"After the successful launch of the RX520, a photo-targeted all-in-one
device, Epson has come up with its larger, more capable cousin, the RX640.
As well as being able to print, scan and copy, this machine can upload or
print from memory cards or a PictBridge camera, scan and print
transparencies and negatives, and print to CD or DVD blanks. It also prints
in six colours, compared with the RX520’s four."
