Abstract: A pump and purge valve configuration may include an inlet, an outlet arranged downstream of the inlet and defining a portion of an operational fluid pathway, and a pump mechanism arranged along the operational fluid pathway between the inlet and the outlet. The pump and purge valve configuration may also include a purging fluid pathway having a purge inlet in fluid communication with the operational fluid pathway at a point downstream of the pump. The purging fluid pathway may extend from the purge inlet to a relief point. The pump and purge valve configuration may also include a purge valve arranged along the purging fluid pathway. The purge valve may be configured to remain open unless a triggering fluid pressure develops in the pump mechanism.

Abstract: Examples describe maintenance scheduling of printhead in an image forming device by monitoring image data processed by an image forming device, determining that the image data processed by the image forming device comprises color image data, and generating a firing signal based on a mode of the image forming device.

Abstract: A cover for use in covering a seat, such as an automobile bucket seat, is provided which includes a nonstretchable portion that covers the forward surfaces of the seat bottom and back, and a stretchable skirt and cap that permits the cover to be adapted to fit a variety of sizes of bucket seats including both those of the high-back and low-back variety. The cover includes the cap, which covers at least a portion of the high-back bucket seat. The cap is stretchable widthwise to accommodate the wider width of a low-back seat and the cap, as it stretches widthwise, simultaneouly decreases in vertical dimension thereby decreasing the overall length of the seat cover so that it more closely fits a low-back bucket seat. In the preferred embodiment, the nonstretchable portion of the seat cover is a sheepskin, while the stretchable portions are made of a wool cloth having a nap similar to the nap of the sheepskin.
