The magnetic magnetic spectrum is the most important visible component of the single grouping of the hpcanon series of magnetic carbon powder structures in the selenium drums, with varying degrees of influence on the blackness, shadows, bottom ash, cyclical white bars and page production of the print. The main structure consists of magnetic shampoo tubes, magnetic cores, magnetic core conductors and magnetic core axles, which are coated with a graphite material to increase friction between magnetic shampoo drums and carbon powder and chalk. Magnetic surface coatings are thin, magnetic core materials are thin and easily damaged. Therefore, great care must be taken in the preservation, transport and assembly process so that the magnetic pads are not placed around the metal material so that they are attracted by magnetic force to the metal material leading to coating damage, nor can the chemical clean magnets be used to avoid direct hand contact with the magnetic coatings, as the sweatings on the hands, the degenerative oils leave clear marks on the coating and visible hand prints appear in the print. The main technical features of the magnetic tape are as follows:
A. A good surface magnetic field strength with a magnetic field strength of 650 ~ 1200 gs on the general magnetic surface, with different requirements for different printers, but generally higher or lower than the printer's scope of application, leading to a decrease in blackness, e. G. A surface magnetic field strength of 7115 magnetic field strength below 1100 gs would result in print bottom ash
B. Good co-accuracy, resulting from changes in the distance of the surface of the tube from the centre of the magnetometer and from the distance between it and the sensory drums due to the excessive print jump caused by poor accuracy of the magnetium as a whole. A non-working surface test of magnetic plasters on both sides of the kit, with any movement exceeding 0. 03 mm, may result in periodic white bars and bottom ash
C. Good surface coating performance, the conductivity and roughness of the surface coating of the magnetic coatings have a significant control over printing blackness and ghost shadows, the poor conductivity of the surface coatings can lead directly to the printing of ghost shadows, while low surface roughing can have a significant impact on the printing blackness by making the friction belts of carbon powder smaller. The resistance of the surface coatings has a direct impact on the print life, such as the impatience of the magnetic coatings, which can lead to the appearance of water-cording after half-cycle, with a marked reduction in the page blackness on the specific surface and a significant imbalance in the grey area。
The missing area of the magnetic surface coating and the stains lead to cyclical defects in the print page, faulty contact with the magnetic conductor's slab and the conductive steel tablet and the printer's internal contact point in the acreage drum leads to intermittent textless, imaged areas, the surface coatings are worn in such a way as to lead to light print, the round-tangular depth wear line leads to vertical white lines on the print page, and poor magnetic surface coating leads to a serious print shadow。
