Page copiers producing documents (6)
I believe the answer is:
papers
'documents' is the definition.
(I've seen this before)
'page copiers' is the wordplay.
'page' becomes 'p'.
'copiers' becomes 'apers' (ape can mean to mimic or copy).
'p'+'apers'='PAPERS'
'producing' is the link.
(Other definitions for papers that I've seen before include "Identifying documents" , "tabloids, maybe" , "Print media" , "Documents; the press" , "Documentation" .)
