No outlandish speed claims are made for the i-SENSYS MF8050Cn, with Canon quoting 12ppm for black print and 8ppm for colour. Even so, we found the figures a little out of reach. Our five-page black text print returned 5.77ppm and although we saw 9.52ppm for the 20-page test, it’s still some way short of the target figure.
Our colour test produced a speed of 4.84ppm, little more than half the rated figure. Subjectively, the machine seems slow and when copying a five-page text document from the ADF, it was noticeable that the scanning finished before the first page was out of the printer.
Canon also claims Quick First-Print as a key feature of the machine, but it was always 20 seconds or more from clicking Print to the first sheet starting to move through the print engine. There are plenty of colour lasers that take half that time.
The quality of the print is as good as we've come to expect from Canon, though normal black print is a little lighter than from some of its rivals. Black text and colour graphics show the high quality of colour fills and although there's some texturing of areas of fill, colours are good and solid areas come out well. There's a little haloing of black text over coloured backgrounds.
A colour copy produced very little degradation from the original and colour tones were well reproduced at very close to their originals shades. Our photographic print looked more natural than many, with much less of the characteristic over-saturation many lasers produce. The default 600dpi resolution of the print engine is quite noticeable in dither patterns, however.
The only consumables are the four drum and toner cartridges, which cost just under £50 each and are good for 2,300 pages of black and 1,500 pages of each colour, at ISO coverage levels. This produces page costs of 2.91p for black and 11.88p for colour. These costs are about average for a colour laser device of this type, though we have seen lower costs for colour pages.
This is a reasonable colour laser multifunction device from Canon, though the lack of a walk-up print facility and the paltry capacity of the main feed tray are odd design aberrations from a company which normally gets these things right. Even its inkjet all-in-ones have two, 150-sheet paper trays as standard.
