I'm still sticking with it. It's an intermittent problem. I'm not printing a lot now so I either reprint a couple if I have to or cut off the white edge. Not ideal but works for me since I've recently only been printing for friends and family.

Thanks for all responses.
After keeping it going for this long- cleaning pads with Windex to eliminate clogging, adding a waste ink tank etc- I thought I'd keep it going forever. Don't like to give up, but it's time.

 Thanks for the response.
The areas that are blank at 1 or both ends of the 4x6 prints are actually cropped off. It appears that the printer starts printing too late or stops printing too early during receipt of image. If there is blank space at one edge,the print doesn't just run off the other end. Don't think this is a paper feed issue because paper always feeds properly-but could be.
 I might have to get another printer. I'd buy the 1900 but I believe the ink carts are even smaller than on the 800/1800. I'd get the 3800 except I'm concerned about gloss differential.

Too many choices!

I've used this printer for 5 years and have recently developed an intermittent problem with borderless 4 x 6 printing.  At times it leaves a blank non-printed area (about 1/8 inch) at the back edge or more recently the front and back of the print. The long dimension is fine. This will happen randomly in a batch of prints. If I reprint the same photos they will often print OK. I know they are cropped properly. Any insight into the cause of the problem would be appreciated. Anyone else have this problem?

I am using a PC with Windows XP Pro and Qimage Studio Edition. All other printing including CDs OK. I don't do larger borderless prints - so don't know if I would have trouble with them. I've resolved a lot of other issues with the printer and otherwise I'm very pleased with the prints.

Thanks for your help!
