The head of the uv flatbed printer consists of many tiny nozzles, inkjet holes, and dust particles, which are about the same size. If dust, fine debris, etc., are introduced into the nozzle, the nozzle will be clogged, and it will also be easy to stain the nozzle panel with ink, which can eventually lead to a bad ink jet phenomenon. So nozzle maintenance is vital.

In the daily maintenance should do the following.
(1) Do not remove the nozzle from the host and placed separately, especially in the high temperature and low-humidity environments. If left for a long time, the water contained in the ink will gradually evaporate, and dry ink will lead to nozzle blockage. If the nozzle has become clogged, cleaning operations should be carried out. If the cleaning does not achieve the purpose, then replace the new nozzle.
(2) Avoid using fingers and tools to collide with the nozzle surface to prevent damage to the nozzle surface or debris, oil, and other blockages of the nozzle. Do not blow into the nozzle area, do not sweat, oil, drugs (alcohol), etc., on the nozzle, as this can cause changes in the composition of the ink, viscosity, and cause the ink to solidify and block. Do not wipe the nozzle surface with tissue, lens paper, cloth, etc.
(3) It is best not to turn off the power at the printer during the printing process. First, turn the printer to the OFF LINE state, remove the nozzle cap before turning off the power, and finally unplug it. Otherwise, for some models of printers, the printer can not perform the capping operation, and the nozzle exposure to dry air will cause the ink to dry out.

After pumping ink and then software cleaning.
3, injection and extraction cleaning: remove the ink cartridge, pull down the ink bladder, hose the syringe with cleaning fluid and nozzle to the appropriate pressure to push the injection, back to pumping, to the nozzle, vertical spray out the complete thin line.
4, print cleaning: “printhead cleaner” instead of the phenomenon of clogging the nozzle ink, use vector graphics software to print the color block, to the nozzle clogging phenomenon, and re-exchange back to the original ink.
