The programmed control process that red printing is printed with black is the same.
Red-black double-colored printing (black toner cartridge in this example (the first toner cartridge) is front, and red toner cartridge (the second toner cartridge) is rear):
Before the print paper motion arrives the black print sensor, main control chip repeatedly reads the feedback voltage that is respectively used to black and the red transfer roll of printing, for determining the residing environment of current printing, after print paper arrives the black print sensor, come on the transfer roll of black printing, main control chip reads the feedback voltage of the transfer roll of black printing, decide black in print procedure to print the transfer printing high pressure used, main control chip is controlled black and is printed laser scanner output black print data, the black print data is passed on the photosensitive drums of black toner cartridge (the first toner cartridge) and formed sub-image, the form with powdered black ink is imprinted on paper by the black print data for process development and transfer process again, motion along with print paper, after print paper arrives red print sensor, come on the red transfer roll of printing, main control chip reads the feedback voltage of the red transfer roll of printing, decide the red transfer printing high pressure used of printing in print procedure, main control chip is controlled the red laser scanner output red print data of printing, red print data is passed on the photosensitive drums of red toner cartridge (the second toner cartridge) and is formed sub-image, then through development and transfer process by red print data, the form with red ink powder is imprinted on paper, when print paper leaves the transfer roll of black printing, adjust the black transfer voltage, while leaving the red transfer roll of printing, red transfer voltage, when print paper spues, print procedure finishes, and closeall charging voltage, developing voltage and transfer voltage, stop the running of all laser scanners, stops printing the running of motor and printing mechanism.
Circuit is controlled as follows:
1,, in high-tension circuit, except the devices such as necessary resistance, electric capacity and inductance, also has high voltage package.Two groups of high-tension circuits are independent, and wherein two transfer printing circuit feed back respectively the transfer voltage signal, and feedback signal is for controlling in real time the transfer voltage value.
2, the Halogen lamp LED switch is controlled by comparer, and excess Temperature is closed automatically, and control front end and there is holding circuit (thermostat is arranged in circuit), when preventing from crashing suddenly, Halogen lamp LED continuous heating and breaking out of fire.
3, fan control, according to the feedback of real time temperature, can be carried out half-power and capacity operation.
4, the control circuit of the integrated 6 line stepper motors of motor driver, easy and simple to handle.
5, the laser scanner control circuit adopts general logical device (main right and wrong gate logic device) to carry out logic control.
6, the charging voltage in high voltage control, developing voltage are that switch is controlled, and transfer voltage is width modulation (PWM) Duty ratio control, by the transfer voltage value of feedback, carries out duty cycle adjustment.
7, sensor is realized by optocoupler and microswitch.
Principle of work of the present invention:
The printing principle is, print command is transformed into laser beam by program, laser beam is mapped on photosensitive drums from laser scanner 14, out after level crossing 15 refractions, entering into corresponding the first toner cartridge 7 and the second toner cartridge 8 again, the first toner cartridge 7 and the second toner cartridge 8 are attached to ink powder on paper according to print command respectively under the cooperation of two transfer means assemblies 9 again, form print image.
Under normal working environment, after the user has inputted print command, paper will be printed the first colors through the first toner cartridge 7 and first transfer means assembly 9 after out from the paper storehouse, and then print the second color through the second toner cartridge 8 and second transfer means assembly 9, complete printing finally by crossing photographic fixing.
When the user need to change toner cartridge, first the door of front panel is opened, extract toner cartridge pull support 1 out, now toner cartridge pull support 1 can outwards slide along left toner cartridge pull bracket side slideway 2 and right toner cartridge pull bracket side slideway 3, then change the first toner cartridge 7 and the second toner cartridge 8, then, then push back toner cartridge pull support 1, finally shut the door of front panel, complete the replacing of toner cartridge.
All double-colored printings can be used the red-black pattern of printing, and the ink powder that only need to change the red part in toner cartridge into need color gets final product.If need to expand to the printing of more colors, just need to increase laser scanner, transfer means assembly and toner cartridge, will increase high-tension circuit and optocoupler sensor in corresponding circuit, will increase the judgement that other color is printed in corresponding programmed control and print to realize the intersection between different colours.
According to the above description, can realize the solution of the present invention in conjunction with art technology.
