Conclusion: i have used two Canon multi function devices over many years. The latest, this model, repeat previous experiences by adding a complex and un-intuitive set of software and drivers to support completely mundane and expected tasks like scanning, printing and faxing.
Good build quality, but odd size paper handling can be troublesome

Summary: I have both the 4890dw and the 5950dw. The 4890 is a little weak on build quality, so if you want a good all around multifunction and you will only print on standard letter size or envelopes, I would choose this over the 4890 for about $100 more.
Summary: This item is fast, works well with duplexing, but is not automatic with its scanning vs printing. When the computer asks to scan, I must push buttons the the Canon to get it to go into FAX mode.
Two in a row didn't work (Firmware updates defective and Canon support doesn't have proper escalation procedure)...

Summary: Just days ago I purchased one of these. Upon arrival I installed the drivers to the O/S (Windows 7 64 bit) and firmware update to the printer. Note: All of the updates came directly from Canon's website, so they are the latest and not older updates on the supplied CD that shipped with the unit.
Summary: Speed, at 35 ppm, is what sets this unit apart in a sea of B&W multifunctions with duplex and Wi-Fi connectivity. In real word the speed was more like 25 ppm but the first page is out within 7 seconds - very nice. Real word Duplex speed is 12-15 ppm.
