THIS MACHINE RECEIVES FAXES QUICKLY.IT HASN'T FAILED YET.THE TONER CARTRIDGE HAS OUT RUN THE 4 HP CARTRIDGES IN OUR OFFICE JET 6300. IT GETS VERY HEAVY USE 1 OR 2 HP CARTRIDGES A WEEK. PRINT QUALITY IS VERY GOOD. I RATE THIS FAX BETTER THAN ITS OFFICE JET COUNTERPARTS REGARDING DURABILITY AND ECONOMY.R D LOUVAR
