set up speed dialing
Through your HP OfficeJet or your computer, you can assign entries to fax
numbers you use often. This lets you dial those numbers quickly using the
front panel’s Speed Dial button or one-touch speed-dial buttons. You can
create up to 130 individual and group speed-dial entries (varies by
HP OfficeJet model).
You can use speed-dial entries only from the front panel.
