Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine for quickly replacing a toner cartridge. Background Technique

[0002] A printing machine is a machine for printing characters and images. Modern printing machines generally consist of mechanisms such as plate loading, inking, printing, and paper feeding (including folding). Its working principle is: first, the characters and images to be printed are made into printing plates and installed on the printing machine, and then ink is applied to the areas with characters and images on the printing plate manually or by the printing machine, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wooden boards, glass, and ceramics), so as to reproduce the same printed matter as the printing plate. The invention and development of printing machines play an important role in the spread of human civilization and culture.

[0003] After the toner in the laser printing machine is used up, the toner cartridge needs to be taken out for replacement or toner addition. After opening the flip cover, the toner cartridge is directly taken out for replacement. The toner cartridge is directly inserted in the corresponding position, but the toner cartridge lacks positioning during replacement. There may be a slight deviation after the toner cartridge is installed, and the printing position will also deviate. For this reason, we propose a printing machine for quickly replacing a toner cartridge. Content of the Utility Model
