Description

Technical Field

[0001] The invention relates to the technical field of printers, and more particularly to a testing device for a laser printer heating component. Background Art

[0002] The heating component of a laser printer, also called a fuser, mainly includes a heating roller and a pressure roller. Its function is to pass the transferred print medium through the narrow gap between the heating roller and the pressure roller of the heating component. Under high temperature and pressure, the toner that has been transferred to the paper is melted and pressed into the paper fiber, thus forming a clear and lasting image and text.

[0003] The heating roller is responsible for providing high temperature to melt the toner; the pressure roller applies a certain amount of pressure to ensure that the toner can be evenly embedded in the paper; the working performance of the fuser directly affects the printing quality and the stability of the printer. If the fuser fails, it may cause problems such as blurred printed images, toner shedding, and paper curling. In daily use, you should pay attention to choosing the right paper type and avoid using paper that is too thick or too thin, or too smooth or rough on the surface, to reduce damage to the fuser. At the same time, regularly cleaning the residual toner and debris on the fuser will also help extend its service life;

[0004] In the process of producing laser printers, it is very necessary to test the heating component. The performance of the heating component directly affects the printer's fixing effect and printing quality. Through testing, it can be ensured that the heating component can reach the predetermined temperature and the temperature distribution is uniform, so as to ensure that the toner can be fully melted and fixed on the paper, avoiding problems such as blurred printed images and toner falling off. The test can also detect the heating component's heating speed, temperature stability and performance under different working conditions; this helps to discover possible faults or performance defects in advance, improve the overall quality and reliability of the printer, and reduce after-sales maintenance costs.

[0005] In order to test the performance and effect of the fuser, the existing laser printer heating component testing device usually installs the fuser in the printer, and then starts the printer to perform the test. During the test, the printing paper needs to be placed in the paper feed channel manually. In addition, the fuser needs to be tested many times, so the staff needs to continuously place the printing paper in the paper feed channel of the printer, which makes the test more troublesome, inconvenient, wastes printing paper, and it is difficult to intuitively observe the working status of the fuser. In view of this, we propose a laser printer heating component testing device. Summary of the invention
