Embodiments of a printer cartridge with a moveable shutter for covering the organic photoconductor are shown and described. The cartridge and the cavity inside the printer, which receives the cartridge, cooperate to open the shutter, preferably when the cartridge is slid longitudinally into the printer. A protrusion and ramped recess system may be used to create the force to move the shutter, the cartridge translating the force of sliding the cartridge longitudinally into a transverse force on the shutter. In a preferred embodiment, the shutter has a protruding tab that is placed to fit into and slide along a diagonal elongated recess in the cavity wall of the printer. When the cartridge is inserted longitudinally into the printer, the force of the recess wall on the tab moves the tab and hence the shutter to open the shutter. Likewise, when the cartridge is removed from the printer, the tab movement in the recess either forces or allows the shutter to return to the closed position. Thus, insertion of the cartridge and opening of the shutter are accomplished all in one single longitudinal sliding action by the user, and do not require rotation or additional adjustment of the cartridge or the shutter.
