Canon rates the PIXMA MX435 at 9.7ppm for black and 5.5ppm for colour and in our tests we got somewhere near the black print speed, recording 7.9ppm on the 5-page print and 8.1ppm on the 20-page test.
Colour print didn't get anywhere near the stated figure, though, as the machine kept pausing (for just under 15s) for all pages but the first. We assumed this was drying time for the dye-based colour inks, though it's not a problem we've hit before with Canon printers. We repeated the test and got consistent results, so can only state a speed of 1.8ppm for colour print, which is very slow.
Copy times of 30s for a single colour page and 1:09 for five-pages from the ADF aren't spectacular, either - when compared with the PIXMA MX420, for example, which took 22s and 58s respectively for the same tests. Similar differences came through when we printed 15 x 10cm photos, which took 53s in normal print mode and 1:38 at highest quality on the PIXMA MX435.
The print samples came through well, with crisp, clean black text and unblemished, if slightly pallid, colours on plain paper. Draft print mode is noticeably paler than normal mode and saves very little print time. Photo prints, as always, are among the best we see, with cleanly defined detail in bright and dark areas of images.
The two cartridges are available in standard and high yield versions, with the higher yield variants offering 600 pages of black and 400 pages of colour. You may lose some economy by not having separate colour cartridges, but this will depend on the balance of the cyan, magenta and yellow inks in the colour pages you print. We calculate costs at 3.7p for an ISO black page and 7.8p for ISO colour. Both costs are pretty typical for a machine in this price range.
An all-in-one with ADF, fax and the ability to print and scan via a front panel USB port would normally set you back £100 or more, so the Canon PIXMA MX435 looks like something of a bargain. However, extended colour print times and an awkward paper tray configuration count against this, so it doesn't quite have the feature set and performance of others in the range.
