Parts Laser Printer
Laser Printer is one of the most important printers in the world to feature a high-specification, which is a very important device in our process because of their saving time and effort they are printing, scanning, imaging and work as a fax
Where work is like photocopier
Facilitated this printer human acts, as they intervene in every Majallat (home - work-office-institutions-ministries-association)
The manufacturers of laser printer add several extensions have
The surveyor light to copy paper to computer
And photocopying were added feeder automatic paper to facilitate the imaging process
It has also been added unit of fax and telephone to send and receive securities through Amad
It was add a network to be able Aktar from a user to print an example of setting a printer in the work of the office has a more than one employee
Enable all employees of the printing at the same time and thus be provided to the enterprise number of printers
A group key parts, and there is a secondary group. You will learn now, the main parts, for easy after the piece to determine any malfunction
Main parts:
1. sheet feeder:
From parts of the job to the printer is the paper feeding center, where it's part responsible for pulling the paper from the outside to the inside, commensurate with the printer movement in terms of time and the way the clouds as it works to prevent the withdrawal of most of the paper in the printer in order to stop the paper does not happen, where there is down lashes clouds lashes Other works on the organization of the paper entry
They vary in shape and sometimes in the way the work of another printer, they contain several parts:
* Lashes paper pull.
* Lashes paper organization.
* Paper sensor.
When you start a currency printing senses the sensor existence of paper whereupon lashes nutrition to withdraw the paper for the inside, down the paper and there is the so-called whipped paper organization, as it works to prevent the entry of more than one sheet of paper.
2. Unit Paper Transfer:
Is a several parts scattered in the printer, where it is working on the transfer of paper from one unit to the sheet feeder to the printer, whereupon coordination with all parts of the printer so that they convey the paper from another part by the mechanism of the printer, Vtmr paper from start to finish by the transport unit
. They contain:
* Lashes clouds.
* Roll a metal or plastic to carry lashes clouds.
3. Unit laser radiation
The unit is very accurate in the work and do not tolerate any dust or touch, is a unit working on drawing the image to be photographed or printed on the form of a picture of Sirh light on the unit AOPC,
They are used beam laser is invisible spreads OPC to form a mirror image of the original image, and any obstacle in the path of the beam causes a defect in the image to be printed
Their parts
* Laser source
* Lenses are concave to determine the laser and organization size.
* Mirrors to reflect and guide the laser.
4. Unit endorsement (inker)
It is a major and very important unit, where it is working on a fee matching the image of the image to be printed in the form of granules of carbon powder (ink) on paper.
Where it's the laser beam receives the OPC charged positively charged who shall beam unloading cargo and painted beam is identical to the original image, then the positive charges on the OPC attracting ink granules negative on OPC Vickl image of ink on OPC are inverted, and then comes the paper down OPC are paper Shipping negatively charged stronger than charging OPC attracts the ink on the paper to OPC properly (non-inverted), after which the paper will take you through the transport unit to unit installation
Their parts:
* (OPC).
* Shipping column OPC
* Ink transfer column.
* Ruler cleaning ink
* Ink container.
5. Charging Unit (static electricity high voltages)
Charging Unit with most of the work, they are responsible for the transfer of ink from OPC to the paper through the ink charging signal minus shipping paper positively charged higher shipment ink, attracted ink from OPC to the paper, and there is other work, a clean OPC of excess cargo after completion of the printing
They use high static shipments of up to 7,000 volts so you can work
The transfer of a relatively heavy ink from the ink column to OPC and then to the paper needs a high-voltage
6. The unit installation
Alsaolh is the unit for installing the ink particles on the paper, through pressure and heat, enters the paper inside the unit installation, specifically between the two wheels on each Amadgoutin high Hrarathma up to 300C Vtaml heat and pressure to install the ink on the paper.
After the arrival of the paper through the transport unit, the paper between two compressed interference on each other
The upper column contains the heating bulb and thus the temperature is high, Vtaml this Thermal to melt the ink on the paper by pressing and heat, to get beyond the static image
Their parts
* Roll cutaneous pressure
* Roll a metal or plastic heat-resistant
* Bulb heating
7. Unit sensors:
Is a unit deployed in all the places the conduct of the paper, which organized the printing process through the sensor location and arrival of the paper to give a signal to the part of the work, too, which provide a signal when the faltering paper inside the printer and determining the position of tripping
This sensor is a diode Luminous versus a tranny to receive the light emitting diode
There between the diode and the transistor boycotted the plastic when it hits the paper it rises from within the sensor, the printer senses the whereabouts of the paper
8. Unit and energy control
It is in charge of the unit for the operation of both a printer and supply the appropriate power of each part, and the printer's control signals.
They are containing the control panel and the entrance to the USB in addition to high-energy unit used in the ink charging process
And also it contains paintings additions of fax and Escanr Network
