OKI 5600n LED Printer Review - OKI 5600n LED Printer Review


Print has a notable gloss finish, which is a matter of personal taste, but black text looks very clean and well-defined at the printer’s default resolution of 600dpi. Colour graphics, as you might see in a PowerPoint presentation, print well with no noticeable banding and good reproduction of vivid colours.

When it comes to photo prints, you can take the resolution up to 1200dpi by 600dpi and the definition of the images is then pretty good, though with some slight banding apparent in solid areas, like sky. What isn’t so good is the colour rendition, where colours by default are oversaturated. OKI provides a palette tuning utility, however, which can improve things with a bit of tweaking.

There are a lot of different consumables in the C5600n. Toner cartridges for each of the four colours clip on top of their separate image drums. The black toner lasts for 6,000 pages, while the colour ones should go for 2,000. The image drums themselves last for 20,000 pages, then there’s a transfer belt and a fuser unit, each of which should last 60,000 pages.

To add to the complexity of working out a page cost, there are a couple of special deals available on consumables, which don’t appear to be time-limited. The rainbow toner pack reduces the cost of the four toners from £227 to £175 when you buy them all at once and the image drums value pack cuts the price of four image drums from £122 to £116. We used the price of these multipacks in calculating the page cost, as this gives the lowest cost, overall.

Surprisingly, we saw a lower 5 per cent black page cost then OKI quotes. We reckon that even with 0.4p for a sheet of paper and VAT on top, a page should cost around 1.5p, when OKI quotes it at 2.2p. Colour costings go the other way, as our calculated figure is 8.5p, while the company quotes 7.04p. Both black and colour figures are good for this class of machine, though you will have to keep an eye on all these different consumables.


This is a good small office or small workgroup colour laser, which gives quality prints quickly – particularly quickly when you look at its colour output. It’s also comparatively cheap to run and is a good choice for general office duties.
