What should I pay attention to when using the ribbon printer?
1) Do not use inferior printer ribbon, but use inferior ribbon box and ribbon. In the printing process, because the box cover of inferior ribbon is not tightly combined with the box body, it is easy to cause the driven gear to deviate from its original position, and the driven gear is not tightly engaged with the main gear, which makes the ribbon loose. According to Lin Shi of Chengdu, due to the poor quality of the used ribbon, the ribbon ink will enter the needle seam of the printing head along the guide hole of the printing needle and solidify, resulting in an increase in the needle resistance of the printing head, which will easily cause needle breakage or crush the parallel slot of the printing needle, and even more seriously, burn the printing needle driver chip or ribbon motor and driver chip.
