摘要： Ink tanks and recording devices incorporating the ink tanks comprise a free ink chamber, and a negative pressure generating chamber in the ink tank. The negative pressure generating chamber comprises a floor member comprising at least one projection extending along at least a portion of the floor member, and a porous material, wherein the projection of the floor member is configured to engage the porous material to inhibit the creation of an air flow path between the porous material and the floor member. The ink tank further comprises a partition wall disposed between the free ink chamber and the negative pressure generating chamber and configured to allow the flow of ink from the free ink chamber to the negative pressure generating chamber.

摘要： A system and method for identifying and reducing power consumption in a rendering device based on an inactivity period. Historical data based on a customer usage pattern can be analyzed to detect the inactivity period (e.g., end of day) and to intelligently force the device into a lower energy state. A sleep and low power time can be calculated and a sleep and low power time out period can be reduced to a minimum value based on the inactivity period.

摘要： A removable ink tank configured to be mounted to a printhead assembly includes a floor having an ink output port A free ink chamber is located above the floor. A suspended ink chamber is located above the floor and around the ink output port. The suspended ink chamber is separated from the free ink chamber. At least one ink suspension body is contained in the suspended ink chamber. A fluid communication port is formed between the free ink chamber and the suspended ink chamber to facilitate a fluid communication between the free ink chamber and the suspended ink chamber. A filter device is positioned to cover the fluid communication port. The filter device has a porosity selected to establish a desired bubbling pressure between the free ink chamber and the suspended ink chamber.

摘要： A removable ink tank includes a floor including an ink output port. A free ink chamber is located over the floor. A suspended ink chamber is located over the floor and around the ink output port. The suspended ink chamber is separated from the free ink chamber by a divider wall. The divider wall has an ink communication port located near the floor to facilitate fluid communication between the free ink chamber and the suspended ink chamber. A frame is formed around the ink communication port. The frame protrudes outwardly into the suspended ink chamber to ensure a good seal with the ink suspension member.

摘要： An ink tank for an inkjet printing device that includes a housing for containing ink, first and second chambers within the housing, and a partition separating the first and second chambers. The ink tank also includes a communication port connecting the first chamber in fluid communication with the second chamber, a tank outlet disposed within a wall of the housing, and a high capillary pressure producing member in direct communication with the outlet. The ink tank may be configured such that the ink may flow from the free ink space through the capillary pressure producing member and exit the outlet without having to travel through the communication port.

摘要： A micro-fluid ejection head assembly having improved assembly characteristics and methods of manufacturing a micro-fluid ejection head assembly. The micro-fluid ejection head includes a fluid supply body having at least one fluid supply port in a recessed area therein. A reinforcing member circumscribes the fluid supply port. A micro-fluid ejection head is attached with an adhesive to the supply body in the recessed area so that cracking of the ejection head during adhesive curing is substantially reduced.

摘要： Printer (1) feeds paper or other media sheets (5) to pinch rollers (9a, 9b), which further feed the sheets into an imaging station (7). Pressure rollers (9b) are held by plate 22 which is biased by a spring (33) and pivots on extensions (37a, 37) to moves pressure rollers (9b) into nip relationship with nip roller (9a). To evenly distribute the forces across pressure rollers (9b), plate 22 is weakened by depressed lines (27a, 27b) located between the spring and the pressure rollers (9b).
