Abstract: Inkjet printers are industrial machinery and equipment that mark products in a non-contact manner. With the development of technology, handheld inkjet printers can be operated by hand, are compact and portable, and are especially suitable for large items or Printing on items that are difficult to move. When using a handheld inkjet printer, you must first test whether the printing effect is normal. After confirming that it is normal, move the nozzle to the position that needs to be printed, and use downward printing to print. When using a handheld inkjet printer, pay attention to proper grounding to avoid contamination with ink, solvents and other consumables, and also pay attention to the maintenance of the inkjet printer. Let’s learn how to use a handheld inkjet printer. 1. What is a handheld inkjet printer?

A handheld inkjet printer, also known as a portable inkjet printer, is a printing device that can be carried around and is usually used to print trademark patterns, Chinese and English Fonts, numbers, barcodes, QR codes. Handheld inkjet printers are characterized by being lightweight, compact, functional and highly informatized. They are mainly used to inkjet large items or items that are difficult to move. So how to use a handheld inkjet printer?

2. How to use a handheld inkjet printer

The principle of a handheld inkjet printer relies on electrostatic deflection. When used, it can usually be held by hand for printing. The specific steps are as follows: :

1. First spray some cleaning fluid on the surface of the nozzle. After one minute, gently squeeze the ink bag to let the ink flow out of the nozzle.

2. Place a piece of white paper in front of the nozzle, press the strong spray button and move the paper in front of the nozzle. This step is to test the printing effect to see if all 128 holes are filled with ink and there is no white paper. The line indicates that it can be used normally.

3. If a white line appears in the middle of the spray, squeeze the ink bag again and repeat the previous work until the printing effect is normal before printing again.

4. After confirming the printing effect, import the pattern to be printed into the machine through a USB flash drive, then move the nozzle to the position that needs to be printed, and use downward printing to print.

5. After printing, tighten the handle screw and fix the nozzle. Note that if you change the direction of the nozzle before loosening the handle screw, it will easily cause the nozzle to be loose and affect the printing quality.

3. Precautions for using handheld inkjet printers

Handheld inkjet printers are easy to use and have a wide range of uses, but you must also pay attention to safe use during use to avoid accidents:

1. The handheld inkjet printer relies on static electricity to deflect, so it must be confirmed to be well grounded before use. Otherwise, it may cause problems such as poor printing quality and poor ink dot splitting. In severe cases, static electricity accumulates to a certain extent. Sparks may cause a fire.

2. Water cannot be mixed into the ink, solvent, cleaning fluid and other consumables of the handheld inkjet printer, because the ink dots need to be printed accurately, and the ink of the inkjet printer is very sensitive to water.

3. The ink and solvent of the inkjet printer are corrosive. During use, these substances should be avoided from contaminating the skin, eyes, nose and other parts. If accidentally contacted, you need to quickly use a large amount of Rinse with clean water for a quarter of an hour. If you still feel unwell, seek medical attention.

4. The handheld inkjet printer needs to be lubricated every month of use. Pay attention to keeping the handheld inkjet printer clean after each use so that the machine can be kept in good condition.
