Large Format Flatbed Printer Nozzle Maintenance And Maintenance

- Feb 07, 2019-

The large format flatbed printer's nozzle consists of a number of tiny nozzles that are similar to dust particles. If dust, fine debris, etc. enter the nozzle, the nozzle will be clogged, and the nozzle panel will be easily stained by the ink, which will eventually lead to poor ink ejection. Therefore, the maintenance of the nozzle is very important. The following points should be achieved in routine maintenance: (1) Do not remove the nozzle from the main unit and place it separately, especially in high temperature and low humidity. If left for a long time, the moisture contained in the ink will gradually evaporate, and the dried ink will cause the nozzle to clog. If the nozzle is clogged, a cleaning operation should be performed. If the cleaning does not serve the purpose, replace the nozzle with a new one. (2) Avoid colliding the nozzle surface with fingers and tools to prevent nozzle surface damage or debris, oil, etc. from clogging the nozzle. Do not blow air to the nozzle, do not put sweat, oil, drugs (alcohol), etc. on the nozzle, causing changes in the composition and viscosity of the ink, causing the ink to clog. Do not wipe the nozzle surface with tissue paper, lens paper, cloth, etc. (3) It is best not to turn off the power while the printer is in the process of printing. The printer can be turned to the OFF LINE state, the power can be turned off when the nozzle is capped, and the plug is finally removed. Otherwise, for some models of printers, the printer cannot perform capping operations, and exposure of the nozzle to dry air can cause the ink to dry out. 1. Nozzle cleaning 1. Software cleaning: automatic cleaning by the maintenance function in the printer driver; 2. Ink cleaning: When the ink car is in the initial position, use a syringe with a hose to connect to the waste ink tube and extract about 5 ml. The ink does not cause the inner cylinder of the syringe to rebound, which may cause color mixing phenomenon in each nozzle. If the nozzle is not tightly sealed during the ink extraction process, the ink can be lightly moved by hand to ensure the nozzle and the nozzle protector. Good seal. After the ink is pumped, the software is cleaned. 3. Flushing and cleaning: remove the ink cart, remove the ink bag, connect the syringe with the cleaning liquid to the ink column of the nozzle, push and withdraw with appropriate pressure, and spray the complete thin wire vertically to the nozzle. 4, print cleaning: replace the ink with the nozzle phenomenon by using the "head cleaning agent", use the vector graphics software to print the color block of the color, to clear the nozzle blockage phenomenon, and then switch back to the original ink. 2. Maintenance of the nozzle If the nozzle is used for a long time, it is necessary to carry out professional maintenance methods and steps for the nozzle: 1. Remove the nozzle from the printer according to the correct method and clean the residual ink; 2. Use the nozzle cleaning agent Thoroughly clean the nozzle; 3. Inject special nozzle maintenance agent into each ink column of the nozzle;
