Description of the invention (filjL background The present invention relates to a printer, f framing; ; Electrostatic image printer for printing multiple colors. This early image printer is well known, in which the color image is statically formed on a rotating endless surface, such as a belt or drum, and the final transfer ί On the receiving material, the material is usually-paper or mesh. ^ US Patent No. 4,796,048 (Loy F.

In the disclosed embodiment, in the state color The solvent in the powder is removed when the toner image is carried by the belt, which is radiated and emptied. Then the image is transferred to the base layer by heating and pressing, and then the belt is It is cooled before receiving the image. Application W〇92 / l〇793 (Spectrum Science and Technology BV) reveals an imaging device, in which the liquid toner image is formed in a single-piece photoconductor 'and then the image is transferred to a transfer element in the form of a heated transfer barrel , And the transfer cylinder is transferred to a base layer. The plane on the heated transfer cylinder can be cooled before the image is distributed. A variety of images are distributed on the rotary cylinder one by one, that is, each transfer cylinder Rotate once to apply a color—Λ image on it. Before the transfer cylinder applies the next color image, the plane of the transfer cylinder must be cooled to prevent the toner from returning to the light conductor Occurs. The color stepping is slow, especially due to the limitations of the image writing system itself.

Description of the invention (2) Over 25% of the writing speed of the shirt image In the device proposed by Spectrum Corporation, one toner developing unit will be contaminated by another color powder3. Therefore, the device proposed by Spectrum Corporation includes a very clear cleaning system for photoconductors. In any case , We are more inclined to avoid using the aforementioned liquid toners used by Bain and Spectroscopy, especially those based on water-insoluble solvents, such as IS0par (trademark), whose main ingredient is decane. Because of environmental protection Reasons for 'these solvents are not allowed to be released into the atmosphere at will, so a special device is needed to prevent the release of these solvents. Copiers and printers that use powder toners have been proposed. For example, US patents No. 5059990 (Abru et al./All Green Company) revealed _ printers that print multiple colors, and one of the receiving materials is moved on the circulation path and carried with the single-piece toner image The light guide belt contacts, and toner image powders of different colors are sequentially deposited on it. This multiple-printer printer has great difficulty in applying toner images of different colors to the receiving material, and it has the same problem of speed limitation as the device proposed by the aforementioned spectroscopy company. U.S. Patent No. 5119140 (John S. Burke et al./Full Record Company) discloses a device where most of the powder toner images are sequentially distributed on the image receiving device to form a variety of color powders on it Image 3 The multi-color color powder image is then transferred to a flat paper using an electrostatic device. The efficiency of transferring an image to the base layer electrostatically depends on the nature and conditions of the base layer, and is not 100% effective. For this reason, Burke and others need to provide a cleaning device to clean the figure before the next image of the Buddha. This paper size is applicable to the Chinese National Standard (CNS> A4 specification (210X297 mm) ^-( Please read the precautions on the back and then fill out this page), v5 line A7 B7 Printed 318216 by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economy V.

This structure creates a huge problem, that is The correct address and speed limitation of the color image are the same as the problems faced by the aforementioned device of Abru et al. In U.S. Patent No. 5455668 (Di Burke et al./Secon Nv), two types of single printing are exposed A variety of color table printers, where the base layer is mesh-shaped and can pass through most toner image forming stations, where images of different colors are spread on it.

Before transferring multiple colors to the base layer, first heat the multiple toner images on the moving transfer member;-The transfer element transfers the multiple toner images to the base layer After cooling :: Sending the component, and then when the cloth color powder is advanced on the component, the temperature of the " Hai component is lower than the temporary temperature Tg of the glass of the color. Heating device for child transfer components May include infrared light-fired heat devices' although other types of heating devices are also feasible, including HF light-fired, convection heating and conduction heating, such as the use of heated rollers, etc., which are suitable for images with multiple colors on them The heating of the transfer element is very important =. Especially, when the color image plane touches the base layer, its temperature must be higher than the melting point temperature of the toner to ensure that the powder particles of different colors are printed by the Employee Consumer Cooperative of the Central Nuozhun Bureau of the Ministry of Economic Affairs. The system can be mixed, so that the mixed multi-color powder image can be transferred to the base layer, and the image on the base layer can be shaped.

Description of the invention (6) The temperature is also very important. In particular, the surface temperature of the transfer element must be reduced to the temporary temperature Tg of the glass of the toner, for example, cooling to room temperature. The function of the transfer element is to transfer multiple colors of toner images Transfer to the base layer. Therefore, there is no need to provide a light-conducting plane on the transfer element. In fact, heating or cooling the transfer element on the device according to the present invention means that traditional photoconductor materials will not be used because of this photoconductive material The light guide characteristic of is very sensitive to temperature changes. The transfer TL element can include an outer plane, which is composed of a material with low surface energy, such as silicon Sexual body (typical surface energy is 20 dynes / cm), tetrafluorinated polyethylene, fluorinated polyglycosamines and other fluorinated copolymers. The transfer material is preferably a low-quality type, so it is The color toner image can be completely heated before it is transferred to the base layer 'and can be quickly cooled before being transferred to another multi-color toner image by the main belt. For this reason, although the transfer element It can be transfer roller or chrysanthemum, and the best type is the transfer belt type. By pointing out that the toner images of multiple colors and powders are distributed to the transfer element at the same time, we mean (select 丨) the multiple colors. The toner image is first formed on another component, and then applied to the transfer component, or (option 2) using a majority of toner image application device, and the toner image is applied along the path of the transfer component At different positions. In the latter implementation, the toner image application device is controlled in relation to each other to ensure that the different images are applied at the correct location. Therefore, according to one of the inventions In an embodiment, the transfer element is an intermediate transfer element, and the device for forming a multi-toner image on the transfer element includes the ft scale of this paper and the Chinese National Standard (CNS) A4 specification (210X297 mm) I 1 --- --- Ιτ ------ ^ (Please read the precautions on the back before filling in this page) Printed by the Central Government Bureau of the Ministry of Economic Affairs, printed by the employees ’cooperatives. Description of the invention (7)-Main transfer element; " The device is used to guide the main transfer element through a set of toner image generating stations' where most of the toner images of different colors are brought together to form A multi-color color powder image is formed on the main transfer element, and the intermediate transfer element is in contact with the main transfer element downstream of the image generation station, wherein the multi-color color powder image is electrostatically written by the main transfer element to On the middle transfer element. In this embodiment, the main transfer element is preferably constituted by a main belt. For example, the main belt may have a toner image carrying plane, which is composed of a non-conductive material. The non-conductive material is preferably selected from polyethylene terephthalate, silicon elastomer, polyamide (e.g. KAPTON_ trademark), and mixtures thereof. The main belt can be composed entirely of these materials or it can be made of a substrate and then coated with a layer of non-conductive material on the surface. The basic material of the main belt may be metal, such as stainless steel, polyamide, polyethylene fluoride, polyhydric ester, or a mixture of 3 polyvalent esters, which has good mechanical and electrical characteristics and is not very sensitive to humidity. ”Under the theory of non-holding, our understanding is that it is best to transfer the toner image from a material with a lower surface energy to a surface with a higher surface energy a. This can reduce the shearing of the toner particles during the transfer process. Force effect, and make the transfer process more efficient, and leave the residual toner on the donor plane. Ideally, the surface energy of the two-body plane must be lower than the surface energy of the acceptor plane. This: by applying the image Transferred by the transfer element to the base layer, because the surface amount of the base layer, for example-the surface energy of the sheet of paper does not exceed approximately 45 dynes / cm.

In the case of β7 shirt, the whole transfer will be faster. Yu Zheng The invention needs to transfer to make the transfer efficiency to the base layer higher. It is known that the image is heated, but the multi-color color image is made by the main belt When transferring to the transfer element, if the transfer element has a D & ^ D ^ Tonggan low surface energy, this transfer operation becomes more difficult. Therefore, heating the main belt before the main belt leaves the last image generation station and contacts with the intermediate transfer magic cow, Good results will be obtained, but the risk of excessive temperature will occur. However, according to the present invention, this problem can be ruled out, that is, the multi-color color powder images carried by the main belt use electrostatic devices or The combination of electrostatic devices and heat transfers the image to the intermediate transfer element. The advantage of this method is to reduce the toner-toner shear effect, because in this part of the image, different colors The toners are stacked together. The drive of the main belt is best to use the drive device of the intermediate transfer element. By using viscous contact between the main belt and the intermediate transfer element, the main belt and the intermediate transfer element can be moved synchronously. The viscous contact between the belt and the image generation station can ensure that the main belt moves synchronously with the image generation station. The main belt is preferably passed through a guide roller, which is fixed in the middle The relative position of the conveying elements, which in turn forms a nip or contact area between them. The cleaning device for the main belt and the optional cooling device for cooling the main belt can be provided after contacting the intermediate transfer element. It can also be set to adjust The main belt tension device to ensure that the toner image is well placed at this place, and then change the quality of the multi-color toner image transferred from this place to the intermediate transfer element. It can also be included for controlling f (Notes on the back of Min reading and then fill out this page).

The rotary endless plane device is preferably a cylinder having a light-sensitive plane. The child transfer device includes a transfer roller located at the plane of the main belt relative to the child cylinder, or a discharge transfer device. When the transfer device is a drum, the contact angle between the main belt and the cylinder is less than 5 degrees. The angle is measured from the thin line of the rotary endless plane device, that is, almost tangential contact. However, when the transfer device is a discharge transfer device, the contact angle between the main belt and the cylinder is preferably more than 5 degrees, so the viscous contact between the main belt and the rotary endless plane device can ensure that The driving power is reliably transmitted from the main belt to the cylinder. The reliability of this power transmission can be further determined using the tension of the main belt.

Description of invention (10), polyethylene, polystyrene, and copolymers thereof, for example, styrene-acrylic resin, styrene-butadiene resin, acrylate, and methyl acrylic acid Salt resin, polyethylene gas resin, copolymerization (vinyl chloride-vinyl acetate) resin, ethylene butyl resin, polyvinyl alcohol resin, polyimide resin, polyimide resin, polyamide resin and polyhydric resin. Polyester resins are the most suitable because of the high brightness and abrasion resistance provided. Usually the glass of these resins temporarily exceeds 45 degrees Celsius, usually higher than 54 degrees Celsius. Other mixtures in the form of toner particles, such as colorants, usually have no effect on the temporary temperature of the glass. The volumetric resistance value of the resin is preferably 1013 ohm-cm. Appropriate toner composition is disclosed in European Patent Application No. Ep_A_001235, and EP-A-628883 and International Patent Applications w 94/27192, 94/271 91 and 94/29770 (Alfa-Gvitt NV). The most common toner composition has a temporary temperature of about 55 degrees Celsius and a melting point of 90 to 155 degrees Celsius. The use of a transfer belt instead of a rotary drum as an intermediate transfer element uses a larger contact area between the element and the main belt. The viscous contact between the two is improved, so that without increasing the pressure, a more reliable drive transmission is obtained from the intermediate transfer element to the main belt. Furthermore, the use of intermediate belts has better advantages than other devices such as transfer rollers. Half or a section of the transfer belt can be heated, while the other half is still cold. In this way, the temperature of the contact part between the transfer belt and the base layer can be higher than that of the contact point between the transfer belt and the main belt, so the transfer of the toner image is improved, and the chance of offset overlapping images is reduced . In order to produce a bright image, it is recommended to do this intermediate transfer element -13-This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 Gongchu :) I -------- approved clothing-- ---- 1T ------ ^ (Please read the precautions on the back first and then fill out this page) Printed by the Ministry of Economic Affairs, Central Bureau of Standards, Employee Consumer Cooperative A7 Printed by the Ministry of Economic Affairs, Central Bureau of Standards, Employee Cooperative Print 5. Description of the invention (11 may be flat. Especially if the roughness Ra of the plane is lower than 02 microns, very good results will be obtained. If a lattice image is to be produced, the roughness of the plane can be higher. Type of base layer Take the mesh type. The mesh cutting device, optionally together with the layer stacking device, can be placed downstream of the intermediate transfer element. In another embodiment, the mesh does not need to be cut into sheets, and It is wound and collected by the take-up drum. In another implementation, the base layer can also be a cut sheet layer or other suitably shaped objects. The present invention is particularly useful when printing base layers with significant thickness and rigidity. It has advantages. Compared with those printing devices that directly transfer toner images to the base layer electrostatically, it has more advantages, because the electrical conditions of the base layer are not so important. For example, the base layer does not need to be conditioned In order to control its humidity content within a specific range, and does not require a conditioned printer environment. These advantages significantly exceed those already disclosed printers, such as the aforementioned US Patent No. 5455668 ° can be used The range of the base layer is also increased at the same time, for example, including a base layer made of a synthetic material, a transparent tissue or an irregularly shaped material.

When the base layer is a mesh, the base layer can be in contact with the position sensing device between the first and second transfer elements. The signal output of the sensing device can be used to control the drive motors of individual intermediate transfer elements. To ensure that these intermediate transfer elements operate at the same speed. In a second alternative embodiment of the invention, the main belt and the intermediate transfer element may be constructed of one piece and the same element. The transfer element can be formed by the use of skin life 'and provide a device to guide the belt through a set of toner production stations' where most of the different toners are transferred to specific locations on the belt corresponding to each other, which is then formed on the belt Various toner images and the arrangement of the feeding device of the base layer can make the base layer travel along the path of the base layer and contact with the belt. In order to reduce the energy lost to the environment, we recommend that the device for heating the toner image on the transfer element preferably forms a heat exchange relationship with the device for cooling after the transfer element completes the transfer of the toner image. For example, a device for heating multiple color toner images on a transfer element includes a preheating drum and a preheating drum, where the two maintain a heat exchange relationship with each other. The heat exchange relationship can be made by forming each heating and cooling roller into a hollow structure, and introducing a heat exchange fluid, such as water, to make it flow between the two. In this way, the heat energy extracted from the cooling roller can be transferred to the heating roller and used to heat the toner image of the transfer element.

In order to prevent the color powder image of multiple colors from being transferred to the transfer element and transferred from the transfer element to the base layer, we recommend that the transfer element carries the image Flat, it is best not to contact any other components. Thus, unnecessary transfer or partial transfer from the transfer element can be avoided. Thus, when the transfer element is a belt, roller, or other guiding device, the plane in contact with the belt is opposite to the plane carrying the image, or at least the image is distributed to the belt and the image is transferred When printed on this base.

Description of the invention (16) The fixing method is such that the transfer belt 12 must be in contact with the toner image carrying belt 12 when the transfer belt 94 passes through the grounded guide roller 14. The transfer belt At the same time, 94 passes through a second heating guide roller 102. The heating roller 102 is driven by a driving motor 27. The driving power is then transmitted by the driving motor 27, and is transferred to the toner image in place through the transfer belt 94 The main belt 12 downstream of the production station also conveys the toner image at the production station itself. The main guide roller 14 and the intermediate transfer belt 94 are arranged corresponding to each other, thereby forming a nip or contact area therebetween , And the main belt 12 passes there. By viscous contact between the main belt and the intermediate transfer belt, the main belt and the intermediate transfer element can be moved synchronously. A paper web 28 is supplied by The drum 30 is unfolded, and through the printer 3, the mesh freely passes through the rotating cylinders 32 and 34 in the direction of arrow C, and enters a pair of mesh driving cylinders 36, which are driven by a pair of driving motors (in the figure (Not shown).

Description of the invention (17) Toner particles on the belt 12 and attracting them The plane of the intermediate transfer belt 94. The transfer discharge device typically holds it. The discharge coil is fixed at 7 cm on the seat body. The seat body surrounds the discharge coil and is also 7 cm away from the intermediate transfer belt. A typical transfer The discharge current is 3 microamps / cm of discharge width. The transfer discharge device 106 is also used to generate a strong adsorption force between the intermediate transfer belt 94 and the main belt 12, so that the main belt and the intermediate transfer belt 94 Simultaneously move together and force the toner particles to form a firm contact with the intermediate transfer belt 94. A mesh release discharge device 1 〇8 driven by alternating current is placed on the periphery of the transfer discharge device 106. Its role is to Eliminate the sparks generated when the intermediate transfer belt 94 leaves the main belt surface. After the printing of multiple color toner images printed by the employee cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, the intermediate transfer belt 94 passes through an infrared radiant heater 109, which will raise the temperature of the toner particles to 1 5 0 Celsius. The temperature is the most ideal temperature for transferring the image to the paper web 28. In this way, it can be ensured that the toner particles on the intermediate transfer belt 94 do not rapidly cool when they contact the guide roller, because the guide roller is also heated. By transferring the toner to the paper web 28, the temperature rises, and because the surface energy of the paper web is higher than the intermediate transfer belt 94, the toner can be transferred 100%. There is no need to remove excess toner particles remaining on the intermediate transfer belt. However, it is still possible to provide a cleaning device, such as a cleaning roller, to remove any residual toner particles on the intermediate transfer belt, which are generated during the startup or printing process of the printer. After the intermediate transfer belt 94 leaves the heated guide roller 102, JL ____ -20-this '.
