How would one write "face up" (e.g. as an instruction on a copier)? We are trying to solve a minor mystery over at Japanese.SE: I found a multifunction printer/scanner/copier/faxer that had the following instruction label on it.



Curiously, the last two lines are both in Japanese. The first one, 原稿面上向き genkou-men ue-muki, means something like "document face-up"; and the second one, 送信面上向き soushin-men ue-muki, means something like "the side you want to send face-up". 

User Earthliŋ's suspicion is that one of these lines was supposed to be in Chinese, perhaps as 原稿面向上. From the perspective of the device manufacturer, that certainly seems reasonable. 

On a linguistic basis, though, does that seem plausible? Does either of the two Japanese lines resemble what a Chinese device would use to indicate "face up"? 

(Note: my knowledge of Chinese is virtually nil.)
"Face up" in Chinese is 面朝上.





An example sentence:

Place your card face up on the table, please. 

请把你的牌面朝上摊在桌子上。 



面向上 is also OK. 





From the Japanese alternatives, perhaps the first one would be more intelligible in Chinese, but with 上 at the end of the expression.
