Sony PRS ghosting problem ?

I'd like to know if I am the only one to suffer of Ghosting with the new PRS-650.

I attached a 3-page PDF, so you can test your reader.
The first page is a black page.
The second page is a page with some black boxes.
The third page is a white page.

When you open the pdf, you see the black page. Go to next page (the page with the boxes). Then go to the third page. Are you able to see the boxes on the white page ?
I do ! (it may be hard to see, but it's there)

It seems the screen refresh does not clear the screen completely. Maybe it is too fast to let the screen refresh. I tested it under normal conditions (temperature, dryness of the air).

When I tap the "zoom" button, then tap the close button, the screen refreshes. I can not see anything anymore *except* for the "zoom" options. I clearly see the close button !

The PRS-600 suffered from the same type of problem. I had hoped that sony fixed it, but it is not the case. It is sad, because when you fast-forward through a book, the last screen refresh after you release the "left" or "right" button does do a true refresh.

Ok, it is light. But on images (in a book with illustrations), it is very noticeable.

Am I the only one ? Are the other models affected as well ?

I don't think the ghosting problem is any bette or worse then my previous 505 or 600.

Darker pictures usually too 2 pages turns to completely wipe away.

Yes, there is a little bit of ghosting, but it goes after a few page turns. Probably about the same as the 505.

I haven't had a chance to test your PDF yet, but I have noticed that in the few thousand pages I've read on the 350 so far, six to eight pages will look ghosted (no pictures, just text). More than ghosted, I suppose -- when I flip to the offending page, the background is much darker and the text of the new page, grey and not anti-aliased, is superimposed over the white text of the previous page. It's like the screen refresh hasn't cleared completely after the black flash. It'll usually go away if I reopen that page again.

I thought it may have meant a faulty reader at first, but if it only happens a couple of times and can be fixed with another screen refresh, then I suppose that's not too bad at all.

Yep, once in a while, but not really an issue.

Yes, sometimes dark elements persist a little, but only for a single page turn. It's not a problem.

flipping a couple of pages makes it go away, so there is no problem here.

Nothing different from my BBMini. It's not annoying and only happens when you have two high-contrast pages (or menus)

Well. When I read a book with some pictures, the text from the previous page is clearly visible on the picture.
It is annoying, because, I have no way to get the image displayed correctly. Since the next page also contains text, when I go back to the page with the pictures, the picture still has some shadows over it.

It annoys me because it is so an expensive ebook reader and I'm sure it can be corrected by software. But as most of you are saying it is not a problem, i guess Sony will never work on it.

But now, I know that my device is not faulty, so thank you !

Press the zoom key, then cancel it. You'll still get a bit of ghosting, but not a whole page's worth.

It is inherent in eink displays. Goes with the territory.

My PRS-505 has always had a ghosting problem. I just figured that this was inherent to e-ink screens. It's a bit like reading something printed on really cheap newsprint where the ink from the other side of the paper is visible. I find e-ink very poor for greyscale graphics. Nevermind the restricted levels, the poor contrast will make images look like very poor newspaper images.
