the problem, joel_lama2001, i am sorry to say, is that, like all of us here, you have bought HP and should not have...
now apparently some have overcome the problem by disconnecting the thing for some time - and probably sacrificing some animal under a full moon.
but most of us are stuck with the sad realization that their scanner has a factory defect that HP wont recognize.

I repost this from a comment I made almost one year ago...the fix still works 100%

I think I solved my own problem and I want to share the results.
The printer was sharing an extension cord with a paper shredder, both sharing a surge protector. Shredder is located about 2 feet from the printer.
I kept the printer on the surge protector, but I moved the shredder to a regular wall outlet. I also unplugged the printer for about 30 minutes. I never physically moved the printer or shredder however
The problem has gone away.
I am guessing that the electric noise from the shredder was getting into the sensor on the printer that is used in the copy and scanner modes.
I will monitor this fix, but for now I think I have found the problem and the solution. i hope this helps someone else out there,since the printer is very good.

I wrote in another message stream last year about this. The CCD sensor that scans the page is sensitive to electrical noise. Do not have the 8600 share a plug or power strip with anything that has a motor, such as a paper shredder. The noise builds up on the CCD and that is why unplugging the 86000 and waiting a few minutes also cures the problem....the electric noise on the CCD dissapates.
Those old enough to remember the old TV system will remember the video noise that was on the TV screen whenever Mom ran the vacuum cleaner. This is the same kind of electrical noise

BS, I have tried every tip that was given on the six pages of suggestions and nothing works. It works fine when I put the pages in one by one, but who the heck has time for that.
