| 43762 | 2002-04-14 07:13:00 | Following the PC World review I've ordered a 670U. Have found today that a new D646U is on the market. I need some clarification on -bit ratings. The 670U is stated as 48 bit.the spec from the Canon website says scan colour 16 bit input/8 out 'for each colour' and 16/8 for grayscale. The 646U is stated as 48 in /24 out on the promo page but 42 bit input/24 output colour and 14 in/8 out in the spec. 646 is USB 1.1 while the 670 is USB. The 646 is $229 while DSE is offering the 670 for $253. 464 has AC power; 670 USB power. Is the better buy the higher bit rate ? |

The 670 uses ContactImageSensors via leds to see the image and dont do a bad job.The unit is light and compact and requires no additional power sources other than a USB port and requires win98 or better. The 646 is a bigger beast using a flurosecent light source and CCDs.They to do a good job and are faster but there size and the fact a powerpack is required can be an issue especially if you have a Laptop. Either way they are both good but if portability is whats needed then the 670U is the way to go.But if it gonna sit under the bench most of its life then the D646 will do and save you a dollar or 50 ==Orac== |
