CCD screen printing machine, as a special printing equipment, has a different working principle from conventional inkjet printers. Regarding the question of whether and how to add ink to CCD screen printing machines, the following points need to be clarified:

　　1、 Does the CCD screen printing machine add ink

　　CCD screen printing machines do not directly add ink. Traditional screen printing machines use ink instead of ink, which is transferred to the substrate through the screen printing screen to achieve the printing effect. Therefore, the CCD screen printing machine does not involve the addition of ink during operation.

　　2、 If referring to ink management for similar devices (assuming similar inkjet printing equipment)

　　If the "CCD screen printing machine" in the question is misunderstood as a device similar to inkjet printing, the ink adding process may be similar to that of an inkjet printer, but the specific details may vary depending on the device model and brand. The following is a general ink adding step for reference:

　　Confirm equipment model: Firstly, it is necessary to confirm the specific model of the equipment, as the ink addition method may vary for different models of equipment.

　　Purchase compatible ink: According to the device model, purchase the officially recommended or compatible ink.

　　Prepare tools and materials: typically including gloves (to prevent ink from staining hands), tissues (to wipe off spilled ink), and possibly a screwdriver (some equipment may require disassembly of the casing).

　　Read the instruction manual: For detailed steps, it is best to refer to the instruction manual that comes with the device.

　　Open the ink tank: Follow the instructions in the manual or video tutorial to locate and open the ink tank.

　　Install or replace ink: Install the new ink correctly into the ink tank according to the instructions, paying attention to the direction and position of the ink to ensure a secure installation.

　　Close the ink tank: After installing the new ink, quickly close the ink tank door to ensure sealing.

　　Print test page: After completing the ink addition, it is recommended to print a test page to check if the print quality has returned to normal.

　　3、 Precautions

　　During the operation, gloves should be worn to avoid direct contact of ink with the skin.

　　Operate in a well ventilated environment to prevent discomfort caused by ink odor.

　　Avoid touching the internal circuits of the device to avoid damaging it.

　　If you encounter any problems, you should promptly contact the equipment manufacturer or professional maintenance personnel.

　　In summary, CCD screen printing machines do not directly add ink, but use ink for printing. If the problem refers to ink management similar to inkjet printing equipment, the ink adding steps may vary depending on the device model and brand, but generally follow the above steps.
