Why might this device have both 原稿面上向き and 送信面上向き as equivalents of "face up"?


Recently, I found the following instructions on a multifunction
printer/scanner/copier/faxer:

Curiously, there are two lines in Japanese (as opposed to just one in each of
the other languages): 原稿面上向き and 送信面上向き. I guess these would be equivalent to
"front of the page facing up" and "the side you want to send facing up" (for
faxing), but this appears to be redundant. To me, it seems that 原稿面 would
subsume 送信面.

Is this just an artefact of how this particular sign was translated, or would
devices manufactured for sale in Japan also feature two separate instructions
where an English-language device would just have "face up"? If the latter,
why? (e.g. might there be some sort of distinction between 原稿面 and 送信面 in
Japanese that I'm not aware of?)




My opinion:

原稿面上向き - for making copies

送信面上向き - for sending faxes

I think, this is the Japanese specific they try to explain things as much as
possible, so they introduced both explanations.
