fee increases. This is your solution to scanning problems.
