thunderjet v1802s eco solvent printer The piezoelectric inkjet printer is a inkjet printer, is a large-format printers, inkjet printer press nozzle technology is mainly divided into two categories: Piezo inkjet printer and hot foam-type inkjet printer, the advantage of the piezoelectric inkjet printer precision high, reaching more than 1440dpi, long nozzle life, almost more than a year; the disadvantage is partial gray color, the machine purchase costs are higher. General use Epson 2nd generation, 3rd generation, 4th generation, 5th generation nozzle. The average life expectancy of up to four generations head 1.5-2 ten thousand square feet or more. E-PSON Piezo print head is completely controlled by the price volatility is relatively large. The difference between Thermal foam inkjet printer and piezoelectric micro inkjet printer 1. Micro Piezo technology, the nozzle is mainly suitable neutral ink, ink supply system of the machine also uses a low-cost PVC material because water-based pigment or dye-based inks were tested neutral state, the machine does not have any corrosive . Currently on the market presence of the so-called "solvent inks," because the corrosive too (mainly PVC reaction), and can not apply the nozzle technology. In fact, experts are aware of the law of ink selection is decided nozzle ink, ink decide supplies. You can not do whatever they want, and do not believe in equipment dealers boast. The first-generation Micro Piezo technology with the introduction of longer, machine to machine vendors are often trying to find a "selling point" to increase sales of the machine, but the proposal is feasible? Apply to such models or printing technology? Maybe dealers only had twelve weeks of testing, we can not wait to market conduct "solvent inks" can only be equipment dealers "tricks", so the selection of equipment and supplies to be cautious, so as not to be fooled. Micro Piezo technology uses water-based ink with neutral oil-based ink, by the use of special substrates, so accuracy is up to 1440DPI, recently Micro Piezo aqueous ink also significantly reduce the price to about 0.2 yuan / ml, it is cheaper than thermal foam inkjet printer lower cost, because the nozzle is no loss, while thermal foam models need to be replaced regularly, Sprinklers cost about 2.5 yuan per square meter. Micro Piezo ink early because of higher prices, so indoor models to NOVAJET mainly when Micro Piezo ink drops with thermal foam models are the same, because there is no nozzle loss, the latest machine speed has been improved significantly. 2. Thermal foam technology invented by HP, and the latest HP-5000 series, still use this technology, but has been applied JetExpress latest HP technology. TJI JetExpress technology is the foundation on technology, the development of a fast inkjet technology, the fastest speed of up to 52.86 square meters, but only inkjet color line drawing, that applies CAD (drawing) a map, in advertising production industry does not apply. But most concerned about is the inkjet production costs, HP and more using the original ink quality natural no problem, but the current domestic price advertising point of view, it is not practical. And hot foam sprinkler shorter life because of thermal foam nozzle, heating the wafer must provide high heat, let the ink bubbles in a very short time, and then squeeze the ink ejected, but in the long high temperature Under the changes, the ink chamber severe environmental changes in heat and pressure, the head becomes lossy. NOVAJET HP printing technology with similar, but because of the nozzle NOVAJET compatibility, so the development of alternative inks are more successful, it has been in the indoor water production NOVAJET dominant, mainly because of lower costs. Piezoelectric inkjet printer common faults and solutions
1, If the machine is turned on normally, but does not work after the computer output data, and "*" is not flashing when there on the panel may be connected to a computer and the pictures of the data cable is loose, then re-connect the data cable, Check the data cable pins have no bounce or replace cable.
2, Drops of ink or ink leakage phenomenon of the printing process, it may be two cases: Sprinklers and pin at the leak, you can pin connector at the nozzle and air cushion pad and ink tube exhausted; sprinklers within Refilling too, within the nozzle ink 20ml ~ 30ml appropriate.
3, Boot no display or LCD screen display dim unclear, but the car normal self, there may be a loose cable LCD can be seated cable or replace; it may be too low-contrast LCD screen, you can open "6
Settings Menu "- & gt;" 5 user settings "- & gt;" 7 LCD Contrast "adjusted for brightness.
4, Sometimes feel the print width is not enough, there may be paper has easy road, the first time the paper and stuck on the positive as much as possible with the jam; a "Margin" not to "expand", just go to "Settings menu "- & gt;" Paper Options Menu "- & gt;" Margin "to" expand ", must be preserved, and the option to choose just saved, for future use would not be made again.
5, When the machine pause, play paint too slow, we first check the configuration of the computer, check the computer's ECP port, after everything is normal, or come to a halt, it is best to clear the machine's memory. To do: Accessibility Menu - Service Menu - four keys on the left side of the Dir - Press 1,6,7,5,3- clear values. By the time the machine all return. Re-adjust machine settings!
6, Misting or images may be playing out of the ground is not connected properly installed ground when you can have burrs; machine quiet zone or chromatic uncalibrated, as long as the calibration can be, specific methods of operation: Accessibility Menu "- & gt; "Calibration Menu" - & gt; -; their relatively neat to preserve the value of the three thin "after the color of the dead zone test", print out a test strip, select the four-color & gt "quiet zone color menu." The difference between inkjet printers and photo machine
Photo machine and inkjet printers are large inkjet printers. Inkjet printer according to the principle can be divided into two kinds of solid and liquid inkjet inkjet, inkjet printers today's mainstream liquid inkjet printers. Liquid ink jet can be divided into bubble liquid piezoelectric. Bubble technology is through the heated nozzle, the ink bubbles, sprayed onto the print media. Ink prone to chemical changes at high temperatures, the unstable nature, color authenticity would be played to a certain extent; the other hand, since the ink is ejected through the bubble, the direction and volume of ink particles size bad master print lines the edge easily mixed, to a certain extent the print quality. Piezo inkjet technology, the ink is ejected by a thermal inkjet technology similar induction nozzles, but the ink droplets are formed by ink ejected through the narrow region to form. The narrow emission region, is emitted in the region by applying a voltage to the piezoelectric plate to one or more controlled. Because Micro Piezo print head technology is the use of crystal pressurized discharge characteristics, stable at room temperature, the ink is ejected. It has a strong ability to control the droplet characteristics, easy to achieve high precision 1440dpi print quality, and without heating Micro Piezo inkjet ink will not occur due to heat and chemical changes, it greatly reduces the ink requirements. Photo machine and inkjet printing machines are used in advertising, but in some places there are different.
Format: large format inkjet printers usually 3.2 m; small photo machine format, typically 1.52 meters.
Different working environments: outside printing machine is mainly used in large outdoor wall advertising and signs, outdoor inkjet operation, the advantage is weathering resistance, which is waterproof and sunlight can, place a long time in the outdoors will not fade discoloration. The disadvantage is poor printing quality; photo machine is mainly for indoor sticker, display inside boards, posters, posters, regulations and other indoor inkjet goods production, printing quality is relatively high
Ink: Because inkjet products placed in different environments, inkjet printers and photo machine is used in a different ink. Printer ink is a solvent-based ink, there is a strong pungent odor, waterproof shine, place a long time does not change color. Photo machine using a water-based ink. No taste, not waterproof coating needs.
Output media: inkjet printing cloth output medium is usually above the playing surface such as car stickers PVC material class media. Photo machine output medium for the PP spray adhesive paper maps.
Resolution: Printing resolution is not as high hanging aloft. Photo used indoors, must be much higher resolution. Very clear. Photo machine and printing machine nozzle basic parameters: divided into thermal foam sprinklers and micro piezoelectric nozzle are two, because it is the pictures of the most important parts. Thermal foam sprinkler nozzle is heated so that the ink bubbles, spray onto the print media in the course of this nozzle will produce losses. Require periodic replacement. Piezoelectric nozzle many small piezoelectric ceramic inkjet printer placed near the print head nozzles, using the principle that it will happen in the role of deformation under voltage, the voltage is applied in a timely manner on top of it. Piezoelectric ceramic consequent stretching of the nozzle in the ink ejection, the surface of the output medium to form a pattern. This nozzle higher manufacturing costs. Inkjet nozzle width: effective width on the market will be concentrated in the vast majority of pictures of 130 cm (50 inches), 152 cm (60 inches), 160 cm (64 inches), 180 cm (74 inches) or so, in order to 160 cm of the machine on the market most sensitive. 1.27 m below the screen where the majority. Width divided paper width (also known as the material width) and solid spray width (working width), the former tend to be large 1 inch (2.54 cm) or more. Accuracy (resolution): photo machine precision is generally 720DPI, inkjet machine precision indicators describing general use dots per inch, that DPI (Dotsperinch), the accuracy is determined by the nozzle. Along with the simultaneous development of these technologies is meaningful for the practical application of the general advertising graphics 600DPI to 720DPI accuracy is sufficient. Higher accuracy may be only selling products only. In fact, many users in the use of advertising 360DPI, 540DPI, 720DPI8PASS is the highest output mode, and go up in the details, you must use in order to reflect the effect of the original supplies slightly, print quality improvement is not clear how, but will print speed greatly reduced, more importantly, the loss is too large nozzle, Zenga unnecessary costs, it is worth the move.
Output speed: factors affect the actual printing speed are: A: Printing Equipment pure speed, B: software RIP speed, C: data transmission speed, drying time.
Consumable costs: direct costs by printing inks, substrates, nozzle wear, film and other items constitute a rejection rate. Consumable costs usually only refers to the sum of the first four. Different brands and models of inkjet ink consumption unit is different, it is estimated that the unit area HP, the amount of ink than ENCAD ROLAND, MIMAKI large amount of the ink, but the price should be slightly higher compatible ink, overall ROLAND , MIMAKI use cost or lower than HP, ENCAD. Guan Jian, compatible ink also decide the merits of key rejection rate and nozzle loss.
Color: Not more vivid the color, the better, the color gamut is good or bad depends on the size of its energy performance and restore consistency (gamut of uniformity). The quality of color should be divided into indoor and outdoor two cases to analyze the judge. In general, a large indoor ink color gamut, printing effect is more beautiful for some, but outdoor ink is darker than the gray.
Outdoor UV resistance: This performance is mainly used by the ink of the decision, all manufacturers of original ink basically not common, so each machine performance UV inkjet inks of different effects are not the same. Photo machine nozzle plug approach
Inkjet photo machine when the machine no ink nozzles, resulting in lack of color screen content, often referred to as "nozzle clogging", especially for Scitex class screen machines are the main factors affecting the quality and yield. Nozzle clogging discuss the reasons contribute to a better understanding of the machine and improve picture quality.
Photo machine heads principle is quite something like a bicycle pump frequently used in our daily, one last look Movement hardcore pump nozzle is our soul parts --- piezoelectric crystals, when you find pump outlet when not playing, no more than two reasons: the gas pump iron road barrier or does not work.
Pump nozzle of course much more complicated than that, so "jam" is a variety of reasons, generally have the following situations:
1, The ink in the photo machine heads accumulated to a certain extent out of the orifice is clogged: is the most common way to plug because the ink solvent must evaporate into the air in order to make the picture becomes dry, so the ink is a volatile liquid in the air and clarity of volatile solids. When the spray orifice cloth inkjet, always leaving a part around the ink, this part of the ink after drying in air injection holes will slowly become smaller even close off the spray orifice, but because it is outside the nozzle hole, it is easy clean, and this is the reason why we often wash nozzle.
2, Piezoelectric crystal damage: Definitely not the ink jet nozzle, the general use of piezoelectric nozzle about a year, a lot of effort in printing plants may also use less than a year is normal.
3, The piezoelectric crystal fatigue damage: the phenomenon is sometimes inkjet photo machine heads, and sometimes not spray ink, especially when large-jet (ie when the spray dark picture) "jam" phenomenon obviously, at this time the best way is replaced with a new nozzle.
4, Filter blockage caused no ink within the nozzle nozzle: nozzle used longer, especially in the printing task without full shutdown of the plant often at night, the ink does not flow in the nozzle in a longer time, is easily adsorbed in the interior of the filter network or walls of the ink channel, so that the cross-sectional area of the ink flow becomes small nozzles can also cause no ink phenomenon.
5, The viscosity of the ink is too high or too low: too high viscosity of the ink the fluidity of the ink is poor, the amount of ink per unit time sprayhead enough; viscosity of the ink is too low, that is too thin, easily pressed against the nozzle orifice Withdrawing transistor when inhaled air can not absorb ink, which is emitted by air; both of which cause no ink nozzle phenomenon. This often requires the customer is located ink environment is important, the case of using the ink should be placed in front of the environment using the ink more than 24 hours as well, because the ink is placed at low temperature viscosity will be high, while the viscosity at a high temperature will becomes low, the viscosity varies widely, once a large mixed use ink viscosity differences, it will cause no ink jet phenomenon
6, The drive circuit fault: the drive circuit electronic components aging and savings too dry ink dirt, may affect the driving voltage nozzle, resulting in an unstable nozzle no ink or ink.
7, The type of ink: some manufacturers of ink due to improper control of the amount of desiccant drying too fast, easy to cause the ink to plug in an external, although can be cleaned, but more frequent cleaning intervals, once a long time without the use of sprinklers and no time When protection nozzle, spray painting in the next time may cause permanent damage to the nozzle. |
