Question about HP 640 Inkjet Fax Machine

HP 640 Fax series not printing

I haven't used it for about the last 4 months, but when someone tried to fax me, the page came out blank. The machine sounded like it was printing but there was nothing printed. I ran a test but that also came out blank. The ink level is 7/8.

If it is a color printer, try printing just grayscale or black& white.  It is is already set to print just b/w, try printing in color.  Basically you may be out of ink.  Run the printer utility to clean the heads and see if anything changes.  A new set of cartridges should fix the problem, I believe.
Hope this helps...

I need to reprint the last inoming fax. HELP!!!


Printing a Fax in Memory If you have Fax Storage ON for remote retrieval, you can still print a fax in the memory when you are at your machine: 1 Press Menu/Set, 8, 4. 2 Press Fax Start. 3 Press Stop/Exit. (See Turning On Fax Storage, page R-2.) Polling For details about the Polling feature, call our Brother fax-back system 1-800-521-2846 (in USA), 1-800-681-9838 (in Canada) and request at the Index. (See Features That Are Not in the Manual, page 6-6 for details.) Polling is the process of retrieving faxes from another fax machine. You can use your fax machine to "poll" other machines, or you can have someone poll your machine. All parties involved in polling need to set up their fax machines to accommodate polling. When someone polls your machine to receive a fax, they pay for the call; if you poll someone's fax machine to receive a fax, you pay for the call. (See Canceling a Scheduled Job, page 6-5.) Some fax machines do not respond to the Polling feature.

The recipient may have a DSL phone line, or receiving to a fax server that blocks your area code.
