Re: Modem

If you are in the US the part number is C6735-60001 as listed at HP's Partsurfer site here. For information on part numbers in other countries start at HP's partsurfer site here.

A Google search for C6735-60001 turns up many suppliers, the best price I saw was here. (I have no experience or knowledge of these guys other than what I see in Google....)

Connecting my HP Officejet 4315v All-in-One Printer.Fax.Scanner.Copier with a phone modem in order to use the fax machine

The power cable goes in the socket on the far left. The phone line goes into the port named 1-LINE and runs to the wall. 2-EXT is for you to connect you phone or fax machine if you so wish.

If it is your first time installing the printer I would take a moment to go through the setup as mentioned in the manual here. It seem the USB port should be connected at a specific point during installation.

Hope this helps.

I have a Lexmark P6250 I was told it was an all in one..but I can not see where to hook the telephone cable to fax.

The Lexmark P6250 is an "all-in-one" Printer/Scanner/Copier, but does not include hard-line fax capability.

Unfortunately, there came a time when the manufacturers began referring to any printer/scanner/copier as an "all-in-one" whether it included direct faxing or not. Many of them do not, which makes for a very confusing purchase!

The user's guide (which can be found at gives a basic overview of how to fax using their included software, but in order to do so, you will need to have a dial-up fax modem in your computer, or some kind of internet fax service.

Hope this is helpful!

HP 6310 Cannot send or receive faxes message at startup. Tried another phone line with same result.

This is a result of a fax modem fialure, Common in Hp's what happends is the all in one was plugged into a nakid phone line without a surge surpressor or what not and basically got zapped, other causes could be the modem just not functioning.

Point in case your going to need to have this repaired there is NO reset albeit Magic wand that a tech shakes at it to make it work.

Let me know your comments if you wish, please do not forget to rate. Thanks

My printer say off the hook when you try to send a fax and can not recieve either

Unplug power and pull the modem out then re-install. It is held in by plastic clips.

Modem is probably bad.

Not receiving faxes

Check settings auto-answer on....rings to answer set at 1 or 2...make sure receive faxes to memory is not turned on...what you could do is restore all settings to factory defaults. This can be found in the menus. If none of this works...replace the fax modem.

Replacing the fax modem?

Modem is part of the main board. Have to replace the whole board. We have used boards.
