Hi GRBradford
Suppose there are 3 signers on the document Signer1 (Sign's electronically), Signer2 (sign's manually) and Signer3 (sign's electronically).
Now you have setup the document on the send page entering the signers email address in the sequence you want them to Sign the documents and paced the Signature fields on the document for all the Signers.
Signer1 will receive the document for Signature, he will click on the link in the email to sign the document.
Now, Signer2 will receive the document for the Signature, signer will not click on the link to sign the document and download the document on the System and print it. He will sign the document manually and then scan the document and send it to you via email.
Now you will have upload the manually signed document in your Adobe Sign account on behalf of the Signer, navigate to Manage page - > Select your document under Out for signature, click on History -> click on upload Signed copy to upload the document.
Once the above steps are done process for the 2nd signer gets completed and the document is send to the 3rd signer for signature.
Feel free to reach us back if you have any query or concern.
Regards,
Aadesh
