Abstract
An imaging apparatus includes a housing having a cartridge exchange opening, and a printhead carrier system contained in the housing. The printhead carrier system has a printhead carrier. A cover is pivotably attached to the housing. The cover has an engagement surface. When the cover is in a closed position the cartridge exchange opening is not exposed. A switch unit has a switch actuator and a switch. The engagement surface of the cover is positioned to engage the switch actuator when the cover is in the closed position. The switch actuator is configured with a button that is accessible by a user to facilitate manual manipulation of the switch actuator by a force applied to the button by the user. The printhead carrier is positioned based on an output of the switch.
