Beginner HP Colorspan DisplayMaker 72UVX questions

I wanted to see if there was anyone out there that would mind answering some beginner questions on the Colorspan DisplayMaker 72UVX.

I was given a 72UVX, but have some questions on how to set it up. I found some manuals on HP's site, but I still have questions.

For example, I haven't found a manual that shows what the two 'parallel' type cables that go out of the left and right sides of the 'printhead' I guess you would call it - are for... What they connect to.

Thanks
John
