Incredible. Two pages of detailed schematics on how to open the printer and turn on a tiny switch
And then, at the end of the section, at the bottom of page two, a block of warnings ranging from
"When the peeler is switched off, the peeler does not work"
to
"The print head gets extremly hot while printing or after the printing, this can cause serious burns. Do not touch the print head"
