Lexmark's quoted speeds for the X7675 are very similar to the X4975ve's, which is what you would expect, considering both use the same print engine. For some reason, though, the draft black print speed of this machine is rated 2ppm higher than the other, at 32ppm. In normal print mode it's rated at 13ppm and the colour print speeds are 27ppm draft and 5ppm normal.
As usual, the specifications bear little relation to what we saw in our tests and our five-page black text print took 1:25, a real-world normal speed of 3.5ppm. On the 20-page document, where the 37 seconds of processing time has less effect on the overall result, the speed rose to 5.26ppm, but this is still less than half the specified figure.
Duplex comes as standard and Lexmark all-in-ones do rather better than their Canon and HP rivals at duplexing, as there's a much shorter pause between printing first and second sides. Our 20-page document printed duplex in 4:41, a speed of 4.27spm.
There was a surprising difference between the print speeds for 15 x 10cm photos, depending on source. Printing from a PC took 2:16, but when we went straight from a PictBridge camera to the X7675 it took even longer at 2:32. The best speed, though, came by printing from an SD card, which took just 1:12. This is a reasonable speed, while the others are pretty poor.
The print quality from this machine isn't a patch on its stablemate's. While straight text print isn't too bad, we did see quite a bit of shadowing, where there is some ink smudging due to the heads touching the paper. This has the effect of making some text look bold, when it isn't.
As we've already said, the machine uses the same print engine as the X4975ve, which gave noticeably better print, so we're prepared to believe this smudging effect is particular to our review sample.
Colour graphics are smooth and bright and a colour photocopy does better than many in reproducing the original colours. Our five-page text copy from the ADF, however, showed worse smudging and emboldening than the original and was very blurred.
Our photo print from a PC was also poor, with colours much too dark and virtually all detail in shadowed areas lost. We can't really recommend the print quality from this machine against any of its rivals.
Running costs using the two high-yield cartridges come out at 4.8p per page for black and 8.76p for colour, using ISO yield figures. Both of these are reasonable for a machine at this price, though the black print price is considerably higher than from even a budget laser printer.
If we'd seen the same kind of results from this machine as we saw from its more expensive stablemate, it would have been hard to understand why the other machine was needed. The X7675 should be better value, but the print quality here is much worse and print speeds vary considerably, particularly when printing photos. Unless this is an aberrant sample, this machine can't be recommended.
