Abstract: A document storage device is configured to receive a spine label. The document storage device includes a spine, a spine cover cooperating with the spine to define a pocket, and a sleeve member operable to at least partially surround the spine label to define a removable spine insert that is inserted into the pocket. The sleeve member remains in the pocket with the spine label and is removable from the pocket to remove the spine label.

Abstract: A document storage device configured to receive a title sheet. The document storage device including a cover having a cover lip and a cover sheet coupled to the cover. The cover sheet is movable between an open position and a closed position such that when the cover sheet is in the closed position, at least a portion of a first edge engages the cover lip and defines a title sheet space between the cover and the cover sheet that is configured to receive the title sheet.

Abstract: A sensing system is described for detecting the presence of ink at a predetermined level in an ink reservoir for an ink jet printer. The reservoir includes a perimetric wall having first and second wall sections, wherein at least a portion of said first wall section and a portion of the second wall section are substantially transmissive to light. A light emitter is located proximate to the first wall section and positioned at the predetermined level. A photo detector is positioned at the predetermined level and located proximate to the second wall section for detecting the light emitted from the light emitter, the light emitter being oriented to direct light at the photodetector. The light from the light emitter follows a first path when ink is present in the reservoir at the predetermined level and follows a second path when ink is not present in the reservoir at the predetermined level, the photodetector receiving the light from the light emitter traveling only one of the first path or the second path.
