been running one of these now for about 6 months with my windows 7 64 bit system and not had any issues. The fact you can get a black and colour toner cartridge for less than £15 means that this little baby is extremely cheap to run. In the past inks have dried up on me as I didnt use them enough (due to expense, had lexmark and epson all in ones before) the cartridges now arent in the device long enough to dry up! Thoroughly recommend it for home use!
