    摘要： Automatic print rate-controlling and pen-servicing method and apparatus are described for power management and for determining appropriate servicing intervals for plural-pen ink-jet printers. The preferred method involves counting the number of drops of ink that are fired from each of plural pens in the printer's printhead carriage and optionally calculating the pen firing rate such that printer throughput can be controlled to limit time-averaged power and such that pen servicing frequency can be based upon the need for such servicing. The counts are maintained in memory connected, for example, with the printer's microcontroller, as are parameters that the microcontroller uses to determine appropriate drop count-based print rate controlling or pen servicing that reduce printer throughput only to the extent necessary. Particularly, the pens are serviced when any of the counts is within a predefined finite range of a predefined number or no later than when any of the counts exceeds a corresponding predefined number. The preferred apparatus includes a drop counter, a service station for wiping and spitting plural pens within a printhead carriage and a controller responsive to the drop counter to control the printing rate and to move the printhead carriage into operative association with the service station based upon drop count, firing rate, time-averaged power capability, printhead location and other predetermined criteria.

    摘要： A synchronized wiper and pen motion solution for ink-jet printers is described. The invented method and apparatus synchronize the motion of the pen and wiper throughout the wipe stroke, and provide for controlled, simultaneous movement therebetween that avoids pole vaulting, excess interference and ink flicking. Such is accomplished by moving the carriage to a defined position shy of a wiping position above the service station including a sled mounting the wiper; raising the sled to produce a proper interference fit between the wiper and the pen while simultaneously moving the carriage at low speed; continuing the wipe stroke by high-speed carriage movement with the sled stationary; and, at the end of the stroke, lowering the sled to clear the wiper from contact with the pen before reversing carriage motion. The solution lends itself to single- or plural-pen ink-jet printers.

    摘要： A misalignment compensation technique for a dot printer is disclosed. This technique first supplies printing instructions to a printhead for energizing printing elements in various groups (primitives) to print a pattern on a medium. The printed pattern is then detected by optical sensors in the printer. Based on the detection, a position offset error for each primitive is determined. These errors are used to generate a separate time correction for each of the primitives such that, when the printer is used normally, the time period for printing a dot will be advanced or delayed for each primitive so as to align the dots printed by the primitives. In another embodiment, alignment data taken by a manufacturing line sensor is stored in a memory on the print cartridge. After the print cartridge is installed in the printer, a second optical test completes the data needed to create timing correction values.

    摘要： In a method and system for delivering ink within a printer, a reservoir and a portion of a tube are accelerated so as to generate an inertial flow of ink in the tube, where the tube is connected to the reservoir and in fluid communication with an ink supply. A valve is provided between the tube and the reservoir. The valve is closed to retain an amount of the inertial flow of ink in the reservoir when the inertial flow of ink is away from the reservoir. The tube is primed by moving the printer so as to elevate the ink supply relative to the reservoir in the printer. Foam may be provided within the reservoir which restricts the rate of flow by not allowing ink to be conducted from the reservoir when the foam is unsaturated.

    摘要： In the preferred embodiment, an inkjet printer includes a replaceable print cartridge which is inserted into a scanning carriage. The print cartridge contains a regulator valve. An ink tube extends from the scanning carriage to a separate, disposable ink supply cartridge located within the printer. A second valve connected between the ink tube and the ink supply cartridge is automatically actuated when it is determined that the printer is not being used. The valve seal is more reliable than the inexpensive one-way valve seal in the disposable ink supply cartridge. The reliable valve seal prevents any air bubbles in the tube from expanding toward the ink supply cartridge, enabling the use of more flexible tubes which have less stringent air diffusion characteristics. In another embodiment, instead of a valve, a pressure source is connected to the ink tube to maintain the partial air pressure within the tube at approximately ambient pressure.

    摘要： To maintain a uniform spacing between the print media, such as paper, and an inkjet printhead having a large print swath, for instance about 25 millimeters (one inch) wide, a new media support system is provided for inkjet printing mechanisms, such as printers or plotters. The support system employs an endless belt driven from the belt interior surface by a roller drive system that uniformly supports the print media under the reciprocating printhead. The belt may be lined with anti-cockle ribs to support the media when saturated. The belt may also be foraminous, with a vacuum applied thereunder to pull the media onto the belt. A method is also provided for supporting and transporting a large sheet of print media through a printzone of an inkjet printing mechanism, such as an inkjet plotter, that uses such a large swath inkjet printhead.
