A fluid reservoir wiper assembly has a fluid reservoir for storing a fluid. There is an inserter for insertion into the fluid reservoir. A wiper for wiping fluid from the inserter has a first wiping position and a second wiping position within the fluid reservoir. The first wiping position is closer to the inserter than the second wiping position. A block is configured to be disposed between the wiper and the inserter. The block is configured to selectively allow the wiper to move between the first wiping position and the second wiping position.
