I had an HP4550 printer for years that I picked up at a liquidation event. It has been a workhorse but it died in the last 6 months, some ugly hardware problem. The cost to fix would have been 4x the cost of new printer so I just decided to junk it. The problem is, it is huge and weighs like 100 lbs and the recycling guys would have laughed at it. So I spent sunday taking it apart — taking every screw out, every piece apart. My gosh I now understand why this thing was so freaking expensive, hundreds and hundreds of screws and parts. It is now a giant pile of scrap metal and plastic that I can fit in the recycling bin and get rid of. I have new appreciation for the recyclers of the world.
