Documents are assigned to one or more indexes in a document indexing system on the basis of document properties such as total number of tokens in the document, number of numeric tokens in the document, number of alphabetic tokens in the document, size of the document, and metadata associated with the document. The method may comprise forming a base bump, covering the base bump with a conductive bump layer and layering a surrounding material over an extended edge of the conductive bump layer. When the tracking device is adjusted into a first arrangement, the tracking device will produce a local magnetic field in the presence of the magnetic field of an MRI system that is measurable by the MRI system. In response to the user performing a consumable enclosure-related action, the printing device substantially impedes user access to the locking mechanism and the consumable enclosures until the user has entered an unlock code. To use the lower cable station function of the device, the bench is pivoted up and out of the way to the stowed position to provide access to the user end of the cable.
