    摘要: The present invention relates to a method that enables image quality of a printed image to be maintained by reducing unintended variations in drop volume, through the adjustment of ink drop ejecting conditions depending on the amount of ink remaining in an ink tank chamber or reservoir, and/or the ink demand for printing an image. The method of printing of the present invention comprises: providing a printhead in fluid communication with an ink chamber or reservoir; detecting at least one parameter related to an amount of negative pressure provided to the printhead; and adjusting an ink drop ejecting condition of the printhead as a function of the parameter so that an amount of variation in size of ejected ink drop is reduced.

    摘要: The present invention relates generally to the field of inkjet printing, and in particular to a method of printing that provides improved ink usage efficiency. In the method of the present invention a threshold level of ink in an ink chamber or reservoir is stored. The remaining amount of ink in the ink chamber or reservoir is monitored and compared to the threshold level. When the remaining amount of ink in the ink chamber or reservoir is below the threshold level, an ink throughput through the printhead for a printed image is reduced.

    摘要: Film scanning apparatus having a film cartridge chamber for receiving a film cartridge containing photographic film having images to be scanned, a film takeup chamber and a film scan gate therebetween. The apparatus has an upstream nip roller set positioned between the film cartridge chamber and the film scan gate and includes at least one drive roller and pinch roller set in which the drive roller has a compliant film engagement surface. A downstream nip roller set is positioned between the film scan gate and the film takeup chamber and includes at least one drive roller and pinch roller set in which the drive roller has a compliant film engagement surface. The upstream nip roller set exerts constant tensioning force on film in the film scan gate buffering the film in the film scan gate against variable tensioning effects on the film caused by the film cartridge. A drive motor is directly connected to the downstream drive roller set and the downstream roller set is drivingly connected to the upstream drive roller set by an elastic drive belt. A differential compression force is exerted on the pinch rollers such that the force on the downstream pinch rollers is greater than on the upstream pinch rollers thereby causing a film speed differential between the upstream and downstream roller sets that maintains a desired degree of tension on film transported through the film scan gate.

    摘要: Embodiments of a printing device fluid reservoir with gripping features are disclosed. In an embodiment of the present invention, the fluid reservoir includes a first surface and a fluid-containing body located beneath the first surface. According to an embodiment of the present invention, the first surface includes a protruding grip, and the fluid-containing body has a lever extending therefrom. According to an embodiment of the present invention, both the protruding grip and the lever are configured to receive a pinching force that compresses the lever towards the fluid-containing body, facilitates carrying of the fluid reservoir, and facilitates installing and/or releasing the fluid reservoir into/from a chassis of the printing device.
