Why should the printer be grounded during installation?

The working principle of the printer is based on electrostatic deflection, so it must be grounded. If there is no grounding or poor grounding, the useful signal constitutes a harmful electromagnetic noise or signal, which can constitute a poorly split ink dot, which constitutes the instability of the printing and affects the normal use of the inkjet printer.

Shielding electromagnetic interference means grounding. Positive electromagnetic interference refers to electromagnetic noise or signals that pose a hazard to a useful signal. There are two types of internal electromagnetic disturbances that can occur in the system and electromagnetic disturbances that are external to the system.

The anti-interference grounding method adds a metal protective layer outside the protected device or circuit, so that the electromagnetic wave forms a current in the metal layer, and then grounds the protective layer to vent the shielding current. In fact, it is for common mode disturbance (that is, the electromagnetic harmonic between the phase line/the neutral line and the ground line), and the outstanding grounding of the specification can effectively disturb the common mode, that is, shield electromagnetic interference.

The origin of the industrial scene is multi-channel. For different projects and different sites, there should be different disposal methods. Shielding and grounding are a technical part of the operation of industrial control system developers. Therefore, the manual of the electrical equipment emphasizes the reason why the equipment has an excellent grounding. Proper planning and use of anti-interference grounding is not only related to the safe and stable operation of the system, excellent interference, but also an important symbol of the maturity of industrial project developers.

The friend who knows the printer may have experienced the difference between the ungrounded and grounded wire of the small character printer in the actual installation process of the printer. In fact, in actual production, not only the small character printer needs to be grounded. Other marking equipment such as high-resolution inkjet printers also need to strictly follow the instructions for the external grounding wire, thus ensuring the stable operation of the printer.
