Photos taken on zoom have white horizontal lines across them. Photos taken at normal zoom are OK.

this can be usually associated with your white balance in still camera mode.
Check to see your white balance is set correctly or just set it to auto. Also make sure the mode you are in it set. (ie. indoor, outdoor, auto, speed)

Try using the HP Print Diagnostic Utility in Windows - HP Customer Care (United States - English).

> I bought a new printer

Take it back, and get one that does work correctly.

> VERTICAL lines ACROSS the whole photo

Hold the paper in "portrait" mode, not "landscape" mode.
Are the lines HORIZONTALLY-ACROSS the paper,
or VERTICALLY-DOWN the paper?

If those lines are WHITE and HORIZONTAL,
then some of the many ink-jets inside the print-head are *CLOGGED*.
Run a "print-head-cleaning-cycle" to try to unclog it.
Or, exercise the WARRANTY, and get it replaced.

your shutter is not closing over the lens completely. try taking video, that should be ok. your lens will have to be stripped down to clean the shutter

lence lip crake 

If the photo shoot out show white , the obscure (quality variation), and even horizontal line ( white lines), and so on over-exposure cases, even if the use of anti-tremor, set to default values are invalid, because the camera shutter fault.

Can't repair by yourself.
It's need repair camera machine shutter.

Ok, first of all......when you transfer the pictures to a computer are the blue lines still in the picture? Also if you reset the camera does the image still come out white?

A lot of times what happens is that there is nothing wrong with the actual picture it is the lcd. When you transfer the picture it looks ok you are only seeing the blue lines on the lcd. That means that the lcd is going out. If you transfer the picture and the blue lines are still in the picture after transfer then we can try to reset the camera as there is something else going on besides the lcd. More that likely it is just an lcd that needs to be replaced.

With a white image that usually means that the white balance is off on the camera. I would recommend resetting the camera and then try retaking some pictures to see if they are still coming out white. If they are then you would have to send the camera in to be repaired.

It is the shutter (or at least it was for me) I found a simple test here: http://www.mydc.com.tw/repair/knowledge_en/casio-exilim-ex-s600-overexposure-t17.html
I repaired it myself, but it took me a whole afternoon and lots of patience.
The hard part is taking the camera apart, once I got to the shutter I just activated it manually so to dislodge any pieces that might have gotten jammed, then placed it back together again and it worked! :).
It's really hard to take apart, it's like a puzzle sometimes, to find which screws are keeping it together. I also had a bit of hard time when it came to put the zoom back together again.
But I guess it beats throwing the camera away.
I'm still puzzled on how the CCD works so that an overexposure would make horizontal overexposed lines, but everything points to that. Fixed shutter, lines be gone.

Contact Nikon on thier website, they will send you a reply and a link for return service and fix it for free. This website is no help, they want you to subscribe to a service before they reveal any info.

I also have the same problem! I absolutely love this camera but suddenly out of the blue I have stripy lines on the screen that look like you are looking through a venetian blind. I have contacted Fuji but they say it will cost £99 to repair or have offered £50 discount on any other camera. I just want my F460 working ok. Please, please can anyone help us?
