Separating a working scanner from its broken printer

The laser printer portion of this all-in-one machine gave up the ghost and [Entropia] couldn’t get it working again. But the scanner was still functioning so he decided to separate the scanner from its dead printer module.

The model in question is a Samsung SCX-4200. The design is actually perfect for separation because the scanner sits on top of the out feed tray of the printer. It can even be lifted to allow more room for printed pages to pile up. All he has to do is separate the hinged connector and reroute the flat cables. But the real question in [Entropia's] mind was whether or not the control board would work without the laser printer components connected to it.

He carefully┬ádisassembled┬áthe unit, spilling toner here and there which is left over from a catastrophic knock-off toner cartridge incident. A quick test showed him that although the drivers complain that the paper tray is open, the scanner does still work. He glued the controller board seen on the left to the bottom of the scanner enclosure, and added some felt feet. Now his scanner is closer to the size you’d expect. And on the plus side he gained a geared stepper motor, laser scanning unit, exhaust fan, and a couple of solenoids to use in future projects.

  1. Nice to see it not going in the bin. in the long term I’d removed the stock power supply. as the HVPS and Fuser switching parts of the stock power supply are no longer needed. pinouts are usually pretty extensively silked on samsung printers so figuring out the photo interupter and door switch functionality should be relitively easy.

      1. You may think that’s funny, but honestly it’s ridiculous :( My Canon all-in-one does this and I wish I knew how to hack it so that it wouldn’t.

  2. buy a new scanner for 50$, seriously how do you justify spending such a rediculous amount of time to make some obsolete garbage resolution device, how much is your time worth?

    1. This is comedy gold, I hope LOLs comment stays up.

      I can imagine the new title:
      “All-in-one with broken printer, working scanner, tossed in favor of buying a new scanner”

    2. Admittedly the scanner isn’t as good as a dedicated scanner but I’m not working in the graphic design industry either. SCX-4200 can scan at 600 dpi with some noise, and that’s more than good enough when you scale it down to 300 dpi.

    3. If hacking the solution together was fun then the time was well spent. Simple as that. The task can be its own reward.

  3. I have a cannon multifunction mp258 printer. The scanner wont work without catridge installed. Can i separate it in the same way so that at least scanner can be used?
