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 operation of the laser printer 100 includes several steps including charging, laser exposure, toner coating, transfer printing, and pressurization and heating. First, the negative charge is evenly spread on the entire photosensitive drum 26; then, receiving the printing data from the computer, and after the calculation of the internal processor 20, the laser element 22 uses laser light to print the image of the printed manuscript on the photosensitive drum 26. Draw it out to release most of the static electricity, leaving only the static electricity where the text or image is. That is to say, the part of the negative ch...

Abstract

The invention discloses a laser printer, which comprises a supporting roller, a heating roller and solid spices. The heating roller is arranged relative to the supporting roller, and the supporting roller and the heating roller rotate synchronously to jointly clamp and transport the paper carrying the toner, thereby fixing the toner on the paper. The solid fragrance is adjacent to the heating roller, so that the fragrance is sublimated by the heat of the heating roller to release the fragrance and attach the fragrance to the paper so that the paper is scented.

Printers are mainly classified into laser printers and inkjet printers. Laser printers are most praised for their high printing speed and excellent printing quality. In enterprises, laser printers are mostly used as group printers or departmental printing centers, which are completely based on performance, durability, and output requirements. Since laser printers meet these needs, they are extremely common in businesses. [0003] As far as laser printers are concerned, in the last step of printing, a heating device is used to fuse and fix the toner on the paper. [0004] However, the material of the heating device or the pungent smell produced by the toner itself is transferred to the ...
