This message pretends to be an email message sent by a multifunction printer/scanner/fax machine as the result of scanning a document. The message claims that the document is a PDF, but the attachment is actually a ZIP archive (note the extension at the end of the file name). The key principle here is that any message you weren't expecting should be regarded as suspect--if you didn't just scan a document, why would you be receiving this? If you aren't sure, don't click on any links or open any attachments.
