Repair guide for hp photosmart c410b

Hi don't suppose anyone can help me I need to take apart my hp photosmart premium c410b printer to do a few repairs and also to fix the gear that feeds the paper roller it had moved I'm guessing worn i used a small amount of epoxy resin mixed together but I'm in a bit of a dilemma I cannot remember what different parts go where? Would anyone have a guide or YouTube video to help me I should of taken photos before stripping down the printer.

Amy help much appreciated.
