Xerox claims a top speed of 64ppm for the Phaser 6510V/ND, but printing our five-page text document only showed 25ppm. On the longer, 20-page test, however, this rose to 42.9ppm. This is a bit faster than from the Samsung machine, which gave 38.7ppm.
The story repeats with the 20-side duplex document, where the Samsung produced 26.7ppm, but was pipped by the Xerox at 28.6ppm. Both machines took 9s to print a 15 x 10cm photo on A4. The Xerox printed a similar image from its front panel USB socket in 18s.
The quality of prints from the big Phaser is very good. Despite the high-speed, text from the 600dpi print engine is sharp and well formed. Even emboldened headings come through crisp and densely black. Greyscale graphics are also well reproduced, though the range of greys translates some colours to very similar shades.
Our test photo came through a little dark by default, but detail was good and the lightness could be adjusted.
There are three consumables in the machine, an 80,000-page drum, a 150,000-page maintenance kit and toner cartridges in either 13,000-page or 30,000-page capacity. With these high yields, maintenance time should be short and working through the typical online prices gives a page cost of 2.0p, including 0.7p for paper. This is a good price, but still 0.4p higher per page than the Samsung.
If we hadn't recently looked at theSamsung ML-6510ND, we would have been more impressed with the Xerox Phaser 6510V/ND. As it is, although the Xerox printer is marginally faster, it's more expensive to run and in virtually all other respects there's little to choose between them. Since the Samsung machine is around £420 (35 percent) cheaper, it's hard to find a reason for going the Xerox route.
