Scanner
A positive aspect is its speed. It takes just 7 seconds to preview a document, and that's three times faster than the X83. A negative aspect is that, though fast, it does a poor job. The images have too much contrast, the device does not include moiré adjustment, interpolation is poor and the lightest areas come out pale. The PSC 950 is no replacement for a scanner when you need to touch up and reproduce photos.
Photocopier
While the integrated scanner does a poor job, the photocopies are of fairly good quality. Go for the color reproductions: the characters are rendered more finely than in monochrome.
Note that the PSC 950 is the only multifunction device which can do satisfactory photo reproduction in monochrome mode.
