Silent mode You can turn the sounds of the HP Fax (including ringing) on and off using the control panel button. You can also set all sounds to turn off on a daily schedule; for example, turn all the sounds off between 8 pm and 8 am. 1. Press Menu repeatedly until BASIC FAX appears and press OK. 2. Silent Mode will display. Press OK. 3. Select On-Daily and press OK. From: 00h To: 23h will display. 4. Enter a start time and an end time and press OK.

SOURCE: hp 640 cant send or receive fax(NO ANSWER FROM REMOTE FAX

Since the fax machine is about 4 weeks old, why not give it back to HP? Warranty still covers it.

Face up or down on hp 640 faxes


Load the documents face down in the document feeder. (Print side towards the fax machine.)

HP offers a lot of support for their products. The User Manual for the HP 640 is available here: http://h10032.www1.hp.com/ctg/Manual/c01094202.pdf .

I hope this helps.

Can I set the Hp inkjet as a printer


No you can't. The 640 is a fax machine only. It doesn't have any way to connect to a computer, just to the telephone line. HP's information about this machine is here.

How do you turn off the ringer


On printer control panel, select setup, then select #4 (basic fax setup), then #6 (ring & beep volume). Select OK, then press either the left or right arrow until "OFF" appears - then press OK. This will turn off the ringer for the fax machine and will also silence the keypad tones.
