Plan Administrator signed 5500 form electronically

Hard as this is to believe, this is the first time this has happened. Instead of "manually" signing it for us to file, the "manual" signature on the form is an electronic image of the manual signature.

I don't think this is any problem, yet I'm uncertain, and I wasn't quickly finding any guidance/FAQ's that addressed this squarely. I'm sure there is, but I wondered if anyone knew this off the top of their heads. Thanks.

So someone cut and pasted a signature?  Yours are the only eyes actually looking at it.  Fax it back to yourself so it gets all blurry ?

I think it was a "docusign" signature or one of those similar things.
