Review on 🖨️ VIISAN 3240 A3 Large Format Scanner | High Resolution Color Scanner for Receipts, Documents, Photos, Books, Art, and CAD | A3 and Below Flatbed Scanner | 2400 x 2400 DPI | Fast 4 Second A3 Scans | Windows & Mac Compatible by Doug Virden

So far I find this scanner ambiguous. I'm using a Mac and am still learning some of the features. I think a lot of the instructions are for PC users, which is useless, but I use one of the main Mac utilities, Image Capture, as recommended in the 'read me' file that came with the software download (there is no floppy drive on my iMac, so the installation disk is useless). Image Capture works great with a scanner. I still haven't figured out how to activate the buttons on the scanner itself, but I haven't tried very hard yet. I love how big the scanning area is and how quickly I can digitize old sheet music or scrapbooks. And I love that you can scan as many pages as you want into a single PDF - I wish I had found that out before I scanned the 100 JPG files I need to convert! What I really hate is the sound it makes. I find it loud and shrill and it's guaranteed to give me a headache. But I've found that with a pair of in-ear headphones and good music, the sound boils down to a low hum, and I'm fine with that. I really haven't seen many other options that fit the bill. It does what I need it to do, fast and well, so I'll definitely be buying it again.
