HP OJ4650 Betriebsanweisung

Many telephone companies provide their customers with digital phone services, such as the following:

●

DSL: A Digital subscriber line (DSL) service through your telephone company. (DSL might be called ADSL

in your country/region.)

●

PBX: A private branch exchange (PBX) phone system.

●

ISDN: An integrated services digital network (ISDN) system.

●

VoIP: A low-cost phone service that allows you to send and receive faxes with your printer by using the

Internet. This method is called Fax on Voice over Internet Protocol (VoIP).
For more information, see

HP printers are designed specifically for use with traditional analog phone services. If you are in a digital

phone environment (such as DSL/ADSL, PBX, or ISDN), you might need to use digital-to-analog filters or

converters when setting up the printer for faxing.

HP does not guarantee that the printer will be compatible with all digital service lines or providers, in

all digital environments, or with all digital-to-analog converters. It is always recommended that you discuss

with the telephone company directly for the correct setup options based on their line services provided.

You might be able to subscribe to a low cost phone service that allows you to send and receive faxes with

your printer by using the Internet. This method is called Fax on Voice over Internet Protocol (VoIP).
The following are indications you probably use a VoIP service.

●

Dial a special access code along with the fax number.

●

Have an IP converter box that connects to the Internet and provides analog phone ports for the fax

connection.

You can only send and receive faxes by connecting a phone cord to the port labeled "1-LINE" on the

printer. This means that your connection to the Internet must be done either through a converter box (which

supplies regular analog phone jacks for fax connections) or your telephone company.

Support for traditional fax transmission over any Internet protocol telephone systems are often

limited. If you experience problems faxing, try using a slower fax speed or disabling the fax error-correction

mode (ECM). However, if you turn off ECM, you cannot send and receive color faxes.
For more information about changing the fax speed, see 

. For more information

about using ECM, see 

If you have questions about Internet faxing, contact your Internet faxing services support department or your

local service provider for further assistance.

You can set up the printer to print error reports and confirmation reports automatically for each fax you send

and receive. You can also manually print system reports as required; these reports provide useful system

information about the printer.
By default, the printer is set to print a report only if there is a problem sending or receiving a fax.

A confirmation message that indicates whether a fax was successfully sent appears briefly on the control

panel display after each transaction.
