Stay away from Canon Laser MFPs. My experience : Canon Laser MFP (All In One) 4350. Mine went bad within 18 months of usage. I had paid around 16K while buying this device as I wanted one with an ADF (Automatic Document Feeder). The ADF is just there for namesake and its painfully slow. If you really have some bulk photocopying to do, you need to look at Rs. 50K+ devices instead.
Also this model in particular seems a very sloppy build. First, it started giving a "System Error - 225" and hanged completely but this was fixed by simply restarting the device. Then the frequency of this error started increasing. Google search told me that it could be fixed by a firmware upgrade from the official website, but this did not work. Imagine my surprise when on taking it to them, the service center people told me that the scanner lamp was gone and I need to pay 6K + labor charge to get it fixed.
I have 5 printers in my SOHO, all laser. All the others are Canon LBP 2900B and HP 1020s. These smaller devices have much higher workload (200 prints a day) on them and never went bad. This particular printer had about 15 prints and about 2 scans a day, and the scanner lamp was hardly used. Despite it being the most expensive and having the highest rated duty cycle, it was the 1st one to go bad.
Mind you, the whole device was working perfectly after a simple restart (how on earth was that possible with a bad scanner lamp). I even asked the Canon people that if the scanner lamp was bad then at least I should be able to use it as a printer, but apparently its not possible. It feels as if Canon has knowingly inserted this problem into this device which activates like a time bomb immediately after the warranty gets over (which is only 12 months), or maybe they failed to recall a very faulty set of devices with bad quality scanner lamps.
My advice and what I have done: Trash this MFP. Instead buy a brand new Canon 2900 LBP (very good model and saves you from the crappy Canon Scanner lamp) + HP deskjet 1050. (Rs. 6000 + Rs. 3100 = Rs. 9100).
