Problem
The HP Fax is having problems sending and receiving faxes
Possible solution
extension phone is off the hook, or if you are using a computer
Make sure the HP Fax is plugged in. Look at the display on the HP Fax. If the display is blank the HP Fax is unplugged. Make sure the power cord is firmly connected to the HP Fax and plugged into a power outlet.
After plugging in the power cord, HP recommends you wait five minutes before sending or receiving a fax. The HP Fax cannot send or receive faxes while it is initializing after being plugged in.
•Check to see if another process has caused an error. Check the display for an error message providing information about the problem and how to solve it. If there is an error, the HP Fax will not send or receive a fax until the error condition is resolved.
•The phone line connection might be noisy. Phone lines with poor sound quality (noise) can cause faxing problems. Check the sound quality of the phone line by plugging a phone into the telephone wall jack and listening for static or other noise. If you hear noise, turn Error Correction Mode (ECM) off and try faxing again. For information about changing ECM, see Send a fax in Error Correction Mode. If the problem persists, contact your telephone company.
•If you are using a digital subscriber line (DSL) service, make sure that you have a DSL filter connected or you will not be able to fax successfully.
•If you are using either a private branch exchange (PBX) or an integrated services digital network (ISDN) converter/terminal adapter, make sure the HP Fax is connected to the correct port and the terminal adapter is set to the correct switch type for your country/region, if possible.
•If the HP Fax shares the same phone line with a DSL service, the DSL modem might not be properly grounded. If the DSL modem is not properly grounded, it can create noise on the phone line. Phone lines with poor sound quality (noise) can cause faxing problems. You can check the sound quality of the phone line by plugging a phone into the telephone wall jack and listening for static or other noise. If you hear noise, turn off your DSL modem and completely remove power for at least 15 minutes. Turn the DSL modem back on and listen to the dial tone again.
NOTE: You might notice static on the phone line again in the future. If the HP Fax stops sending and receiving faxes, repeat this process.
If the phone line is still noisy, contact your telephone company. For information on turning your DSL modem off, contact your DSL provider for support.
