Thermal inkjet printer, like this A4 mini document mobile Bluetooth and wireless compatible inkjet printer with Android and PC support sometimes referred to as bubble jet printers, use thermal energy or electricity to heat ink and apply it to a medium. They can provide a low-cost option for high-speed printing, and can print on a variety of surfaces.     

Process

Depending on the printer, 300 to 600 tiny nozzles heat up the ink in the cartridge, expanding it in a bubble. The ink from this bubble is pushed through a nozzle onto the paper. Eventually, the bubble collapses, or pops, and the air vacuum sucks more ink into the nozzles. Each of the nozzles can apply ink simultaneously, from both black and white or color cartridges.                                                                    

Warning

Make sure that the levels of ink in the cartridge don't get too low. As the nozzles heat up, the ink itself acts as a coolant, so if there's little or no ink left in the cartridge, the nozzles may become too hot and damage your printer. Alternatively, if the ink in a nozzle dries and hardens because of a depleted ink supply, it can prevent the nozzles from issuing more ink on subsequent print jobs. However, you can clean the nozzles with rubbing alcohol.

How to prevent Bluetooth and wireless Inkjet paper from smearing

1 Use high-quality, quick-drying and smear-resistant ink, as well as the correct paper for your project. Quick-drying paper can help keep the ink from smearing, too.

2 Allow a single printout to dry in the tray before touching it.

3 Remove the printout from the printer as soon as it finishes if it's a multipage print job. Place it printed side up so it can air-dry. Hang dual-sided printouts with a clothespin and leave them to dry.

4 Lightly sand vellum or heavy paper types with superfine sandpaper. The resulting rougher texture helps keep the ink from smearing over the slick surface of the paper.

5 Use an art sealant meant for paper and ink. Spray it lightly across the paper and allow it to dry.

One of the most popular categories of industrial inkjet printers available today, thermal inkjet (TIJ) printers are compact, cost-effective machines that are built to create high-resolution codes on a variety of substrates. Coming in a host of makes and models that emphasize different advantages (e.g., mobility, substrate specialization, print height, etc.), TIJ printers can meet the needs of the modern production line without compromising quality. However, depending on the unique needs of your enterprise, there is a possibility that an alternative machine, such as a continuous inkjet (CIJ) printer or high-resolution case coding printer, may be better suited.

To provide clarification on the subject, this article will detail the basics of the question, “How does thermal inkjet printing work?” as well as profile what benefits arise from the “drop ejection” printing process used by these machines. With this information, you should be able to determine which of these devices is right for you.

How Ddoes Thermal inkjet mobile printer work?

As opposed to the replenishable tanks used by CIJ machines, TIJ printers use a system of replaceable cartridges for ink delivery. Through a process called “drop ejection,”  TIJ models propel the ink from these cartridges and onto the desired substrate via these 4 steps: 

Heat the ink: To start the process, the ink is delivered by the cartridge to a firing chamber where electronic resistors heat it at a rate of 1,800,032°F / 1,000,000°C per second.

Generate a bubble: Once the heat from the resistors causes the ink to reach a temperature of 644°F / 340°C, the ink is vaporized and generates a bubble. 

Propel the ink: As the bubble expands, the ink droplet is propelled from the chamber and out of the nozzle. 

Collapse the bubble: Once the droplet breaks away from the nozzle and onto the substrate, the bubble it was propelled by collapses. This creates a vacuum effect that pulls more ink into the chamber, causing the entire process to repeat.

Benefits of the Thermal inkjet mobile printer process

As a result of the drop ejection process outlined above, TIJ printers provide the following benefits: 

Low Maintenance/High Dependability

With the ink cartridge system utilized by TIJ printers, printhead services (which are a significant maintenance focus for other machines) are unnecessary. If there is a problem, simply switching out the ink cartridge for another often fixes the issue easily and within seconds. 

The four-step thermal inkjet printing process is far simpler than that of a continuous inkjet printer, which operates using ink-filled tanks, pressurizers, and piezoelectric print heads. Accordingly, TIJ machines can create high print quality for years without maintenance, while CIJ printers require regular expert care for optimal performance.

Along with the convenience of foregoing maintenance with Thermal inkjet mobile printer is a lower overall cost of ownership as well.
