HP 7200 HP All-in-One is having problems sending a manual fax

Troubleshooting information

Chapter 16

●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, see Use 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. The DSL filter removes the digital signal and allows your HP All-in-One to communicate properly with the phone line. Obtain a DSL filter from your DSL provider. If you already have a DSL filter, make sure it is connected correctly. For information, see Case B: Set up your HP All-in-One with DSL.

●Make sure your HP All-in-One is not connected to a telephone wall jack that is set up for digital phones. To check if your phone line is digital, connect a regular analog phone to the line and listen for a dial tone. If you do not hear a normal sounding dial tone, it might be a phone line set up for digital phones.

●If you are using either a private branch exchange (PBX) or an integrated services digital network (ISDN) converter/terminal adapter, make sure the HP All-in-One is connected to the port that is designated for fax and phone use. Also, make sure that the terminal adapter is set to the correct switch type for your country/region, if possible.

Note that some ISDN systems allow you to configure the ports for specific phone equipment. For example, you might have assigned one port for telephone and Group 3 fax and another port for multiple purposes. If you continue to have problems when connected to the fax/phone port, try using the port designated for multiple purposes; it might be labeled "multi-combi" or something similar. For information on setting up your HP All-in-One with a PBX phone system or ISDN line, see Fax setup.

●If your HP All-in-One 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 your HP All-in-One stops sending and receiving faxes, repeat this process.

If the phone line is still noisy or for more information on turning your DSL modem off, contact your DSL provider for support. You can also contact your telephone company.

●If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord connector that plugs into a telephone wall jack.) Try removing the splitter and connecting the HP All-in-One directly to the telephone wall jack.
