The Canon i-SENSYS MF4450 is rated at 24ppm and, although both our five-page text and text and graphics documents returned 15ppm, the longer, 20-page test produced 20.3ppm, which is not far off the manufacturer’s claim. This is quick for a printer in this class.
At least part of the speed is due to the fast start-up the machine manages. We’re a little cynical of claims to produce quick first prints from laser printers, when they also have low-power sleep modes. In this case, though, there’s little argument, as the printer starts up from sleep and produces its first page in around seven seconds.
This increases the measured speed on our tests quite considerably and it applies equally to copies from flatbed and ADF. A single page from the flatbed took 10 seconds and a five-page document ran through the ADF in 22 seconds. A 15 x 10cm photo on an A4 sheet came through in 9 seconds.
Print quality is up to Canon’s usual standard, with very clean text from the 600dpi head which, with enhancement, gives 1200 x 600dpi. Graphics are also well reproduced with smooth greys, though there’s not much variation between mid-grey levels, so colours with similar greyscales may be hard to distinguish. Reversed text is well formed, with no missing descenders.
Copies are also good, though copies of fills are poor, with a lot of blotches and some loss of density in lighter shades. Canon is not alone in this shortcoming, though and its photo reproduction is better than most, with smooth grey gradations, though a little loss of detail in dark greys.
The printer uses a single, integrated drum and toner cartridge, available in one capacity only. Using this 2,100 page consumable gives a cost per page of 3.2p, which is better than the 3.5p of the similarly priced Samsung SCX-3405FW
The Canon i-SENSYS MF4450 is a good SOHO laser multifunction, which is surprisingly quick, prints well – though greyscale copies are a bit ropey – and is relatively cheap to run. Fax, copy and scan are all well supported, but the machine can’t print duplex and doesn’t have a wireless connection. If you can live without these facilities, there’s no other reason to go elsewhere.
