Hi: I just received an Officejet Pro 8600 Plus for office use. I installed for use with my iMac - printing is working fine, but when I scan or copy it prints an entire page of vertical lines. Hundreds of them. You can't make the copy out at all.
I have tried many of the steps in this thread - unplugging for 5 minutes, unplugging from a surge protector. Nothing has worked.
Thanks for your help.
