Patent ID: 7673968

Claim:
A method comprising: a user inserting one or more consumable enclosures into one or more corresponding slots of a housing of a printing device, the printing device having a cover and a rod, the housing movable along the rod, the cover having a closed position in which the housing and the rod are inaccessible and an open position in which the rod is partially accessible; the user engaging a locking mechanism of the printing device into a corresponding feature of each consumable enclosure; the printing device detecting user engagement of the locking mechanism; in response to a user performing a consumable enclosure-related action, including moving the cover to the open position, the printing device substantially impeding user access to the locking mechanism and the consumable enclosures, in that the housing and the locking mechanism remain substantially inaccessible by the user along a portion of the rod that is substantially inaccessible by the user, until the user has entered an unlock code.
