The structure of the commonly used heating roller section is simply explained:

There are both spiral and reciprocating types, but nowadays many spiral types are used, and the reciprocating types have gradually been screened.

The advantage of the spiral type is that the generated thrust is large. Because it rotates during the pushing process, frictional heat can occur, so it can be used with less energy.

The first type of screw is enough to be a screw, and the first structure of a plunger is a plunger.

Protection of heating rollers

After a long period of use, the fuser heating roller is coated with a layer of toner, which causes black marks on the print. Wipe clean with absorbent cotton dipped in water. Do not scrape with a blade to prevent damage to the fuser heating roller.

Photoelectric sensor protection

Contaminated photoelectric sensors can cause the printer to fail to detect. If the manual paper feed sensor is contaminated, the printer control system cannot detect the paper signal, and the manual paper feed function is disabled. Therefore, you should use absorbent cotton to scrub and clean the relevant sensors to keep them clean and always have sensory sensitivity.

There are two commonly used methods for the correction of heating rollers: in-situ cutting (grinding) processing correction method and in-situ overlay welding correction method.

(1) In-situ cutting (grinding) machining method

The operation method of the in-situ cutting (grinding) processing method is: Install a dedicated knife holder on the frame of the crusher, and the moving track should be parallel to the axis of the heating roller. When the correction is started, the crusher is started, and the manual feed structure (or the automatic feed structure may be selected if necessary) is used to cut the roller. Pay attention to the following points when using this method:

① The running track of the tool holder is parallel to the axis of the heating roller, so as to avoid taper after cutting and affect the crushing effect.

② Control the speed of the heating roller. The linear speed of the surface of the heating roller roll should not exceed the allowable cutting speed of the cutting tool, otherwise a speed reduction method should be adopted to avoid damaging the tool.
