KK: /ˈfoʊtəˌkɑɪpər/
A device that makes copies of documents and images by using light and heat to reproduce them on paper.
The office has a new photocopier that can print in color.
Photocopier → It is formed from "photo-" (from Greek "phōs", meaning light) and "copia" (from Latin "copia", meaning abundance or supply). The word refers to a machine that uses light to create copies of documents, thus producing an abundance of reproductions.
Think of 'light' ('photo-') being used to create many copies ('copia') — that's how a photocopier works.
