What is the best ADF scanner?

Post by Scanallthebooks » 07 Dec 2016, 10:40

What's currently the best ADF scanner in terms of quality? Speed is not *that* important (although flatbed scanning is waaay to slow...it does need to be ADF!), quality is what I'm after. Lots of people recommending the Fujitsu ix500...but is there a better scanner?

I cannot say what the best is, but I've picked up a couple of used Fujitsu fi-5120c models from my local government surplus outlet, and they work great! The images are very good, they are fast, and do both sides simultaneously. The prices were great too: $25-$30 each! About 10% of the price of a new ix500.

The ix500 is the latest model, and so is probably an improvement in various ways.

The fi-5120c specification shows that it used CCD imaging sensors which are normally considered superior to the CIS sensors shown in the ix500 specification...

Aw dammit, and I just got hold of a cheaper demo version of the ix500 (nowhere near $30 though! :shock:). Anyway it looks like the fi-5120c aren't being sold anymore anyway, and there are no used ones available near me. So...any other current ADF scanners with CCD sensors?

Another problem with the ix500 is that it can only scan in jpeg format, not TIFF. So no RAW format. The software is a bit "simple" tbh considering the price.

What about the other brands...Epson, Canon etc. Are their offerings superior to the ix500?

EDIT: Found this great ADF comparison document: http://www.xeroxscanners.com/downloads/ ... 062714.pdf (full disclosure, it's from Xerox). Lots of scanners with CCD, some even with dual CCD whatever that is. Seems all the mobile scanners are shit, and the office scanners are crazy expensive.

Although the more expensive CCD sensors would generally be considered to produce higher quality output, for your use case of scanning black and white pages using an ADF you might not notice any real difference. CIS sensors require the material being scanned to be in very close contact with the sensor, which would be expected to be the case with an ADF feed mechanism, and the possibly inferior colour rendering again might not to be an issue.

Although in principle the JPEG format is inherently unsuited to rendering images like text that have sharp edges, in practice it usually produces quite acceptable images provided that the compression level is not too high, and when file size is an issue it will normally be about the only practical option for colour or grayscale. If the ix500 interface is limited you might lack the degree of control you would like, though.

Let's say I was to get hold of a Fujitsu fi-7160 with double color CCD sensors and was able to compare it with the ix500 CIS sensors...which comparative scannings would be useful? ;)

I'm thinking paperback page with text, page with greyscale photo, page with color diagrams, page with color photo. Anything else that would be interesting? Let me know. :lol:

EDIT: Btw some epson scanners are listed as using a "CISM" sensor. This is the same as CIS, right? I'm thinking the additional "M" is just for module...which, if I understand correctly, all CIS are.
