• Check to see if the ring pattern is set correctly. If you subscribe to a 
distinctive ring service through your telephone company, check that the 
HP Fax ring pattern is set correctly. If you do not subscribe to a distinctive 
ring service, make sure that the ring pattern is set to All Rings. For 
information on setting the ring pattern, see change the answer ring 
pattern (distinctive ringing) on page 26.
• If your HP Fax is on the same phone line as an answering machine, you 
may need to change the number of rings. For information, see answer

port (“R-interface”) on an ISDN terminal adapter.
