We have been having the same problem with a
Microtek Scanmaker 4. I swapped the original unit
with Microtek (an extremely lengthy and unpleasant
adventure, I must say), and just received the new
unit this morning. My user hooked it up (to a Mac
G3, 128 MB RAM) and we have exactly the same
problem we started with.

These lines appear at regular intervals down the
entire scan screen but ONLY when he uses the
Unsharp Mask filter function in the scanner
software. If he doesn't use that setting, but uses
Photoshop's Unsharp Mask settings to achieve the
same result, he get no lines.

So do I get back on the merry-go-round with
Microtek "tech support", or is the culprit my
user? He's used computers before, you know, so he
doesn't need help setting anything up.

Thanks for the reply Jackie.  I'll have another look at the way I adjust my
images.

Hello Brian
All it takes to cause vertical lines is just a small amount of liquid to get
under the calibration strip.  Some glass cleaners will cause the very edge
of the plastic underneath near the glass platten to shine during
calibration. This in turn will not allow you to scan the full width of the
bed without noticeable lighter vertical color bands on the far right and far
left edge.  As always, its better to spray the cloth and not the glass. And
try not to get any on the plastic either. Of course, manufacturing defects
could cause stripes too.

One last point while I'm at it.  Scanners should always be place on a hard
level surface.  If not they will conform to the irregularity and the scan
image will be distorted. After all, they're mostly plastic shells. My 9600XL
is solid but still will flex if not supported properly.

Try this:  Place a small photograph on the glass on the far left. Prescan.
Now draw the marque box around the image. Scan.  Now place the image on the
far right and prescan. Simply drag the marque without resizing it over onto
the prescanned image. Scan. Now look at both of the results.  If your
scanner isn't sitting flat as it should both images might look as if the
upper and lower horizontal edges aren't parallel. Also. the second image
might look as if you drew the box too small or too large after prescan.

Sorry for the long winded stuff. I don't post to this group often so I
figured I better say it all right now.
