Question about HP 640 Inkjet Fax Machine
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...
