Scananner Split
To do: figure out why, when settings are identical, one scanner produces the gritty, low-res scan on the left and the other produces a pretty close facsimile of the actual sketch.

The left-hand scanner is the big one, the 11X17. I got it because I work bigger than letter-size most of the time and I dislike piecing scans together. I usually have to do a lot of work with its scans to make them satisfactory.
The right-hand was a cheapie scanner I picked up on a whim maybe five years ago. It has been stepped on (trod upon, for my friends across the pond, and also Trev and eFlo,) knocked to the floor by the kitten; it definitely has rattling pieces inside it somewhere, but it still works terrifically. It’s just small.

LOL…that’s so funny. I have the same situation. My old, very small, outdated scanner gives me better scans than any professional one at work, hands down. Of course there is the problem of having to scan a piece 4 or 5 times to get it all…heh heh. But the joy is in the journey, eh? That’s the theory anyway.
Nice to know I’m not alone, man.
Are they the same brand scanner? Do you scan to a file, or scan into Photoshop, say? I’m imagining that maybe it just has to do with the internal calibration of each scanner that handles the same scan settings differently. I have two identical scanners (one is flatbed and the other has a batch feeder) and with those two I can use the same settings & get the same results, which is to be expected, considering they’re the same thing. Or, maybe it’s not to be expected, and I’m just lucky! It’s also just occurred to me that maybe you were asking a rhetorical question and here I am getting all rain-man about it. At any rate, sounds like you need a set of big scanner settings and a separate set of small scanner settings.
Ain’t technology grand?
I do scan into Photoshop. Maybe that makes a difference? They’re different brands, so that’s probably causing some issues.
I think the main thing going on is that the biggun (the one on the left) is just a cheap, bad scanner. Get what you pay for, a wiser person than myself has been known to say, even when it’s not an appropriate cliche to invoke.
Thanks for the ideas on the settings and stuff, Kelly. Man, I’m teh suck when it comes to hardware.
It’s retribution for you wearing Red Sox attire.
