    Abstract: A low ink sensing system is combined with an ink cartridge detection system to enable a more efficient ink jet printer. An ink container which supplies ink to an associated printhead is modified by the incorporation of two light directing elements, in the preferred embodiment, a faceted prism and a roof mirror, into a transparent wall of the container housing. The cartridge, comprising the ink container and associated printhead, is mounted on a scan carriage. Periodically, the carriage is conveyed to a sensing station comprising a pair of light sources and a commonly used photosensor. A first light source is energized and a beam of light is directed to a location where the roof mirror, would be positioned if the cartridge is present. If the cartridge is absent, lack of a reflected return signal is sensed, indicating a cartridge has not been inserted. Print operation is halted until a cartridge is inserted. If a cartridge is properly inserted, the roof mirror returns most of the incident light to the photosensor which generates a signal indicating the presence of the cartridge. A second light source is then energized and directed towards the faceted prism, which is either immersed in ink or exposed to air within the interior of the container. If the latter, light is internally reflected by the prism facets back to the photosensor. If a print operation has been in progress, and the ink level has fallen, the common photosensor detects either a strong or weak redirected light component and initiates a status check and generates appropriate displays of low ink level or out of ink warnings.

    Abstract: An ink smearing preventing method of terminal equipment of inkjet output device resolves the drawback of the ink smearing which is caused due to ejection prior to ink drying during data printing onto paper, for which the ink smearing preventing method is provided to a printing manner where the next line is systematically printed regardless of the amount of ink sprayed, to adjust the printing speed such that the paper is ejected after the sprayed ink dries, by regulating the printing time of the next line according to the amount of ink, after determining the amount of ink sprayed. Meanwhile, the ink smearing preventing method includes the steps of determining whether there is data to be printed in the terminal equipment; calculating the dot number of the ink required for printing the data in a predetermined unit if there is data to be printed; printing the data in the predetermined unit on paper by initiating actuation of a timer corresponding to the calculated dot number; determining, after printing, whether the actuation of the timer is completed, and moving the paper as much as the predetermined unit if actuation of the timer is completed. Here, the timer corresponding to the calculated dot number is databased and preset in the memory of the terminal equipment, to a numerical value that is proportional to the data dot number for printing black ink. Accordingly, by determining the amount of ink used, when printing data in an inkjet type terminal equipment, and by adjusting the print time of the next line according to the determined amount, it is possible to regulate the printing speed such that the paper is ejected after the sprayed ink has dried. Therefore, there is the advantage of preventing data loss that may occur from the user's carelessness.

    Abstract: A computer-controlled system for producing a multi-color image on a substrate using multi-colored cholesteric liquid crystal (CLC) pigment materials made from CLC flakes tuned to predetermined bands of color. An image generator automatically generates an image specifying a pattern over which binder material is to be applied to a substrate by a binder material applicator. A plurality of CLC pigment applicators automatically apply patterns of different-color CLC pigment material to the pattern of binder material, which binds thereto as the binder material dries according to its drying characteristics. An output device is used to automatically return the substrate to a different one of CLC pigment applicators after each application of a pattern of different-color CLC pigment material to the pattern of binder material. The output device automatically repeats the return of the substrate to the CLC pigment applicators until all bands of color in the multi-color image are rendered.

    Abstract: According to the position information, based on the encoder signal, about the print heads during movement which is obtained in connection with the print start timing of the signal used by the print heads to print the registration adjust patterns, the amount of registration deviation between the print heads are determined. Then, the differences between the print start time of the signal and the leading and trailing edge of the encoder signal are determined for each print head. The difference between these differences is adjusted as the deviation amount between the heads to adjust the ejection timing of each head. This can correct the print position deviations between the plurality of the heads with high precision without being influenced by variations in the head movement speed.

    Abstract: An inkjet printhead chip structure and a method of estimating the working life through the detection of any defect on the chip structure. The method includes laying a metallic layer such as a tantalum layer over the chip and then shaping the metallic layer into a protective layer circuit. A portion of the metal protective layer covers the heating elements embedded in the chip. In printing, the heating elements heat up the ink to produce jets of ink. However, a portion of the heat is transferred to the metal protective layer thereby raising its temperature. Heat on the metal protective layer combined with any strayed residual ink bubbles that impinge upon the surface of the metal protective layer causes the metal to age. Since resistance of the metal protective layer will increase proportionally to the amount of aging, a measurement of the resistance is capable of estimating how much longer a given chip is suitable for use. Furthermore, if this special circuit layout runs across each long side of an ink slot, any cracks along the direction of the ink slot are detectable during resistance measurement.
