HP 7640 Faxing with a calling card

[Tina704]

Rec'd a HP 7640 All-in-One Printer as a gift.  I do not have long distance on my local landline phone, so I use a calling card when sending a fax.   The problem I'm having is I use the numeric keypad to enter my calling card number - pin - and number I'm calling with pauses in the appropriate places.  Everything is fine until I get the recording after dailing all the necessary numbers, when it tells me how many minutes I have left, when they expire, yada, yada, while the fax just beeps.  The fax never sends and I get the message Recepient Busy.  Is there any work around?  Or enabling the numeric keypad to reappear after I've started the fax for more input?  

Previously I had a Brother MFC and never had a problem sending faxes because  the numeric keypad was on the front of the printer . . so I could wait for prompts.  When I was done dialing everything, THEN I would hit send.

@Tina704,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that you are unable to send a fax using calling cards from your HP ENVY 7640 e-All-in-One Printer.

This issue could occur if the fax settings are not correct.

Let's go through a few steps to resolve this issue.

And here's the step by step guide for you in the link: http://hp.care/2lQbKaI

If the receiving fax machine is busy then you can send a fax from Printer memory.

You can scan a black-and-white fax into memory and then send the fax from memory. This feature is useful if the fax number you are trying to reach is busy or temporarily unavailable. The printer scans the originals into memory and sends them once it is able to connect to the receiving fax machine. After the printer scans the pages into memory, you can immediately remove the originals from the document feeder tray or scanner glass.

NOTE: You can only send a black-and-white fax from memory

To send a fax from memory:

1. Ensure that Scan and Fax Method is turned on.

a. From the printer control panel display, touch Setup.

b. Touch Fax Setup, and then touch Preferences.

c. Set Scan and Fax Method to on.

2. Load the original print side up into the document feeder, or load the original print side down on the right front corner of the scanner glass.

3. From the printer control panel display, touch Fax.

4. Touch Send Now.

5. Enter the fax number by using the keypad, touch (Phone book) to select a phone book contact or to select a previously dialed or received number.

6. Touch Black. The printer sends the fax when the receiving fax machine is available.

You can send a fax to multiple recipients by creating a group phone book contact made up of two or more individual recipients.

To send a fax to multiple recipients using group phone book:

1. Load the original print side up into the document feeder, or load the original print side down on the right-front corner of the scanner glass.

2. From the printer control panel display, touch Fax.

3. Touch Send Now.

4. Touch (Phone book).

5. Touch (Group Phone Book Contact).

6. Touch the name of the group phone book contact.

7. Touch Send Fax. If the printer detects an original loaded in the document feeder, it sends the document to each number in the Group Phone Book contact.

TIP: If the recipient reports issues with the quality of the fax, try changing the resolution or contrast of your fax.

Let me know how this works.
 

You have a good day ahead.
