Officejet pro 8600 copying, printing vert. lines and light printing

[brucefl]

I had printed a page and was copying several of it, I used the auto feeder then scanned it, when it printed out it would have about 5 or 6 lines down the whole page and the print was lighter on what it was suppose to be printing?

I tried a few other things and did the same thing.

Then I tried printing from the computer and the pages printed fine. This was just in black.

I thought the ink may be a little low so I changed to a full new cartridge and did the same thing.

Test prints are all ok, just when I am copying, then printing?

Just weird, any help would be appreciated. Thanks
