Embodiment Construction

[0010] Please refer to FIG. 1, which shows a block diagram of a laser printer according to a preferred embodiment of the present invention. The laser printer 100 of this embodiment includes a processor 20, a laser element 22, a photosensitive drum 26, a toner cartridge 24, a supporting roller 80, a fusing roller 90, and a solid fragrance 70. The printing action of the laser printer 100 includes several steps such as charging, laser sensitization, coating of toner, transfer, and pressure and heating. First, the negative charge is evenly spread on the entire photosensitive drum 26; then, the printing data from the computer is received, and after the calculation of the internal processor 20, the laser element 22 uses a laser to print the image of the manuscript on the photosensitive drum 26 Draw it out and release most of the static electricity, leaving only the static electricity at the location of the text or image. In other words, the negative charge of the part to be printed in b...

Printers are mainly divided into laser printers and inkjet printers. Laser printers are best known for their high printing speed and excellent printing quality. In enterprises, laser printers are mostly used as group printers, or as departmental printing centers, based solely on performance, durability, and output requirements. Because laser printers can meet these needs, they are extremely common in enterprises. [0003] As far as laser printers are concerned, in the last step of printing, a heating device is used to melt and fix the toner on the paper. [0004] However, the pungent smell produced by the heating device material or the toner itself is transferred to the printed page, ma...
