Fuser in this printer

Each laser printer or copier has a fuser. It is thanks to him that the paint sticks to the sheet, and an image or text appears on it. Further read in more detail about this important element. After all, without it, the coloring pigment is blurred, it is easy to stick, and the picture will be illegible and incomprehensible.

The fuser plays an important role in the printing process. It is a rubber roller with a heating mechanism inside. At the initial stage, a cartridge filled with ink disperses the ink over the paper or any surface to be printed. The ink is only on the surface and is not integrated into the texture, therefore it is not stable and the outline of the image is easily blurred. The fuser has several important functions:

  • heats the powder and helps it to fix on the paper;
  • it depends on the coordinated work of all printer nodes;
  • the speed and accuracy of the device depends on the heat and pressure created by it;
  • makes the resulting image clear and clean, without paint smudges;
  • This is a kind of final stage of processing printed documents.

IMPORTANT!The heating temperature of the fuser is 100-250 degrees, therefore when working with it it is necessary to follow safety precautions. Temperature range depending on the manufacturer may vary.

The fuser is an integral part of any laser printer, all-in-one or copier. Thanks to the development of modern technologies, it became possible to print stable images on various surfaces.

High temperature fuser and other work items cause frequent malfunctions. Overheated items can ruin the paper. Also, remove the paper should be very careful not to get burned. In the case of Teflon coating there is a risk of getting burned. Therefore, a laser device stove is not a safe element and requires some training to operate.

ATTENTION!You should know that in order to extend the service life of the device and its high-quality and stable operation, it is necessary to do timely prevention. You can do it yourself. However, this process is rather complicated, it requires professional knowledge and it is better to entrust it to service center specialists.

This element is also called the stove, thermoblock, block or fusing unit. The stove is built directly in front of the output trays. It is the last test before leaving the sheet from the printing device. In many devices, it consists of the following parts:

  • Thermofilm or top (teflon) shaft. Heated with a halogen lamp mounted inside. Provides heat to the toner and baking it on paper. This element in the stove is one of the most vulnerable and in most cases the damage is associated with it. Thermofilm is a special material that is resistant to high temperature.
  • Lower or clamping shaft. Helps the toner particles to press into the paper texture, provides a strong hold and helps the document to come out of the fastening connection. It is made of soft rubber.
  • Bushings Used for mounting Teflon shaft and tend to grind over time. Therefore, regardless of the service life and warranty over time they will have to be replaced.
  • The temperature control sensor is responsible for heating the light bulb. Thermal overload protection provides protection.
  • Cleaning felt shaft. Collects dirt and dust from each roller. It is impregnated with a special fluid that slightly lubricates Teflon.
  • Each fuser roller has extra teeth to separate the paper from them after the toner has been applied. To avoid paper jams, you should regularly clean these parts.

REFERENCE!Sometimes printers heat up for a few minutes. This may be due to the use of quartz lamps in each of the drums, which requires maximum power.

Thus, the image is created using toner and ink, and thanks to the work of the fuser is stored on a sheet of paper or other surface. The fuser is the most important part of any printer and printing device. To he served as long as possible for him requires careful and timely care.
