Hi there I have a 3 year old iMac running Lion and have been using an old Canon N1240U (aka LIDE 20) to do ad hoc scanning with. Nearly all my scanning is document scanning, medical and financial records, usually of one or a couple of pages in length per doc (so sheet feeding is not totally essential), although I have to scan a couple of 20 page documents, but this wouldn't be the norm and if the scanner is quick enough, a flatbed might still do this without being TOO much of a pita. In the future I will need to scan receipts but this is not an immediate requirement. I am trying to go paperless at home. I generally use 600dpi 8 bit greyscale and 'Text' mode on Vuescan to get the best scans at not too large a file size. I have tried 300 but it isn't quite good enough. 1200 is not significantly better than 600 to merit the extra file size. I view the documents on screen mostly. They are important docs so I want a really good quality if possible. I know most people use 200 or 300 dpi for document scanning so it would seem. I am looking to upgrade to something faster and preferably giving me as good scans if not better. I've looked at some of the Canons like the LIDE 210 and it doesn't seem to be any quicker in terms of its msec/line rating at 600dpi than my existing scanner. I am not sure whether to go flatbed or sheet feeder either. Ideally I would buy a high quality flatbed and also a robust high quality document scanner but right now I can't afford to do both and could only stretch to a relatively high end flatbed or a cheaper sheet feeder. The Epson V330 could be one option, but it's 2.9s/line rather than 5.3 of the Canon so it's not HUGELY faster. The quality is supposed to be very good though. I was also considering something like the Canon P-150M which is much cheaper than say a Fujitsu S1500 or an Epson GT-S50, but not quite as fast or possibly robust. I hear it also skews but that might only be an issue later when it comes to doing receipts. I assume that no ADF will ever produce as good scans as a good flatbed like the V330? I guess it would match the quality of my LIDE 20? Any input you might have would be greatly appreciated. Cheers!
