I use an epson perfection 4870 photo. the images are usually soft. is
this a common complaint and is there any way to enhance the sharpness
other than the unsharp mask filters? thanks in advance.

I just bought a epson 3490, it is the first scanner I have used and I
thought the same thing. I wondered if some units are less sharp than
others. I put up some samples at http://harv100166.tripod.com/scans.
Original sharp edges seem to grade over a number of pixels.
Then again maybe it's normal.
 
In general, most all scans will need a bit of unsharp mask to bring back the
sharpness. Dedicated film scanners normally don't need much, flatbeds
usually always need a significant amount. Less expensive flatbeds will need
even more :( That doesn't mean the final output is necessarily poor, it
will just take more effort and skill to produce the desired result.
Depending on the optics for your particular scanner, you may find that
changing your holder height by shimming will give you a bit of extra
sharpness. Wet mounting may provide enough benefit to be worth the extra
effort with certain films.

The "Warranty" and the "fiver" snippet are certainly blurier than normal,
indicating either a defective scanner or mis-focus, possibly because the
source was not flat against the scanner's glass surface. Your result should
have a slight unsharpness, but not to this extent.

On the other hand, the scan of the full "fiver" is good and what one would
expect, indicating that your scanner is fine. If you were scanning images,
6000dpi is much too high - scan at 300dpi for print. 6000dpi is for
negative and slide film.

To compare, I scanned a US $1.00 bill, and posted the unsharpened scan and a
sharpened version at

http://www.photo.net/photodb/folder?folder_id=600929

It was scanned at 300dpi on my old Epson Perfection 1200 Photo scanner.

well, I returned the scanner, received a replacement, did the same
scans and got exactly the same results,

it has nothing to do with the source flatness or height, because I
tried elevating the print by 2mm, it makes no difference.

if anyone can point me to any other similar text or detail scans on the
web I would be grateful.
