Flatbed printing machine service life, is crucial to operators are used appropriately, and maintenance of printing machine printhead more important link in the machine after use, the maintenance of good or bad will directly affect the service life of the length and whether it can reduce the cost of the warranty costs. But in actual operation, operators often ignore digital printing printhead to maintain this link. To introduce below the flatbed printer printhead maintenance method.
Tablet printer nozzle consists of a small nozzle, inkjet hole, almost digital printing number of dust particles. Such as dust and small debris into the nozzle, the nozzle clogging, but also easy to dirty ink nozzle panel, eventually lead to undesirable phenomenon inkjet. Important thing is to keep in daily maintenance, should do the following:
(1) do not from the host, and a separate place, especially in high temperature and low humidity condition, shower nozzle. If you place a long time, ink moisture content will gradually evaporated, dry ink nozzle will cause obstruction. If there nozzle blockage, should be cleaning operations. If achieve the goal of clean, replace the nozzle.
(2) of the fingers and tools nozzle surface, to avoid a collision, to prevent the nozzle surface damage or debris, such as obstruction of oil nozzle. Don’t blow nozzle part, do not sweat, oil, drugs (alcohol) and other stains on the nozzle, cause the ink composition, viscosity changes, causing the ink solidification block. Do not use paper towels, lens paper, cloth and other wipe the nozzle surface.
(3) it is best not to in the process of plate printer to print. Flat-panel printers, can offline first, nozzle cap off the power before, remove the plug end. Otherwise, some models of flat-panel printers, flat-panel printers can’t perform operations cap, nozzle can lead to exposure to dry air in the ink was dry. If nozzle clogging, clean the nozzle. As the following:
First, nozzle cleaning
1, clean software: flat-panel printers, automatic cleaning maintenance function driver;
2, pumping ink: ink in initial position, connected to the power waste ink extraction about 5 ml of ink and instead of the inner cylinder rebound hose, this will result in color mixing nozzle, the phenomena of ink in the process of drying, due to digital printing nozzle caused by untight seal, you can jog nozzle and nozzle protection inks, to ensure good sealing.
3, suction clean out of the ink vehicle, take out the ink damper, water column connection with cleaning fluid hose nozzle needle and ink into the proper pressure, vertical full thread back to the suction nozzle.
4, print cleaning: the use of “clean” but not in the ink nozzle clogging phenomenon, the use of vector graphics software to print color piece, to eliminate the phenomenon of nozzle clogging and to exchange the original cartridges.
Second, the head maintenance
If the nozzle using idle for a long time, need a professional nozzle maintenance methods and procedures
1, according to the plate printer on the right course of action to remove the nozzle, and clean up the residual ink stains;
2, thorough cleaning, use cleaner nozzle;
3, nozzle ink nozzle column to a special care agent.
Above all is flatbed printer nozzle maintenance need to pay attention to place, the trouble to do more at ordinary times maintenance, to ensure the normal movement of the machine, the so-called sharping knife doesn’t miss your job.
