Why waste ink is produced when using a big size sublimation printer?

Waste ink is generated during the use of  the big size sublimation printer. Why? Let's go and have a brief look.

The wide-format sublimation printer generates a large amount of waste ink during the printing process, mainly focusing on the inkjet printer using the split design. The main reason is that the split structure is adopted. 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 quick-drying type. The long-term use of the printer and the dry weather will cause the residual ink on the nozzle to condense to cause disconnection during printing.

In order to solve problems such as print breaks and unclear writing, all 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 “nozzle protection seat” sealing function is used to implement a short-term seal to prevent the ink head of the print head from clogging the print head.

For split-type models that are prone to breakage, the manufacturer has adopted a more comprehensive printhead cleaning and dredging system, that is, a pump attachment with a special cleaning printhead under the "nozzle protection seat", which periodically extracts the ink from the ink cartridge. Let each ink pass through the nozzle hole, and finally spray from the nozzle to achieve the purpose of clearing the pipeline to ensure smooth flow. The inks of various colors sprayed from the nozzle are finally mixed together to become waste ink, which is to clean the print head. In the whole process, many people refer to it as "shampoo". The waste ink generated by “shampooing” has to be stored in a place, so the manufacturer set up a separate plate in the lower part of the printer, called the waste ink tank (also called waste ink tray), and the waste ink of “washing the head” passes through the pipeline. Go directly to the waste ink tank below the wide format inkjet printer.

The integrated inkjet printer replaces the ink cartridge and replaces the printhead, 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.
