Lexmark claims a speed of 33ppm for the C736dn, printing black or colour. As usual, these speeds are derived without considering processing time or fuser warm-up, but in this case the printer has an instant-on fuser, so starts printing almost immediately. Even so, we saw a maximum speed of 25ppm on our 20-page black text document. This is pretty quick, but speeds dropped to around 16ppm for five-page black text and text and colour graphics jobs.
The printer has an automatic duplexer fitted as standard and the printer doesn't take as big a hit when printing duplex as many of its rivals. This may have something to do with the unusual feed regime, where it takes in pages two at a time, printing the first sides of each, before turning them and printing the reverse sides. A 20-side, black text document ran at 18spm, fast enough for the machine to be set to print duplex by default, with consequent savings in paper costs.
Print quality for black text is excellent, with clean and sharp characters right down to small print sizes and no signs of toner spatter to fuzz things up. Colour output is vivid, though with some slight haloing around black text over colour. Although the colours were a little bright in our photo test print, the machine managed to reproduce shadow detail better than most.
Although toner, photoconductor drums and the waste toner bottle have different service intervals, making maintenance tricky, they each have relatively long service lives.
If you use the high-capacity toner, which makes sense economically, you only need to refresh black and colour every 12,000 and 10,000 pages, respectively (though 8,000 and 6,000 page units are supplied in the box). Drums last 20,000 pages, as does the waste bottle, so a regular maintenance schedule shouldn't be too onerous.
Using typical internet prices for consumables gives an ISO black cost per page of 1.15p, with 8.42p for ISO colour. Both these figures are very reasonable for this class of machine.
Overall, this is a success for Lexmark and we're happy to recommend it.
Verdict
This is a well-designed colour laser printer for medium and large workgroups. It's fast, produces good quality text and colour graphics and includes modern facilities, such as walk-up printing from USB drives. It's particularly strong on paper handling, though only from the input end and running costs are competitive.
