HP Officejet 8600 scanner/printer (North Laine BN1)

This is a machine that I have ONLY ever used for scanning and for that during 2 years at uni it performed perfectly. Originally I rescued this from the streets and fixed its printhead problem just so I could use the scanner alone, but I have never bought any cartridges for it (it takes 4). It has on-board wifi and Ethernet as well as USB connectivity. I've just been given a more recent version of the same machine, so this one has to go......
