Abstract: An inkjet printer (10) has a movable carriage (12) supported above an ink-receiving medium by a rail (14) defining a carriage axis. A cartridge holder (16) is mounted on the carriage and having at least one cartridge compartment (18), each of the at least one compartment having a compliant compartment wall (82). Each compartment is providing with an opening at one end (19) of the carriage floor for receiving the snout (72) of an ink jet printer cartridge (20) on which is mounted a nozzle plate with more that one nozzle for depositing ink onto the ink-receiving medium. Each compartment is also provided with equalizing structure for maintaining the cartridge substantially perpendicular to the carriage axis when the compliant compartment wall is deflected by a spring at the middle of the compartment forcing two datum surfaces on the cartridge against front and rear supporting surfaces on the compartment wall. The equalizing structure preferably includes a second opening (21) at the other end of the floor.

Abstract: A high density graphics image can be printed without smearing by contact with a second page, without any unnecessary reduction of throughput. Throughput enhancement logic is inhibited during the printing of the second page for a variable delay related to the image density of the first page. The variable delay is calculated as a linear function of both the density (relative to a predetermined grid size) and the location if the densest portion of the first page, using coefficients which are different for different print modes. In one preferred embodiment, a maximum density is calculated by counting drops of ink in each of several overlapping grids, and the magnitude and location of the maximum density grid on a prior page is used to limit the throughput of a next page until a sufficient delay has elapsed to ensure that ink on the prior page will not be smeared when it comes into contact with the next page.

Abstract: An improved electrical interconnect system for a flexible circuit which includes: a flexible first layer; at least one protrusion on the flexible first layer that has an electrical contact; a second layer having at least one electrical contact; and a spring apparatus coupled to the flexible first layer and to the second layer for pressing the electrical contact on the protrusion on the flexible first layer to the electrical contact on the second layer to electrically connect the electrical contact on the protrusion to the electrical contact on the second layer. In a specific embodiment the spring apparatus for pressing the electrical contact on the protrusion of the flexible first layer to the electrical contact on the second layer includes relief for allowing the flexible first layer to deform during assembly of the improved electrical interconnect system for a flexible circuit.
