1. A printhead comprising: a jetting module that forms drops; a catcher; a deflection mechanism that deflects some of the drops toward the catcher; and a moveable sealing mechanism having a first position in contact with the catcher and a second position removed from the catcher that permits drops to travel past the catcher, the moveable sealing mechanism including a first portion that that is fixed to the printhead and translates the sealing mechanism relative to the catcher, and a second portion that is removably fixed to the first portion and cooperates with the catcher to form a seal when the sealing mechanism is in the first position, the first portion of the sealing mechanism including at least one magnet and the second portion of the sealing mechanism including at least one magnet that are positioned relative to each other such that they attract to one another to removably fix the second portion of the sealing mechanism to the first portion of the sealing mechanism, the first portion of the sealing mechanism and the second portion of the sealing mechanism each including registration features that align the first portion and the second portion relative to each other when the registration features engage each other, wherein the at least one magnet of the first portion of the sealing mechanism and the at least one magnet of the second portion of the sealing mechanism are offset relative to each other in a direction to impart a force in that direction that causes the registration features of the first portion of the sealing mechanism and the second portion of the sealing mechanism to engage each other.
