Company support for office machine (6)
I believe the answer is:
copier
'office machine' is the definition.
(I've seen this before)
'company support' is the wordplay.
'company' becomes 'co' (abbreviation).
'support' becomes 'pier' (pier is a kind of support).
'co'+'pier'='COPIER'
'for' is the link.
(Other definitions for copier that I've seen before include "Something that duplicates" , "Office machine" , "Machine for reproducing something" , "Reproducer" , "unoriginal type" .)
