does Rashi ask that if the proofreader is checking and makes a mistake in the reading, is he yotzei? then what is tosofot looking for? is the question, just because someone is proofreading, doens't mean that someone is looking to be yotzei, and therefore isn't?

Claire,
Rashi is not asking a question; he is explaining the Gemara's question and answer. The Gemara disproves its initial assumption that the Mishnah is saying that Mitzvos Tzerichos Kavanah. Rather, even if one does not need Kavanah to be Yotzei, he at least needs to do an act of reading. The Mishnah then is saying that one who is not even "reading" the Parshah of Shema, but merely "scanning" the Parshah as it is written in the Sefer Torah for errors, does not fulfill his obligation of Keri'as Shema. Tosfos questions this, because "scanning" for errors is no different than reading without intent to fulfill the Mitzvah.
Is this clear?
