Conclusion: The wireless Canon MX420 inkjet is a well-rounded printer, scanner, copier and fax machine with only a few problems. We feel that the problems it does have are small enough to be worked-around, such as the fact that the various printouts and photos would have red lines through the copy. Since this only happened a few times, the pros far outweigh the worst of the cons.
Pros: Great high quality photo printing in all sizes, Slightly lower overall energy consumption, Professional grade text printouts, No misfeeds, misalignments, or jams, Wireless capability
Cons: Red lines in the printouts were seen sparingly throughout our tests, Text draft mode scans appeared crooked, Printing in draft mode is no speedier than printing in default mode
Excerpt: The MX420 is one of three new models added to Canon's huge range of inkjet PIXMA multifunction peripherals (MFPs). It's a highly-specified device aimed at the home office, so it can print, scan, copy and fax, and comes with a 30-sheet automatic document feeder (ADF) for multi-page jobs. It can connect to a home network via a wired Ethernet port or by 802.11 b/g/n wireless, or you can hook up a single PC using the USB port.
