Communication of copied facts (3)

I believe the answer is:

fax

I'm a little stuck... Click here to teach me more about this clue!

'communication' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for fax that I've seen before include "Transmit document" , "Means of communication" , "Electronic transmission" , "Modern method of transmitting printed matter by phone" , "Transmission of exact copies of documents electronically" .)

I've seen this clue in the Evening Standard.
