In fact, digital multifunctional machines using laser printing technology consume a large amount of resources during production and become major power consumers during use, with a power consumption of only one kilowatt, increasing the burden of carbon emissions. Experts believe that compared to the large amount of electricity consumed by laser technology during powder coating and fixing, inkjet equipment only requires weak electricity during the printing process, resulting in low product operating power. Therefore, inkjet equipment is more in line with the concept of energy conservation and emission reduction.

Environmental protection is not just about reducing carbon emissions!

The impact of printing equipment on the environment is not only reflected in carbon emissions, but also in dust pollution, waste material disposal, and other aspects:

Dust pollution. Laser printers can cause certain dust pollution. When the laser printer is working, it charges the photosensitive drum and immediately fills its body with positive charges. At this point, the printer converts the printed information into laser beam information, which is reflected by the reflective prism inside the printer to the photosensitive drum for exposure, and then the image is formed on the surface of the photosensitive drum. Then, the photosensitive drum will adsorb the toner particles in the toner cartridge, forming a toner image on the surface of the photosensitive drum.

Afterwards, the printing paper is filled with negative charges before entering the printer and coming into contact with the photosensitive drum. When the printing paper comes into contact with the photosensitive drum, the positively charged carbon powder image attracts the negative charges on the printing paper and adheres to it. After being heated by the thermal transfer unit, the outer ring of the carbon powder particles is adsorbed onto the paper fibers, ultimately forming the printed image. Finally, the printer will automatically remove the remaining toner on the photosensitive drum and correct the potential for the next cycle to begin.

During the entire process, the adsorption of carbon powder by the photosensitive drum, heating and fixing by the heat transfer unit, and removal of carbon powder by the photosensitive drum may all release the carbon powder into the air, causing pollution to the environment around the laser printer.

Therefore, we need to pay attention to the dust hazards of laser printers, avoid using laser printing products for a long time in a closed environment, strengthen health protection awareness, and avoid using inferior toner and toner cartridges.

In addition, in order to save so-called costs, many companies or individuals are willing to "pour powder" or "pour ink" and reuse consumables that have already passed away. Little do they know, whether it's at the beginning of powder filling or during the filling process, or during the use of secondary regenerated toner cartridges, non sealed consumable configurations are likely to cause environmental pollution.
