Abstract: For cleaning a restoring system of an ink-jet recorder, that ejects ink droplets from nozzles on a recording head (22) to record on recording paper (12), when a print operation is performed with an ink preliminary ejection operation which is executed at predetermined time points at least before starting the print operation and during a print operation, the system switches between first and second print operations at a predetermined interval according to a predetermined condition. The first print operation is accompanied by a first preliminary ejection operation for ejecting ink in amount of a first count value per one preliminary ejection operation. The second print operation being accompanied by a second preliminary ejection operation for ejecting ink in amount of a second count value that is greater than the first count value.

Abstract: A second passage 20 is arranged on a side opposite to a discharge port 16 relative to a first passage 18. Additionally, an intercepting member 24 is provided which intercepts the communication between the first passage 18 and the insertion port 14 and allows the insertion port 64 to communicate only with the second passage 20, at a portion of the first passage 18 near the insertion port 14, whereby the intercepting member 24 intercepts the communication between the first passage and the insertion port 14 at a prescribed timing.

Abstract: An inkjet recording ink is composed of an encapsulated water-insoluble colorant encapsulated with a high-molecular dispersant, a water-soluble organic solvent, and water. The water-insoluble colorant is at least one colorant selected from the group consisting of C.I. Solvent Yellow 21, 42, 79, 82, 83:1, 88 and 151, at least one colorant selected from the group consisting of C.I. Solvent Red 8, 49, 83:1, 91, 127 and 218, at least one colorant selected from the group consisting of C.I. Solvent Black 3, 27, 29 and 45, or at least one colorant selected from the group consisting of C.I. Solvent Blue 25, 38, 44, 67 and 70. The high-molecular dispersant is a block copolymer comprising at least one hydrophobic block and at least one hydrophilic block, which have been obtained by polymerizing vinyl ethers as monomers, respectively. The inkjet recording ink can stably record images of high fastness and excellent quality over a long period even under severe environmental conditions.

Abstract: A data communication unit (1) receives input image data of a first data format which comprises coordinate data of the end points of vectors forming an image and various modifying information of the vectors, and stores them in an input buffer (2). A data analyzer unit (3) converts the input image data into image data of a second data format and stores the data in a storage unit (6). The second data format holds the various modifying information independently of the coordinate data of the end points, decreasing the amount of data compared with the first data format. Based on the image data of the second data format, the data analyzer unit (3) generates, in a band-by-band manner, intermediate codes comprising coordinate data that constitute the contours of the vectors reflecting the various modifying information. The intermediate codes are converted into corresponding raster data in a band-by-band manner, and are printed as an image by a printer unit (10).

Abstract: An ink-jet type forming device comprising a suction fan (11) for sucking from below a platen (12), a print medium (14) that is being conveyed on the platen (12), and a variable control means for variably controlling the suction force of the suction fan (11) under a predetermined condition. The variable control means includes means that, in each scanning of a head, recognizes presence and absence of the head within a printing region ranging from the printing start position to the printing end position and that controls the suction fan such that the suction force is lower when the head is outside the printing region than when it is within the printing region, as the predetermined condition. Alternatively, it includes means that recognizes the kind of a print medium that has been set and that controls the suction force of the suction fan according to the recognized kind of print medium, as the predetermined condition. Adjustment of the suction force of the suction fan lowers the load on a conveyance motor and generally reduces power consumption and noise.
