If you have not done so, consider updating the Firmware
HP ENVY Photo 7800 All-in-One Printer series Firmware Update
What else?
Having read all the same information to which you have access (how-to, troubleshooting, user guide), and assuming you are not faxing across some kind of date line, I cannot find a reason for this other than the date/time/zone needing to be updated / corrected on the printer.
This doesn't mean there is not another reason, of course - it means I don't see one.
Example
Embedded Web Server (EWS) - Manage Printer Date / Time
NOTE: Your printer may present this option differently.
Open your favorite browser > type / enter Printer IP address into URL / Address bar
Tab Settings > Preferences > Date & Time
EWS_9025_Date-Time_1
Printer Home Page - References and Resources – Learn about your Printer - Solve Problems
“Things that are your printer”
NOTE: Content depends on device type and Operating System
Categories: Alerts, Access to the Print and Scan Doctor (Windows), Warranty Check, HP Drivers / Software / Firmware Updates, How-to Videos, Bulletins/Notices, Lots of How-to Documents, Troubleshooting, User Guides / Manuals, Product Information (Specifications), more
