What are the reasons for the curved fonts printed by laser printers?
What is the reason for the curvature of the font printed by the laser coder? If the curvature is small, if you don't pay attention, it is generally not easy to find, especially in the case of large fonts. This requires the user of the machine to pay more attention, and to do the necessary inspection or random inspection after Leadtech Coding. Because if this phenomenon is allowed to continue, the laser coder will definitely have a big problem, especially the problem of the galvanometer part of the print head.
The direct cause of the font bending is the inaccurate positioning of the galvanometer and the jitter. The deep-seated reasons for the inaccurate positioning of the galvanometer and the jitter are as follows:
1. The interference of the galvanometer signal, such as the signal ground of the signal line and the ground are not connected; there is interference between the signal line and the Q drive RF line, this interference can be checked by turning off the Q drive; the signal line is damaged, such as the shielding layer damage, etc.
2. There is a problem with the galvanometer itself, the potentiometer of the galvanometer, or the capacitor or other components are broken or the value has changed: there is a problem with the motor; the motor and the motor frame are not insulated.
3. The problem of the marking card is mainly due to a problem with the DA card, the conversion of the DA card cannot be performed, or a problem with the large card.
4. Computer problems, the software is not installed, the driver is not updated, the driver is not installed completely, and there is a virus in the computer.
The above are the reasons for the bending of the fonts printed by the laser coder summarized by science and technology. If you want to know more technical problems, please call us!
