HP OfficeJet Pro 7740 - Manual (Page 93)

NOTE: You need to purchase a parallel splitter. A parallel splitter has one RJ-11 port on the front and two
RJ-11 ports on the back. Do not use a 2–line phone splitter, a serial splitter, or a parallel splitter which has two
RJ-11 ports on the front and a plug on the back.
Figure 5-10 Example of a parallel splitter
To set up the printer with a computer DSL/ADSL modem
1. Obtain a DSL filter from your DSL provider.
NOTE: Phones in other parts of the home/office sharing the same phone number with DSL service
need to be connected to additional DSL filters to avoid noise when making voice calls.
2. Using the phone cord supplied in the box with the printers, connect one end to the DSL filter, then
connect the other end to the port labeled 1-LINE on the back of the printer.
NOTE: You might need to connect the supplied phone cord to the adapter provided for your country/
region.
If you do not use the supplied cord to connect from the DSL filter to the printer, you might not be able to
fax successfully. This special phone cord is different from phone cords you might already have in your
home or office.
3. If you have a parallel-type phone system, remove the white plug from the port labeled 2-EXT on the
back of the printer, and then connect a phone to this port.
4. Connect the DSL filter to the parallel splitter.
5. Connect the DSL modem to the parallel splitter.
6. Connect the parallel splitter to the wall jack.
7. Run a fax test.
When the phone rings, the printer automatically answers after the number of rings you set in the Rings to
Answer setting. The printer begins emitting fax reception tones to the sending fax machine and receives the
fax.
If you encounter problems setting up the printer with optional equipment, contact your local service provider
or vendor for further assistance.
Case I: Shared voice/fax line with answering machine
If you receive both voice calls and fax calls at the same phone number, and you also have an answering
machine that answers voice calls at this phone number, set up the printer as described in this section.
