How do i change the phone number on an hp

While "Speed Dialing" or "Speed Dial" is listed in its fax specifications on some sites, it appears to be a mislabeled categorization of its group fax feature as HP's manual makes no other mention of it--save to say, the "fax to multiple numbers" (or multiple recipients) feature. There does not appear to be a speed dial list, but there is a phone book feature for adding contacts (individual numbers) & groups. (The following is detailed in a more explanatory way on pages 65-66 of the user's manual (http://support.hp.com/us-en/product/HP-Officejet-5740-e-All-in-One-Printer-series/6617253/model/6617254/manuals?cc=us&lang=en).

1. From the printer control display, touch Fax.
2. Touch Send Now.
3. Touch the telephone symbol to access its phone book feature.
4. Touch the person symbol for a phone book contact; or touch the multiple person symbol for a group of phone book contacts.
(Note: Contacts should be established before any of these could be added to any group.)
5. Touch + (plus sign) to add a contact/group; or touch the gear symbol (edit) to edit/delete a contact/group.
6. Touch Name.
7. Changes to contacts/groups:
•Adding a contact/group: type the name, & then touch Done.
••Adding a fax number to a contact: Touch Fax Number, enter this contact's fax number, & touch "Create".
••Adding a contact to a group: Touch Number of Members, select all of the contacts to add to this group from this printer's phone book, & touch Select followed by touching "Create".

•Editing: Select the contact/group name, & then touch Done. Then...
••Editing a Contact: touch Fax Number, enter the fax number, & touch Done.
••Editing a Group: touch Number of Members & deselect the contacts to remove from this group or touch + (plus sign) to add contacts to this group. Then touch Done.

•Deleting a contact/group: Select the name, & then touch Delete followed by touching Yes.

The caller ID phone having the tip & ring detection circuit to detect the incoming phone number, but in this model doesn't have tip & ring detection circuit to display other phone number but after connecting the other fax it will read the information which was stored like company name & phone number of other one..

I have a newer model, and I don't think it locks to a specific fax number, but try this: (By reseting you will lose any stored numbers.)

Here's a link to the manual: http://h10032.www1.hp.com/ctg/Manual/c00844812.pdf

The default setting for an Officejet 4255 is to answer the phone after 2 rings. You can change this setting to a higher number of rings which will give you time to answer the phone before the fax picks up.

The instructions you need to change the default answer setting can be found on page 47 of the user manual.

Hit setup. Arrow to fax setup (4). Hit ok.
Arrow to fax header, hit ok. Enter name, ok. THAT should bring you to the phone number.

turn off answering mech. count # of rings before fax answers add onemore ring to answering mech. before it answers.

I did a little troubleshooting--in other words looked for the obvious--such as Menu...then kept on until I saw the number (original) out there--then, just plugged in the new one.

Thanks for answering so quickly!

1) Make sure you cave connected the phone lines in correctly and firmly.

2) Do you have DSL? Make sure you have a filter on the line.

3) Check with your phone company to see if the line is up to standard.

Printers over networks are slower and this could be your problem.
