Original copies of what, your file videos on the USB memory stick? Go to the support site Joel_Ek provided. If you have deleted clips in the cloud on the app, they are gone in the cloud, Blink will not recover them. I assume you know clips you want to save can be downloaded on your phone.
I don’t think Blink provides printed manuals. None came with the Blink cams I bought, just a quick start guide. These days a lot of products no longer come with paper manuals, people download them online. As Joel_Ek said the support site IS the owners manual. You could print pages from there if you want.
