My Epson model is a V37 and one thing I have discovered with it is the space between the glass and the reader is not accurate and creates the label image to be marginally oval shaped rather than round. By lifting the record a small amount above the glass I get round images and when I lift slightly higher again they become oval again in the opposite direction.

Regardless of all that I have not had a blurry image. The settings I use are:
Mode: Professional Mode
Document Type: Reflective
Document Source: Document Table
Auto Exposure Type: Document
Image Type: 48-bit Color
Resolution: 400 dpi
Documint Size: A4 (default)
Trimming: On
Unsharp Mask Level: Medium (Box not ticked)
Descreening Screen Ruling: Magazine (133 lpi). (Box not ticked)

Hope this helps.

It might be worth adding a note for newbies to the "guide to adding images" instructions, to state that labels should be cropped to a circle prior to uploading. I only joined this group a few days ago and I have uploaded over 50 uncropped label images so far... I assumed incorrectly that there must be a template applied post upload (along with automatically resizing the image). I will make sure that future uploads are cropped and edit the ones I've done so far but I did read the instructions (below) and if it had said to crop in there it would have saved me some grief:-
