This summary is not the rule. The rule text controls.
Here's a plain English summary:
If you have a copy of a document instead of the original, you can usually use that copy in court just like it was the original. This includes photocopies, scans, or other exact reproductions. The court does not normally require you to track down the original document to prove your case.
There are two situations where a copy might not be allowed. First, if someone raises a real doubt about whether the original document was genuine or authentic, the copy may not be good enough. Second, if using the copy instead of the original would be unfair for some reason, the court can refuse to accept it.
In practical terms, this rule saves people a lot of hassle. You do not need to worry about losing an original document or keep it locked away for safekeeping. As long as no one seriously questions whether the original was real, and using the copy would not create unfairness, your copy will work just fine as evidence.
