Thermal Inkjet Technology

Thermal inkjet printers are the most common type of inkjet printers found in homes and offices. This technology uses a heating element to create small vapour bubbles inside the ink cartridge, leading to the ejection of ink droplets onto the paper. Here’s how it works:

Ink Cartridges: Thermal inkjet printers use small ink cartridges that contain one or more ink reservoirs. Each reservoir holds a specific colour of ink, such as cyan, magenta, yellow, and black (CMYK) inks.

Heating Element: Each ink chamber has a tiny heating element (usually a resistor) located close to the ink ejection nozzles. When the printer receives the print command, an electric current is passed through the heating element, rapidly heating the ink in the vicinity of the nozzle.

Bubble Formation: The heat causes the ink to vaporize, creating a small bubble in the ink chamber. This bubble forces a droplet of ink out of the nozzle and onto the paper.

Print Head: The ink cartridges contain built-in print heads that consist of multiple nozzles. These print heads move back and forth across the paper during printing, depositing ink droplets in precise patterns to form the desired image or text.

Thermal inkjet printers are known for their affordability, compact size, and ability to produce high-quality prints for everyday use. However, they may require more frequent replacement of ink cartridges, especially in high-volume printing environments.
