Canon rates the i-SENSYS LBP7660Cdn at 20ppm for both black and colour print. We got somewhere near this with the longer, 20-page, black text print, which returned 15.2ppm, though the more typical 5-page test only managed 9.1ppm. The black text and colour graphics print it slightly better than this at 9.4ppm, but for day-to-day tasks you should take the headline figure with a substantial shower of salt.
The printer offers duplex as standard, which is still something of a rarity among medium-priced colour laser printers. It handles the task very straightforwardly, by feeding each sheet out of the exit slot and then rolling back in to print the second side. It managed 8.8 sides per minute on our 20-side test document, which is a reasonable result, though perhaps not fast enough to make duplex the default setting on the machine.
Although it only appears to differ by a couple of decibels from other machines, subjectively this printer feels a lot quieter than many and can be comfortably used on a desk beside you. Admittedly, unless you have a big desk, there won’t be much room left for keyboard and mouse, or even pen and paper, though.
Canon is well-known for the quality laser print in both its own and in HP printers, for whom it makes many of the engines. Here it produces crisp, dense print with 600dpi resolution, high enough to produce smooth curves and diagonals.
Colour graphics are dense and completely un-banded, offering bright colours, though with some haloing around text over orange fills. Darker blues and greens are also printed slightly oversaturated, so text can become lost. Our test photo suffered a little from the limited colour gamut of the printer, though against this it managed to retain some shadow detail which rival colour lasers lose.
The four combined drum and toner cartridges are only available in a single yield, of 2,900 pages for each colour and 3,400 for black. These are reasonable capacities, even in a fairly busy office and give ISO page costs of 3.4p for black and 12.4p colour, each including 0.7p paper cost. These costs lie slightly above those of some mid-range colour lasers, but you can add in lower than average maintenance costs, because of the easy-access design of the cartridge tray.
This is a good, down to earth office colour laser, producing good quality print at reasonable cost. It’s not quite as fast as Canon would have you think, but you won’t be waiting long for most print jobs. Duplex colour print is unusual in this class of machine and is a cost-cutting bonus.
