Title: Edge Scanning
Post by: Bear78 on January 31, 2019, 03:56:12 PM
In another thread I got asked me about my scanner which in turn, got me thinking about my scanner. When using the built in plastic guide on the scanner, it cuts off a tiny bit of the edge of the scan.  This is why my scans are always "in the middle" of my scanner and usually not straight (despite my best efforts trying to get it straight as possible). ANYWAY, what I'm getting at is has anyone found a good way to correct this?  I was thinking about getting a L Square (something like the link below) to stick in the corner.  Any ideas?

I've been working on this guide for the VGPC Scanning Project you might like - http://wiki.vgpc.net/index.php?title=Scanning_Guides

I use this https://www.amazon.com/gp/product/B007MUO8K4/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 for my square on my scanner. Works great for boxes but not manuals. Also had to trim it down but wasn't too bad.

For manual pages I used bandaids. They don't get things exactly straight but they do good enough imo.

I basically made my own L-square out of a manila folder.  I used a manila folder because it's thick enough to be sturdy and used multiple times, but thin enough to lay flat with the cover I'm scanning.  It seems to work for the most part.  It definitely keeps the scan away from the edge so you don't lose any part of the image, and it makes it easier to keep it straight.  It can still be a challenge because sometimes stuff likes to move as you close the cover.

The issue I have with most actual L-squares is that they are either too thick or too large.  Also, if they are made out of metal, they have a good chance of scratching your scan bed.

Thanks guys.  There's got to be a plastic square out there that would work for this.


This seems like a perfect thing for someone to 3D print maybe lol

Sounds like this might be a good plastic one but might be a little thin:

Obviously the issue with 3D printing would be the thickness.  Can you 3D print something that thin?

Here is a picture of what I made.

That's a good point.  Hum, maybe I'll mess around with some materials I have at home and see if something works.  If not, I might try that plastic on from Amazon.

Give me the dimensions and I can just laser cut something out of whatever material you want.  Will literally take less than a minute ;)

Yeah the metal squares are really only good for boxes due to thickness, and yeah you have to be careful not to scratch the scanbed.

I would love something very thing but heavy enough to keep manuals straight. Haven't found anything yet though :(
