Printing The Canon imageClass MF642Cdw prints using laser technology, which picks up powdered 'toner' on a roller and fuses it to the paper with heat. It has very good text quality, though not quite as good as the best printers. Text printing speed is typical, 5 pages took 22 seconds, costing 4.5 cents per page. It prints color graphics such as charts and web pages beautifully, in presentation-quality, with no noticeable defects, costing 36.7 cents per page. It has auto-duplex printing to print both on sides of the page. Individual cartridges for each color let you change only the ones that are empty. If any color ink runs out, it stops printing—it can't be set to just use the remaining black ink. If the black ink runs out, it stops printing—it can't be set to just use the remaining color ink. The capacity of the main paper tray is 150 sheets, a typical amount. There's a second single-sheet input tray for full-size paper, in case you just need a printout on letterhead, for instance.
Scanning and Copying This is a multi-function printer. Scanning performance was OK, but had a few noticeable flaws. It has an Automatic Document Feeder (ADF) for easily scanning/copying a stack of pages.
Controls and Display The printer has a color display screen 5-inch diagonal size, touch-input capability, and can be tilted.
Connectivity and Networking It can print documents via USB, USB thumb drive, Ethernet and WiFi. We found it relatively easy to setup the WiFi connection on this printer.
Cost of Ownership and Toner When this page was last updated, the printer's purchase price was about $400, typical for a all-in-one color laser printer. Printing uses up toner and the costs add up over time. This printer uses four (4) cartridges. When the ink runs low, you replace the empty cartridge. The toners we used in testing were the Canon 054H BK, 054H C, 054H M, and 054H Y cartridges—at the time, the prices were $111, $113, $113 and $113 respectively. We estimate each cartridge of toner to last at least 8 years—a very long time—following a typical monthly printing amount of 28 text and 12 graphic pages. After 2 years of typical use, we estimate your total equivalent cost to be $536—typical for a color laser. The estimated yearly cost is $68, which is typical for a color laser type of printer. The theoretical total cost after 5 years is $740. The printer needs a moderate amount of space .
Printer Firmware Firmware is software that exists inside the printer. All models are evaluated using the latest firmware version available at the time of testing.
Software The collection of software accompanying the printer may include: the printer driver, printer applications, electronic user manual and scanning, faxing, and OCR apps. These get installed on your personal computer. All models are evaluated with a PC and the Windows operating system, using the latest version of printer software (driver) and printer support apps available at the time of testing. The software version was 1.20.0.0.
