Sometime, we will get the feedback from our customer,  why the printing characters uneven edges after printing?  There are 4 reason:

Point 1: Due to the incorrect position of the paper pressure lever, the paper pressure lever is in the paper release position.

Point 2: After the ribbon core is replaced, the ribbon cannot move flexibly, which will cause the carriage to be blocked during printing.

Point 3: The position of the printing paper is not suitable, which causes abnormal paper feeding.

Point 4: The gap between the paper feed slot and the paper feed roller is not adjusted properly. The paper cannot be fed evenly, which causes the characters to align when printing.
