Red printing is the same with the programmed control process of black print.
Red-black double-colored printing (in this example, black toner cartridge (the first toner cartridge) is front, and red toner cartridge (the second toner cartridge) is rear):
Before print paper motion arrives black print sensor, main control chip repeatedly reads the feedback voltage being respectively used to black and the red transfer roll printed, for determining the environment residing for current printing, after print paper arrives black print sensor, come on the transfer roll of black print, main control chip reads the feedback voltage of the transfer roll of black print, decide the transfer printing high pressure that in print procedure, black print uses, main control chip controls black print laser scanner output black print data, photosensitive drums black print data being passed to black toner cartridge (the first toner cartridge) forms sub-image, through development and transfer process, black print data are imprinted on paper with the form of powdered black ink again, along with the motion of print paper, after print paper arrives red print sensor, come on the red transfer roll printed, main control chip reads the feedback voltage of the red transfer roll printed, decide the red transfer printing high pressure printing use in print procedure, main control chip controls red printing laser scanner output red print data, the photosensitive drums red print data being passed to red toner cartridge (the second toner cartridge) forms sub-image, then through development and transfer process, red print data is imprinted on paper with the form of red ink powder, when print paper leaves the transfer roll of black print, adjustment black transfer voltage, when leaving the red transfer roll printed, red transfer voltage, when print paper spues, print procedure terminates, closeall charging voltage, developing voltage and transfer voltage, stops the running of all laser scanners, stops the running printing motor and printing mechanism.
Control circui is as follows:
1, in high-tension circuit, except the devices such as the resistance of necessity, electric capacity and inductance, high voltage package is also had.Two groups of high-tension circuits are independent, and wherein two transfer printing circuit feed back transfer voltage signal respectively, and feedback signal is used for controlling in real time transfer voltage value.
2, Halogen lamp LED switch is controlled by comparer, the too high automatic closedown of temperature, controls front end and has protection circuit (having thermostat in circuit), during to prevent from crashing suddenly, and Halogen lamp LED continuous heating and breaking out of fire.
3, fan control is according to the feedback of real time temperature, can carry 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, laser scanner control circuit adopts general logical device (mainly Sheffer stroke gate logical device) to carry out logic control.
6, the charging voltage in high voltage control, developing voltage are switch control rule, and transfer voltage is width modulation (PWM) Duty ratio control, carries out duty cycle adjustment by transfer voltage value of feedback.
7, sensor is realized by optocoupler and microswitch.
Principle of work of the present invention:
Printing principle is, print command becomes laser beam by procedure turns, laser beam is mapped in photosensitive drums from the first toner cartridge 7 and the second toner cartridge 8 out entering into correspondence laser scanner 14 after level crossing 15 reflects again, first toner cartridge 7 and the second toner cartridge 8 are attached to ink powder on paper again according to print command respectively under the cooperation of two transfer means assemblies 9, form printed drawings picture.
Under normal working environment, after user have input print command, paper from paper storehouse out after will print the first color through the first toner cartridge 7 and first transfer means assembly 9, and then print the second color through the second toner cartridge 8 and second transfer means assembly 9, eventually pass and fixingly complete printing.
When user needs 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 outwards can 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 use the red-black pattern printed, and only need the ink powder red part in toner cartridge being changed into the color of needs.If need the printing expanding to more colors, just need to increase laser scanner, transfer means assembly and toner cartridge, high-tension circuit and optocoupler sensor will be increased in corresponding circuit, will increase in corresponding programmed control and the judgement of other color print is printed with the intersection realized between different colours.
According to the above description, the solution of the present invention can be realized in conjunction with art technology.
