Why does the ink sublimation printer produce waste ink when it is used?

ink sublimation printerThe situation in which the ink sublimation printer generates a large amount of waste ink during the printing process is mainly concentrated on an inkjet printer using a split design. The main reason is that the printer uses a split structure. Since only the ink cartridge needs to be replaced, the joint between the print head and the ink cartridge is easy to enter the air, and the air entering from the print head can easily “support” the hole which is thinner than the hair thread, so that the ink cannot be unblocked, resulting in printing. Broken line phenomenon. Printing after a broken line will cause the text to be missing, the picture to have horizontal stripes and severe white lines. At the same time, in order to meet the needs of high-speed printing, the current inks are all fast-drying type. The long-term use of the ink sublimation printer and the drying of the air, etc., cause the residual ink on the nozzle to condense and cause the disconnection in the printing.

ink sublimation printerIn order to solve problems such as print breaks and unclear writing, all sublimation inkjet printers are equipped with a hardware system for ink cleaning and nozzle maintenance on the far right side of the machine. The inside of the printer is equipped with a rubber-made rubber scraper, which scrapes off the dirt attached to the nozzle surface with a rubber scraper. At the same time, after the printer stops printing, the ink cart automatically returns to the “nozzle protection seat”, and the sealing function of the “nozzle protection seat” is used to implement a short-term sealing to prevent the ink dryness of the nozzle from clogging the print head.

For split-type models that are prone to wire breakage, manufacturers have adopted a more comprehensive printhead cleaning and dredging system. That is, under the “nozzle protection seat”, there is a pump accessory for cleaning the print head. By periodically extracting the ink in the ink cartridge, each ink passes through the nozzle hole, and finally the nozzle is sprayed out to achieve the purpose of unblocking the pipeline. These inks of various colors ejected from the nozzles are finally mixed together to become waste ink. This is the whole process of cleaning the print head, which many people refer to as “shampoo”. The waste ink generated by the “shampoo” has to be stored in a place, so the manufacturer set up a separate plate in the lower part of the wide format sublimation printer, called the waste ink tank (also called waste ink tray). The waste ink of the “shamp” is directly piped into the waste ink tank below the printer.

The integrated sublimation printer replaces the ink cartridge and replaces the nozzle, so there is no pump attachment and there is no ink cleaning. It produces very little waste ink. The waste ink tank is under the “nozzle protection seat”. The residual ink scraped by the rubber scraper in the waste ink tank will be tied into the waste ink tank over time. The split type waste ink is large in volume, and the volume of the waste ink tank is also large. At the same time, a cotton felt is placed in the waste ink tank to adsorb the waste ink.

The sublimation printer starts to break the ink when it prints a few centimeters. Why?

sublimation printerWhat is the reason and solution for the sublimation printer to start to break the ink after printing a few centimeters?

This may be caused by air in the printhead. You can connect the ink column with a syringe and a silicone tube, pour the print head, suck the air out of the print head, and try to print it.

There are many reasons for the air in the wide format printer print head, which may be caused by air leakage in the ink bag, ink tube, ink cartridge, etc., and the tight contact of the ink path may cause air leakage. Before drawing the picture, make sure that the ink cartridge cover is sealed and the ink tube ink bag is not leaking. The connection between the ink tube and the ink cartridge is good, the connection between the ink bag and the ink tube is good, and the connection between the ink bag and the ink column of the print head is well sealed.

sublimation printerThe print head also has a leak. Generally, there is no such thing as a new print head. If the print head that has been used for a long time is not in place due to normal maintenance and the use is not correct, air leakage may occur. The specific performance is the internal ink splicing and the side leakage outside the nozzle, which can be used after maintenance.

The printhead is a precision part of a digital sublimation printer. In daily use, it is necessary to develop good habits and regular maintenance, so as to ensure the printing effect of the print head and extend the service life of the printer print head.

For those who are engaged in the advertising inkjet industry, the wide-format sublimation printer is no stranger. It is a large format printer with outstanding print results. However, if the installation is not in place, it will not meet the needs of use. Therefore, pay attention to every detail when installing the sublimation printer, which can effectively ensure that the device is running in good condition.

Be sure to install the rack and main unit.

In order to prevent the sloshing after the installation of the dye sublimation equipment, it is necessary to pay attention to the installation of each accessory in the installation. In particular, it is necessary to fix the relevant screws to ensure the printing effect of the device. In addition, when installing the rack and the main unit, you need to read the safety instructions in detail to make the safety work more in place.

Make connections and installations for ink cartridges, ink cartridges, ink tubes, and printheads.

sublimation printerSince this design has a lot of installation work, it needs to be executed according to the installation instructions or the instructions of the professional installer. In particular, the safe operation of the ink sublimation printer print head must be done in place, otherwise it will affect the printing effect. In addition, when installing a line problem, it is inevitable that you will encounter an inaccurate situation. Don’t try it yourself. Ask a professional person to guide or ask the manufacturer for the wiring diagram to ensure the installation is smooth. Of course, after the line installation and connection is completed, the staff needs to check and check several times to ensure that there is no problem.

It is very important to do the testing work.

In general, after the ink cartridge is installed, the entire installation work is nearing completion. At this time, the staff member needs to check whether the relevant ink supply line is connected properly. First add ink to the ink cartridge, do not overfill, and then turn on the ink pump to detect the ink. If there is no flashing, etc., it means that the installation is successful and can be used normally.

In addition, when installing a wide format sublimation printer, the staff also needs to provide a good installation environment to ensure a smoother installation.

It’s any printer that works by propelling droplets of ink, and the most common type of printer for home use. If you print from your computer, smartphone, or digital camera, you probably have an inkjet printer. Most large format inkjet printers allow color printing of photos and images, as well as black and white documents.

How Does an Inkjet Printer Work?
An inkjet printer creates an image by firing tiny droplets of ink, hence the inkjet definition. The print head moves back and forth as the paper is fed through a set of rollers. The complete image is built up from many small dots, a bit like the pixels on a TV or phone screen.

The quality of an image is determined by the number of dots per inch (DPI), and the range of colors possible. A few different colors of ink can be combined to produce virtually any color. Yellow, red, and cyan ink are the colors most commonly used. These can be combined to make black, although it’s usually more economical if a separate black ink is used. Each color may be contained in a separately replaceable cartridge or they may all be contained in a single cartridge.

A number of different technologies may be used to propel ink onto the paper. Most consumer printers use the thermal Drop-on-demand (DOD) method. In this process, ink is pumped from a cartridge to a tiny reservoir sitting directly behind a nozzle. A small electric heating element is located in the reservoir. When a pulse of electric current is passed through this element, the solvent in the ink vaporizes, causing an increase in pressure, which propels a drop of ink out of the nozzle. The bubble of vapor then condenses, contracting and drawing some more ink into the reservoir.

Some consumer wide format printers, as well as most industrial printers, use a piezoelectric material, instead of a heater. In these devices, a piezoelectric diaphragm, similar to a small speaker, sits at the back of the ink reservoir, opposite the nozzle.

The print head contains the nozzle, reservoir, and heater or piezoelectric. In many consumer printers, the print head is part of a disposable ink cartridge, meaning it’s replaced whenever new ink is required. In many more expensive printers, a fixed head is used, which is not replaced with the ink cartridges.

Other technologies are used in large scale commercial inkjet printers and other industrial devices. These often use a combination of ultrasonic vibration and electrical charge to propel and direct ink droplets in a continuous spray. Such printers may be much faster and use a greater variety of inks and dyes, including those which are solvent-based and ultraviolet curing. This can result in more durable and waterproof prints than can be achieved with consumer printers.

IIf you do digital pritning business, you must buy a large format printer. This is not a simple purchase. It is a hard decision made more complex by the fact that these printers are a business investment for a long run.The principal considerations in the selection process include whether you will go for a color printer or a mono one, speed and performance, costs and quality of image. Other than these four important factors, you should also consider ease of use, product options, environmental concerns, floor space and security.Color or monoThis depends on the customer demand. To determine which kind of printer you will buy, find out the maximum number of print jobs you will do in a one of these two categories.

If you regularly print posters, presentations and technical documents, buy a color wide format printer. However, if you do not frequently print in color, but is associated with an industry which prefers their work to be done at speed, do go for a mono or a black and white one.Another factor to consider is the robustness of print. In case your prints are exposed to the outside weather, there is a need to make these prints waterproof. Mono printers do a much better job in such cases. If you buy a color printer, you should also consider buying color toner and pigment ink.CostsDo understand that a large format printer is an investment.

Although it is granted that the price plays an important part in the decision, it should not be the most important of all. Smart buying means purchasing a printer whose supplies are already compatible with your older model or with the economically priced consumables in the market. Installing new software may cost you precious money. Running expenses are also important. Hidden costs are a menace to the profitability of any print company. You should not have to print the same thing a number of times to get the optimal quality of print.Speed and performanceYou should not spend lots of money on an expensive printer if middle priced ones satisfy your requirements.

Consider the processing time. The printer processes the files prior to printing them. To know whether a printer can print your kind of job, check the internal memory. Run bigger files prior to shelling out the money. Warm-up time is also important.Quality of image and ease of useDotted and fine lines must be clearly printed. Information must not be lost. If this happens, then the consequences can be catastrophic- an example being leaving out a dotted line in an electrical wiring diagram. The wide inkjet printer must be easy to use so that productive work can be done.
