HP Photosmart c4680 scanner and printer

All the details

Scanner works perfectly. Printer probably works, but the rubber roller which pushes paper through the printer has stopped gripping paper and I don't have the time to work out whether (or how) to fix it. Comes in the original box with the cables, power lead, manuals etc. Looks like it is in perfect condition from the outside (but clearly a lot less useful with the rubber roller not working).
