Embodiment Construction

[0023] The present invention is described in further detail below by specific embodiments:

[0024] The reference numerals in the accompanying drawings include: lifting board 10, rotating rod 12, paper suction roller 17, lifting cam 19, crank 13, fence 15, ironing board 21, pressing block 131, elastic member 151, support plate 11.

[0025] First of all, let's explain the work of the input tray of the color laser printer: figure 1 As shown, 1) when the paper-absorbing electromagnet is excited, the driving force of the main motor is transmitted to the paper-absorbing roller 17 through the paper-absorbing gear and the rotating rod 12, thereby driving the paper-absorbing roller 17 to rotate one revolution, as figure 2 shown;

[0026] 2) At the same time, the lifting cam 19 rotates and lifts the cardboard 10, so that the first (top) paper in the input tray is loaded into the printer for printing, such as image 3 shown;

[0027] Since the above working principle already belongs...

Abstract

The invention relates to the technical field of laser printing, and in order to solve the problem of low printing efficiency in the prior art, which is caused by paper jamming in the printing processof a color laser printer due to paper damping, the invention provides a color laser printer with a function of preventing paper jamming. The color laser printer comprises a paper inlet box; the paperinlet box comprises ripping fences at two ends and a supporting plate at the bottom end; two ends of the supporting plate are connected with the ripping fences; a paper feeding structure is arranged on the ripping fences; the paper feeding structure comprises a rotating rod capable of rotating, a paper sucking roller, a lifting cam and a paper lifting plate; the paper sucking roller is mounted onthe rotating rod; the lifting cam is mounted at one end of the rotating rod; the lifting cam is connected with the paper lifting plate by a crank; the lifting cam can drive the paper lifting plate tobe lifted up; the paper lifting plate is positioned above the supporting plate, wherein chutes are formed in corresponding positions on the ripping fences, the insides of the chutes are in sliding connection with a paper ironing plate, the paper ironing plate is positioned above the paper lifting plate, and elastic parts are arranged between the paper ironing plate and the bottoms of the chutes; apressing block is arranged at one end, which is connected with the paper lifting plate, of the crank.

Description

technical field [0001] The invention relates to the technical field of laser printing, in particular to a color laser printer with the function of preventing jamming. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. According to the technology used, it can be divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers. Among them, laser printers include color laser printers. [0003] The imaging principle of color laser printers is similar to that of black and white laser printers. They all use laser scanning to form a charge latent image on the toner cartridge, then absorb the toner, and then transfer the toner to the printing paper. In daily use, paper jams are one of the most common printing failures in daily printing. After analysis, it can be known that one of the main reasons for jamming is that the...
