Summary: This is a great machine except for two things. The toner out light will come on almost all the time unless it is a brand new cartridge. For example you put a new catridge in and one week later it says "out of toner change toner" when in fact there is plenty of toner. Sometimes you will have to shake the cartridge but there is weeks worth of toner still in the cartrige. The menu is also non-intuitive.
Summary: The good: This is an amazing work horse of a printer. Toner cart is about $80 for 2000 copies and if I take the cart out and shake it, I can go 50 pages past the warning. The doc feeder works reliably and the thing is fast. Prints are crisp and perfect absolutely every time. The less good: Doesn't actually scan if used on a mac BTW, Vuescan DOES manage to scan on the mac. hmmmm ). Canon's advertising makes no effort to inform you of this; it is sold as "mac compatible.
Summary: My husband and I have owned this printer for a year and a half now, and we had no problems with it, until I replaced my laptop to one that runs on a 64-bit Vista operating system. The CD driver that came with it when we purchased the printer (for $169.99 off of Amazon) does not support this (very popular) platform. We searched on Canon's website and all over the Internet to download a driver that would make my new laptop have the ability to print on here...to no avail.
Summary: The Canon 4150 was to be a backup for a Canon 8180c printer. Upon arrival, the 4150 would not duplex, Aweek later the 4150 printer failed. I did pay for a 1 year sq-trade warrenty. The Canon 8180c failed with the same problem. i Have a 2 year sq-trade warrenty on this one. If you buy a used printer, please get a warrenty.
Summary: I bought the Canon MF4150 from a local Office Max- it was a floor model. I bought it anyway because I knew it was a good laser printer and I couldn't beat the price. It was a floor model and I knew it might have some wear on its exterior and maybe a decent amount of toner life in it. What I didn't know was that Canon uses what they call a "starter" toner cartridge that runs out a heck of a lot faster than a regular toner cartridge.
Summary: I bought this printer to replace an aging HP inkjet all-in-one. Like many others I was tired of buying expensive ink cartridges. Since I was very pleased with my Canon Pixma ip6000D photo printer, I thought I'd try this multi-function laser device. I work from home in a mixed environment... 2 Macs and 2 Windows boxes. Canon advertised compatibility with both (granted mac's can't scan).
Summary: This could've been a great printer, but Canon really dropped the ball with Mac OS X support. Most of the functionality of the device IS NOT available on Mac OS X. Duplex printing is NOT available. Scanning is NOT available. What's the point of selling a multi-function printer as Mac compatible if the multi-functions are not supported?
