In spring and winter, UV flatbed printer will always encounter a variety of problems during use, although details vary, but most are associated with cold and wet. Next, summarize a few notes on these phenomenons, hope these can be helpful on the maintenance of UV flatbed printer’s printhead.
1). In general, please do not put UV flatbed printer on the ground, especially carpeted floor, because it is easy to contain foreign matter or dust flew inside the machine. In the winter, indoor work environment is cold and dry, please preferably use a large and thick cloth to cover on the printer, because the printhead is inside of the printer, and if we can guarantee no much cold air go into the inner space of the printer, it will prevent the UV ink droplets on nozzles from solidification, or it will be easy to clog printhead, leading to decrease print quality. In addition, UV flatbed printer itself working mode determines the machine must be placed on the horizontal plane. Tilted way of working will not only affect print quality, slow down working speed of printhead, but also damage the internal mechanical structure.
2). In winter and spring, please boot once a week at least. When booting, the printer machine need to preheat and it will clean printhead automatically (usually boot cleaning consumes small amount of inks). It can discharge original ink droplets attached on the printhead, which could avoid printhead clog because of long-time stay of inks. Meanwhile, place the nozzles used one time and see if there is the phenomenon of printing missing lines.(the phenomenon of missing lines is usually because of printhead clog).
3). We can see that there is a relatively smooth gavelock cross on UV flatbed printer when open the top cover (this operation must be carried out in the off state). In the industry, this gavelock is called guide bar, it is the working guid rail of UV flatbed printer. It has lubricant on guide bar, which makes the printing work faster and more precise. However, the cold winter weather is easy to make lubricating oil solidified, and plus the lack of routine maintenance (such as, always opening the top cover when printer works,which leads dust constantly invade guide bar.), and these are likely to make the carriage appear abnormal. At this point, we need to drop a few drops of precision lubricating oil onto the guide bar, and try to clear the filth original left on the guide bar.
