For a photocopier to be able to make copies of a document it needs to scan the original document stores it then start making copies. My assumption was that photocopiers store the scanned original document in a short term memory, I was wrong. Since 2002, digital photocopiers store a copy of the original document in a hard drive not memory (according to the video). Why? I don’t know. I always thought photocopiers don’t store any data permanently but since they use hard drives then they can store as much data as possible. Watch this interesting video to see the risk behind such technology specially for companies dealing with sensitive data.
