Looking at the diagram for the Power PCB (printed circuit board) at the link you provided, it appears that there are five fuses, designated F1 through F5, which are located on the left half of the board, and as Gs5556 suspected they are probably soldered onto the board. All of them are rated at 50V and either 2 or 2.5 amps. I don't see any mains fuse.
If you look at the photo of the unit, on the left side you will see the AC hot and AC neutral wires twisted together and running to near the front of the unit, where they are connected to what appears to be the "PSW" PCB. A black flat-shaped cable emerges from that board and most likely goes to the Power PCB, which is probably located under the transport mechanism, extending toward the rear and probably extending under the small board or boards that can be seen near the rear center.
The bottom line: You would have to disassemble most of the unit to access the five fuses, and you may have to do that on both the top and the bottom in order to be able to unsolder each of them and solder in the replacements. Not something I would want to attempt, and I consider myself to be fairly adept at doing that sort of thing.
