If you have not done so,

Open Printer Tray / Remove / Reload the paper into the printer

Use the printer display to update modify the paper size / type

AND / OR

Use the Embedded Web Server (EWS) from your browser use HP Smart to change the paper size.

Reminder

HP Smart Mobile requires that you adjust / correct the paper size and type before opening the content to be printed.

Adjust / Edit / Modify Paper Size & Type

Open Printer Tray,

NOTE

If you are having trouble with getting the printer to accept (new) paper,

Remove the stack of paper from the tray

Lightly flex (do not fan) the paper to separate the single sheets

Re-stack together so the edges match along all sides

Return the paper to the tray

Wait a few seconds

Close Tray

Check / Adjust / Retain the Paper Size and Type at the Printer Display Panel
