The fuser in the printer is

Every laser printer or copier has a fuser. It is thanks to it that the paint sticks to the sheet, and an image or text appears on it. Read on to learn more about this important element. After all, without it, the coloring pigment is washed out, it is easy to blow away, and the picture will be illegible and incomprehensible.

What is a fuser in a printer?

The fuser plays an important role in the printing process. It is a rubber roller with a heating mechanism inside. In the initial stage, a cartridge filled with ink disperses ink onto the paper or any surface intended for printing. The ink is only on the surface and is not integrated into the texture, therefore it is not stable and the outline of the picture is easily blurred. The fuser performs a number of important functions:

• heats the powder and helps it stick to the paper;
• the coordinated operation of all printer components depends on it;
• the speed and precision of the device depends on the heat and pressure it creates;
• 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, so when working with it you must follow safety precautions. Temperature conditions may vary depending on the manufacturer.

In which printers does it occur?

The fuser is an integral part of any laser printer, multifunction device or copy machine. Thanks to the development of modern technologies, it has become possible to print durable images on various surfaces.

High temperatures of the fuser and other operating parts cause frequent failures. Overheated elements can damage paper. You should also remove the paper very carefully so as not to get burned. In the case of Teflon coating, there is a risk of getting burned. Therefore, the 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 quite complex, requires professional knowledge and is best left to specialists from service centers.

What does it look like, what is it called differently

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

• Thermal film or upper (Teflon) shaft. Heated by a halogen lamp installed inside. Provides heating of the toner and baking it onto the paper. This element in the stove is one of the most vulnerable and in most cases, breakdowns are associated with it. Thermal film is a special material that is resistant to high temperatures.
• Bottom or pressure shaft.Helps the toner particles to be pressed into the paper texture, provides reliable clamping and helps the document come out of the fastening joint. Made from soft rubber.
• Bushings. They are used to fasten a Teflon shaft and tend to wear off over time. Therefore, regardless of service life and warranty, they will have to be replaced over time.
• The temperature control sensor is responsible for heating the light bulb. Overheating protection is provided by a thermal relay.
• Cleaning felt roller. Collects dirt and dust from each roller. It is impregnated with a special liquid that slightly lubricates the Teflon.
• Each fuser roller has additional teeth to separate paper from them after toner has been applied. To avoid paper jams, you should clean these parts regularly.

REFERENCE! Sometimes printers take several minutes to warm up. This may be due to the use of quartz lamps in each of the drums, which requires reaching maximum power.

Thus, an image is created using toner and ink, and thanks to the operation of the fuser, it is saved on a sheet of paper or other surface. The fuser is the most important part of any printer and printing device. In order for it to last as long as possible, it requires careful and timely care.
