Summary: It is advertised as a small office machine, but our small office does too much copying (like a newsletter) for it. It slows down after about 35-40 copies (one-sided). The toner is small & doesn't last very long. When copying, it sends out the page upside down so you can't see what you copied without turning it over. WE are looking into finding a new machine & returning this one.
Summary: Please note that this review is based upon my experience with this printer in Mac OS X 10.8. This review will likely not be typical of Windows users, so if you're a Windows user and are looking for a nice MFP, PLEASE don't let my review sway you away from this printer. There are plenty of other reviews here to give you a good idea of what you will experience as concerns the Windows OS.
Summary: This was a Gold Box Deal from Woot on Monday, September 10, 2012. Let me start off by saying the Canon D420 is an attractive machine and appears to be well built. The unit was packaged very well and arrived quickly. I think it may be an older style, the product manual is dated 2008. The trouble for me began with attempting to install the printer/scanner software on my Mac Mini, 2.26 Core 2 Duo running Lion 10.7.4.
Canon support and information is scant for OSX 10.7 Lion

Summary: Printing from the built in Lion Preview hangs preview and textedit when attempting to print. Canon doesn't have a user support area, forum or any info about this huge bug, even with the current drivers. Apparently the previous drivers crashed the entire computer, so the AUG 30, 2011 drivers at least don't do that. The workaround is print thru chrome or adobe reader. and don't print through textedit.
Good printer but don't buy until you price the toner

Summary: After 6 months, we have replaced this printer because of ridiculous toner prices. You have to choose $80 Canon 128 toners or cheap after-market toner. Read the reviews - the Canon 128 gets very limited page output for a VERY expensive cartridge. So, we tried two brands on after-market toners. Both produced unacceptable output. Don't buy this printer without researching the toner cartridge cost and reviews.
