The daily maintenance of monochrome printing machine should not be ignored

Hefei Xingguang printing factory has a monochrome printing machine. After the maintenance and adjustment in the off-season are normal, it has not started printing for a long time. After that, it undertook to print a batch of two-color prints, most of which were flat. Because it was inked before printing without washing the car, there was a piece of ink about 2cm2 in the middle of the prints, which became lighter and lighter. After the printing speed was reduced, the ink color returned to normal. The two clamps separated and stretched the sample at a constant speed. It was found that although the ink on the ink transfer roller was uniform, one of the inking rollers was not inked, and the axial position was the same as that of the printed matter. Feel it with your hand. It feels smooth. It turns out that the engine oil drips on it. Because the car washing operation was too troublesome, the operator used the cleaning paste to clean the roller. There was no place where the manufacturer's after-sales personnel specially adjusted the ink that would not cause problems, and then used the cloth to clean it. It was found that the effect was the same as that of car washing

experience: when the printer is not working for a long time, it should be covered with cardboard or plastic film to prevent dust from falling on the roller and causing no inking. In addition, pay attention not to drop the oil on the roller during maintenance
