Scanned images 'scrunched'?

[Quofalcon]

For you scanner users, this question is for you.
When I scan some of my traditional lineworks lately I notice the image is decreased in scale (scrunched as if it were) in height, making the image slightly squashed and well fugly. I use a Microtek scanner and pass the image onto photoshop for adjustments. Now this doesn't seem to happen all the time but lately I'll notice it right away from the moment I do a prescan in my scanner's main window program before passing it onto an image editer.

To fix this I normally just up the pixel/percentage of the image's height by 10% or so and get it as close to the original once more... Now, does any of you scanner users have any idea what causes this or how to fix it from happening all the time?
Much appreciated!

Does the scanner have an 'manual' mode? Auto mode would be were you just hit the scan button and it does everything for you. Manual mode would allow you to change all the settings to get a better scan.

I think there may be some default dimensions that the scanner is trying to fit everything into, regardless of the size of the medium being scanned. Have you checked out the settings at all?

I have everything set to default or which is 'no adjusted auto' settings that I am aware of. My scanner takes 9x12" scale and often is the size I use for scanning works.

Could it be that when you open it in photoshop that the pixel aspect ratio is wrong? Doesn't sound like that kind of problem, but you should check out if anything happens when you go to: view / pixel aspect ratio correction. If there is a check next to pixel aspect ratio correction try to uncheck it and see if anything happens.

In photoshop but I normally see the problem beforehand when I am in my scanner's main window. I'm going to check it out this evening when I have the time.
