HP OJ 3830 Owner's Manual

●

If you are using either a private branch exchange (PBX) or an integrated services digital network (ISDN)

converter/terminal adapter, make sure the printer 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 printer shares the same phone line with a DSL service, the DSL modem might not be grounded

correctly. If the DSL modem is not grounded correctly, 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.

You might notice static on the phone line again in the future. If the printer 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.

●

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 printer directly to the

telephone wall jack.

●

If you are not using a distinctive ring service, check to make sure that the Distinctive Ring feature on

the printer is set to All Standard Rings. For more information, see 

●

If Auto Answer is set to Off, you need to receive faxes manually; otherwise, the printer cannot receive

the fax. For information on receiving faxes manually, see 

.

●

If you have a voice mail service at the same phone number you use for fax calls, you must receive faxes

manually, not automatically. This means that you must be available to respond in person to incoming

fax calls. Learn more about setting up the printer when you have a voice mail service, 

. For information on receiving faxes manually, see 

●

If you have a computer dial-up modem on the same phone line with the printer, check to make sure that

the software that came with your modem is not set to receive faxes automatically. Modems that are set

up to receive faxes automatically take over the phone line to receive all incoming faxes, which prevents

the printer from receiving fax calls.

●

If you have an answering machine on the same phone line with the printer, you might have one of the

following problems:

◦

Your answering machine might not be set up correctly with the printer.

◦

Your outgoing message might be too long or too loud to allow the printer to detect fax tones, and

the sending fax machine might disconnect.

◦

Your answering machine might not have enough quiet time after your outgoing message to allow

the printer to detect fax tones. This problem is most common with digital answering machines.

The following actions might help solve these problems:
