摘要： Before starting printing and/or after finishing printing, a preliminary ejection of ink is performed for a cap, which covers a recording head, until the cap is almost filled (S17, S23, S38). Then, a sucking operation (S18, S24, S39) is performed to suck ink stored in the cap. Alternatively, based on a predetermined criterion such as the accumulated number of printed dots, the number of printed pages, or a print time (S71, S72), a first print operation (S73), which preliminarily ejects a predetermined amount of ink at least before starting printing or after printing, and a second print operation (S74), which preliminarily ejects more ink than the predetermined amount at least before starting printing or after printing, are alternately performed. This prevents ink from adhering to a restoring system of an ink-jet recorder and allows the sucking operation and the preliminary ejection operation to be performed smoothly.

摘要： A reference medium is scanned with a beam from a medium sensor (44) for detecting a printing medium of relatively low transmittance at high accuracy and a beam from a medium sensor (45) for detecting even a medium of high transmittance at low accuracy so as to determine edge positions Ry0, Ry1 of the reference medium. The difference Diff0 between the edge positions are calculated as a correction and stored. If a printing medium is hard to detect by means of the medium sensor (44), the medium sensor (45) is used to detect the medium, and the edge positions determined by the detection are corrected using the correction Diff0. A first drive level for driving a light source at which the output of the sensor (44) when it senses a printing medium is of a predetermined level and a second drive level for driving the light source at which the output of the sensor (45) when it senses the printing medium is of a predetermined level are determined so as to identify the type of the printing medium on the basis of the difference between the drive levels. Thus, any of a wider variety of types of printing medium can be read at high accuracy.

摘要： An ink jet system image forming device, wherein an image forming heating element (52) and a recovery ejecting heating element (54) are heated simultaneously at such a timing that air bubbles are formed in a nozzle due to a temperature difference between the temperatures inside and outside a printing head (22) so as to eject a large amount of ink simultaneously from the nozzle (40), whereby, because air bubbles and foreign matter inside the nozzle are removed together with a large amount of ink, the nozzle can be cleaned in short time.

摘要： A data communication unit (1) receives input image data of a first data format which comprises coordinate data at the ends of vectors forming an image and various modification 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 them in a storage unit (6). The second data format holds various modification data independently of the coordinate data at the ends, and decreases 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 an intermediate code comprising coordinate data that constitute the contours of the vectors reflecting various modification information in units of a band. The intermediate code is converted into corresponding raster data in units of a band, and is printed as an image by a printer (10).

摘要： A first position control member, which presses a recording sheet between a sheet conveyance roller (28c) and an image forming area, is disposed and a second position control member, which presses the recording sheet between the image forming area and a spur (42), is disposed. Thus, of the recording sheet in the course of conveyance, a portion located at the image forming area is pressed and stretched by the first position control member (34) and the second position control member (38), and an interval between this portion and an ink ejection surface is maintained at a predetermined distance. Accordingly, even if ink ejected from the ink ejection outlets is absorbed into the recording sheet, so that a fiber of the recording sheet expands, no unevenness is formed on the recording sheet. Therefore, it is possible to suppress the cockling.

摘要： An ink jet type image 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) according to predetermined conditions. The variable control means has a means that, as a predetermined condition and in each scanning of a head, recognizes presence or absence of the head in a printing region ranging from the printing start position to the printing end position and that controls 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. Alternatively, it has a means that, as a predetermined condition, 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. Adjustment of the suction force of the suction fan lowers the load on a conveyance motor and generally reduces power consumption and noise.
