Can send but not receive faxes - HP Officejet Pro 8500 Wireless All-In-One InkJet Printer

If the person who is sending the fax cant send in color, then you would not be able to receive the fax in color. Just make sure you choice the option to received the fax in color. Ask someone to send you a fax in color and just received in color.

"cannot send or receive faxes to one particular number, but is able to send and receive faxes with other numbers"

If your machine can receive a fax transmission from one number, it will receive from all numbers.

If your machine can send to all but not to one particular number, please check that there is a fax machine there to receive it.

You can try to send manually and listen for beeps from the other fax -if one is present- then push the START button to initiate transmission.
If their machine is in working order, the transmission should start. (After the initial 'handshake' of course.)
