I stripped mine without one to clean it and didn't have any problems.
Only two things to watch out for - the sponge on the
left hand side is soaked with ink and can get everywhere. Pull it out with a pair of long nosed pliers before you start.
The lcd screen has a small ribbon cable attached which is a bit fiddly to put back.
If the cd carrier is not loading properly thoroughly clean the bottom surface then rough it a bit to provide purchase for the rollers.
I used a nylon scourer.
