Problems solved by technology

However, in this case, when high-speed printing is performed with high precision, high-precision control is required, which is technically difficult
In addition, when using a full-line print head, the number of nozzles is huge, and there will be problems with the print head due to malfunctions such as nozzle clogging and collapse, and the quality of the image will deteriorate.
When a nozzle misfiring occurs, the problem is very difficult to fix, requiring the printhead itself to be replaced, reducing the productivity of the printing system to zero before the replacement is complete

example example 1

[0139] exist figure 1 In an ink jet recording apparatus shown, the ink tanks connected with four independent ink jet heads are filled with four kinds of inks. (For ink, positively charged color particles with an average diameter of 0.7 to 1.0 μm are dispersed in ISOPARG. Carbon black, phthalocyanine dye, CI red pigment, CI yellow pigment can all be used as pigments for color particles.) Figure 9A 150dpi, 833-channel head (channels arranged in 3 staggered rows at a density of 50dpi) shown in is used as the inkjet head, and a silicone rubber heated roller incorporating a 1kW heater is used as the fuser element. The ink tank is equipped with an immersion heater and a stirring impeller as ink temperature control elements. The temperature of the ink was set at 30 °C, the stirring impeller was rotated at 30 rpm, and the temperature was controlled by a thermostat. Stirring impellers are used as stirring elements to prevent settling and coagulation. The ink channel is made transl...

[0142] exist Figure 7 In the inkjet recording device shown, a Figure 11 A 200dpi head with 601 channels (configured in four staggered rows with a channel density of 50dpi) shown in is used as an inkjet head. A heating roller made of Teflon (R)-coated silicone rubber with a heater of 0.8 kW was used as a fixing member. A belt made of a metal belt bonded to a polyimide film was used as the conveyor belt. One end of the belt is optically read by a conveyor position detection element and the position control element is driven to image at 1800dpi. The other conditions of imaging were the same as those in Example 1. Imaging problems due to dust etc. are not visible at all, nor is image quality degradation due to problems such as changes in ink dot diameter due to drastic temperature changes and increased printing time. Therefore, high-quality printing can be achieved, and the obtained printed documents have extremely clear images free from linear unevenness and burrs. Example...

example 3

[0143] exist Figure 8 In the device, the Figure 23 1200dpi, 10" wide full line head-type channel printhead shown. Other condition settings for imaging were the same as in Example 1. Imaging problems are virtually invisible, as are image quality degradations caused by issues such as drastic temperature changes and dot diameter changes as the number of copies printed increases. Therefore, full-color printing on one side and two sides can be realized.

[0144] After printing is complete, the ISOPARG on the printhead is cycled to perform cleaning, and further cleaning can be performed by contacting the distal end of the printhead with a non-fibrous cloth containing the ISOPARG. In this way, after three months, good printed material can be produced without any maintenance operations. In addition, when a nozzle fails to eject ink, it is interpolated by other nozzles using the previously described method without performing elaborate cleaning. One result of using adjacent nozzl...

Abstract

An inkjet recording device and inkjet recording method capable of forming a high quality image with a simple structure. A transport belt position detection component detects a position of an end portion of a transport belt and outputs the detected position to a system control section. A recording medium position detection component detects a position of an end portion of a recording medium and outputs the detected position to the system control section. A position control component is capable of moving on the basis of instructions from the system control section for movement across a transport direction.

Description

technical field [0001] The present invention relates to an inkjet recording apparatus and an inkjet recording method. Background technique [0002] As far as forming a print image on a print medium based on an image data signal, there are electrophotographic technology, sublimation type and fusion type thermal transfer technology, inkjet technology, and the like. Electrophotography requires a process of forming an electrostatic latent image, which is achieved by exposing a photosensitive drum to a static charge. The system is thus complicated and the equipment is expensive. Using thermal transfer technology is inexpensive equipment, but because of the ink ribbon, running costs are high and waste is generated. In contrast, with inkjet technology, printing is directly achieved on a recording medium by jetting ink only to the portion to be imaged using an inexpensive device. As a result, colorants are used efficiently and the operating costs are cheap. [0003] For printing...
