Hmmm,
I have thought about this, but I am not convinced.
Take faxing. The only thing that shares with the "printer" is the printing of the fax I cannot envision a problem there. On the sending side, no intersection. Can't see a problem there.
Take scanning. That clearly shares functionality with the fax. Don't see a problem there.
Take copying. That shares functionality with the printer and scanning, none with the faxing directly.
To me, asking these things of a multifunction unit is like asking a "multifunction" boat to float in a lake or in the ocean. It is when I try to abuse the boat that was not made to go in rough waters in an ocean do I see potential problems (in other words, treat this printer as something that can do 10000 pages of printing a month, or send/receive 1000 faxes a day, etc.)
Many of the functionality that these units share are electronic, not moving parts. I would not be surprised to learn that the components they used in a multifunction unit also had a greater MTBF of their individual counterparts, as they expect that the product will see more action per unit.
However, point well taken.

Quote from randynutts:
The problem with multi-function units is when one function goes down you're left with a second rate printer..
This is a poor man's solution at best(you're not a poor man are you, if so I apologize and will be on my way)
Buy separate units each dedicated to a specific function, better quality and if you're a careful and patient shopper great deals can be had.
"Multi-function" is so "middle class" (looking for right word or phrase here)..
