Today it is impossible to imagine work in various industries without a computer and printer, which makes it possible to display any information used on paper. Given the increased demand for this type of technology, manufacturers have developed a huge amount of products. Despite the model diversity, the main element in all devices is the photo drum. To obtain high-quality printing text, you must closely monitor this element and timely maintain it.
What is it and for what you need?
Photo Krash – one of the main elements of any printer, which, in turn, is part of the cartridge part. It is from the drum that the clarity and quality of the received printed text depends.
The diameter of the cylindrical device is several centimeters, but its length depends on the device model. The inner part of the photobaban is absolutely hollow, there are plastic gears on the edges, it looks like a long tube. Production Material – Aluminum.
Originally, manufacturers were used as a dielectric spraying selenium, but innovative developments made it possible to apply special organic compounds and amorphous silicon.
Despite the different composition, all covers are very sensitive to ultraviolet radiation. If during transportation it was not possible to avoid contact with the solar rays, then the first time on the sheets of paper will be visible.
Device and principle of operation
Photored – the rotating shaft, which is in the sale of the cartridge, and its edges are attached to special bearings. The device coating has a selenium spraying and most often happens blue or green. Experts allocate the following working layers of the shaft:
- charge generation;
- basic coating;
- Electrically conductive base.
The principle of operation of the device is based on projection of light image on the selenium coating, In the process of which the painting element sticks to the illuminated segment of the shaft occurs. During the rotation of the device, the paint is transferred to a sheet of paper, and under the influence of high temperatures melts and sticks to it.
The refilled and serviceable cartridge is able to release more than 10,000 pages of printed text. This indicator may vary depending on the type of toner, the temperature regime in the room, humidity and quality of paper.
The following factors can reduce the work resource:
- frequent single printout;
- Use of coloring agents with large pigment particles;
- Application of rough and wet paper for printing;
- Dry temperature fluctuations indoors.
How to choose?
In order to understand how to maintain a laser printer, when purchasing it, you need to pay attention to the type of photobaban, which happens two types.
- Autonomous – The device that is located separately from the cartridge. This type of device is most often installed on professional equipment, and if there are defects and breakdowns, it requires a complete replacement to a new.
- Part of the cartridge – a universal element that is used in most types of equipment. Despite a significantly smaller resource, it can be repaired, and if necessary – cleaning. Dignity is considered low price range of component elements.
How to clean?
Despite the high resource potential of the photobraban, with a frequent operation of the printer there is a breakdown of this element, which are often associated with the incorrect use of technology. Ingestion of foreign objects and the use of poor-quality consumables can provoke the appearance of scratches, points and irregularities on the surface of the device.
The simplicity of the design of the photobraban allows not leaving the house with their own hands to carry out regular cleaning of its surface When black dots and gray shade appear on the printed sheet. To prevent these faults, experts are recommended to wipe the device immediately after it is refueling, and in no case use paint and drum of different brands.
For high-quality cleaning activities, experts are recommended to comply with a certain sequence of actions:
- disconnecting the device from the electrical network;
- Opening the front cover and cartridge extraction;
- move towards the protective curtain;
- Removing the drum;
- location of the device on a clean and smooth surface;
- removal of contamination with a special dry lint-free napkin;
- Return of the element in the device.
The main condition for high-quality work – holding shaft strictly for end areas. The slightest touch to the photosensitive element can provoke a decrease in print quality for a long time, and in some cases entail and complete the element replacement. When using wet napkins after cleaning, it is necessary to thoroughly wipe the surface with dry and clean material.
It is strictly forbidden to use sharp and rough items that can spoil the photosensitive coating, as well as solutions based on alcohol, ammonia and solvents.
Cleaning the surface with bright lighting can lead to a sensitive spraying.
Modern models of devices are equipped with an automatic cleaning system, which first functions fully, But after a certain time, wearing and fails. Specialists recommend not to miss this moment and prevent the accumulation of a large number of painting particles on the element.
Advanced printer models are often equipped with an automatic monitoring system that independently controls the status of the shaft. At the time of finding the resources of the printer on a critical mark and in a worn out state, the system displays information about the need to adopt recovery activities and writes “Replace”.
Depending on the model and type of device, the sequence of actions may be slightly adjusted, which the manufacturer will specify in detail in its instruction.
The printer is an indispensable assistant of a modern business person, the device allows you to create high-quality printed documentation. Given the high level of demand for this technique, experts recommend not to forget to carry out regular preventive inspections and cleaning the device, which will prevent the appearance of unwanted blots, dark spots and dirt on documents.
Before proceeding with the inspection of the printer, you must carefully read the manufacturer’s instruction, in which the entire sequence of actions and possible causes of malfunction is described in detail. Regular holding of a complex of simple events will avoid financial costs for the purchase of new equipment.
