When printing or copying the ink can be rubbed off, this is usually down the middle of the paper. Any idea which part is at fault, jets, imaging drum ?

This is a problem with the fusor not heating in the middle for some reason. Either the fusor roller is damaged or the heating element is.
Toner is not like ink, it has to be heated onto the paper.
Take a good look at the roller...if it's not damaged, then the fusor itself has a problem and the unit in either case must be serviced.

I need to load paper and I can't seem to be able to follow the instructions on the paper tray very!

The 2840 can have an optional paper tray at the bottom of the printer.. perhaps that one is empty?
Otherwise, you place the paper on the open tray that drops down in front when you open it, and extend and adjust the guides.

A tech needs to look at it. It could be as easy as just reseating the 4 wire bundle connector that comes off the scanner and connects to the formatter.
But, in any event a tech has to check it out.

Fusor error

according to your name I almost an convinved you are from Holland? heb ik gelijk?

This links will give you the answers you need. I guess it is an installation problem which will need for you to un install and re install your drivers.
otherwise it might be the fusor fan which is stuck which requiers you to clean it.
please try this link and if it helps please rate me as FIXYA.
