• Make sure you connected the HP PSC from the port labeled 
“1-LINE” to your telephone wall jack using the phone cord 
supplied in the box with your HP PSC.* This special 2-wire cord is 
different from the more common 4-wire cords you might already 
have in your office. Check the end of the cord and compare it to 
the two types of cords shown below:
If you used the 4-wire cord, disconnect it, find the supplied 2-wire 
cord, and then connect the 2-wire cord to the HP PSC (at the port 
labeled “1-LINE”). For more information on how to connect this 
cord, refer to fax setup on page 115.
* This possible cause/solution applies only in the countries/regions that 
receive a 2-wire phone cord in the box with the 
HP PSC, including: 
Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Greece, 
India, Indonesia, Ireland, Japan, Korea, Latin America, Malaysia, Mexico, 
Philippines, Poland, Portugal, Russia, Saudi Arabia, Singapore, Spain, 
Taiwan, Thailand, USA, Venezuela, and Vietnam.
Note: If the 2-wire cord is not long enough and you need to extend 
it, you might want to purchase a telephone cord extension 
connector. Attach the 2-wire cord from the HP PSC to one end of the 
extension connector, and then attach a 4-wire cord from the other 
end of the connector to the telephone wall jack.
• Make sure you have correctly connected the HP PSC to the 
telephone wall jack, and correctly connected any additional 
equipment and services that share the phone line with your 
HP PSC. 
Use the 1-LINE port on the back of the HP PSC to connect to the 
wall jack, and use the 2-EXT port to connect any other equipment, 
such as a PC modem or an answering machine. For more 
information and connection diagrams, see fax setup on page 115.
