Copier paper unwrapped (3)
I believe the answer is:
ape
'copier' is the definition.
(ape can mean an imitator)
'paper unwrapped' is the wordplay.
'unwrapped' says to take the centre (the letters which wrap the word are removed).
The middle of 'paper' is 'APE'.
(Other definitions for ape that I've seen before include "Copy - primate" , "Anthropoid primate" , "Large primate" , "Idiot" , "Imitate like primate" .)
