Were you trying to scan from the printer front panel or using the HP Scan software?
Which email client are you using? Hotmail Outlook, gmail etc?
We just tried scanning from the printer front panel to hotmail and the attachment was there. Similarly, we tried "Scan to email" using the HP scan software and the attachment appeared on the Outlook client as well.
Would suggest if possible to try scanning to another email client, e.g. yahoo or hotmail?
Alternatively, you could use the printer Front Panel and select "Scan to Memory Device" (USB Thumbdrive) and attach it as a file to your email.
The scanned document would be under "HPSCANS" folder on your Memory Device.
Hope that helps.
