Sublimation Ink Cartridge (ink tanks) is key ink supply component in inkjet printing systems. Their primary function is to store and maintain a stable supply of ink. Ensuring continuous printhead operation during the printing process. They can be divided into primary and secondary ink cartridges. The primary cartridge (ink tank) is used to store and add ink. While the secondary cartridge (secondary) supplies ink to the printhead. As an ink transfer station, ink cartridges play a crucial role in ensuring print quality and device stability.
Functions of Ink Cartridges
Stable Ink Supply: They store an appropriate amount of ink, ensuring a continuous and stable ink supply to the printhead during printing. Preventing ink shortages caused by sudden demand.
Filtration and Protection: High-quality ink cartridges often feature internal filters or specialized flow channels to prevent large particles from entering the printhead. Thereby reducing the risk of printhead clogging.
Negative Pressure Control: Many ink cartridges are equipped with a negative pressure function. By balancing air and hydraulic pressure, this ensures a uniform ink output during printing. Preventing problems such as leaks and overflows. Extended Lifespan: High-quality ink cartridges can reduce the workload on the printhead. Indirectly extending its lifespan and reducing maintenance frequency and costs.
Use Scenario
Photo printers: They often use transparent plastic ink cartridges for easy inspection and replacement.
UV DTF printers: They often use metal negative pressure ink cartridges, suitable for long-term continuous printing.
Wide format dye sublimation printer: Ink cartridge design prioritizes capacity and ink flow to ensure color output at high production speeds.
Precautions
Ink cartridges are consumable parts and require special attention during use:
Replace them regularly: The sponge in the secondary ink cartridge, in particular, loses its absorbency after long-term use, affecting ink supply.
Avoid frequent ink refills without changing the cartridge: This can easily lead to impurities accumulating in the filter, increasing the risk of clogging.
Do not disassemble the printer yourself if an alarm is heard, ink is out of service, or ink is not ejected, contact a qualified technician to avoid damage caused by disassembly.
