There are so many laser printer parts inside your printer, the toner cartridge has two main components, one is the drum and the another is hopper. The drum begins to turn around when the printer starts to run, its surface charges with negative electricity from a charge roller. The drum has a   layer of sensitive coating on the surface, it gets hit by laser beam and as it turns. As the laser radiates the drum line by line for million times per second, it releases the electricity to create more non-electricity spaces, until they finally form an same image as the document right on the drum, just outside the hopper, there's a roller that gets covered with toner particles as the drum turns past this roller, the toner has no choice since the toner carries a negative electricity to be attracted to the non-electricity spaces on the drum, at the same time, the toner is repulsed by the negative electricity that cover the rest of the drum, so the toner only sticks to the spaces hit by the l

Fuser grease is made of silicone oil for lubrication, and it also has excellent performance at thermal conductivity to assist fuser film sleeve to conduct the fusing process. Just like other laser printer parts, we need to replace the grease with use and time, proper operation is very important to be careful when installing, otherwise your fuser film sleeve will be damaged and scrapped totally. Hope the following instruction can be of help to you. Step 1. Detach the fuser assembly and remove the used fuser film. Step 2. Use alcohol to clean the surface of heating element. Step 3. Use soft spatula to scoop up grease from the container, total applying amount is around 1 gram. Step 4. Place the spatula at an angle on the surface, and wipe evenly the grease over the surface of heating element with forward and backward movement. Step 5. Put the heating element into the fuser film sleeve, and the end of the film with ground ring should be in good contact with the surface of lo

In the past 10 years, so many printer users perform replacement of their printer parts to save money and time, so the laser printer parts manufacturers supply collections of necessary parts for users to do DIY maintenance on their printer, so this is reason why we call this set as printer maintenance kit . The parts included in the printer maintenance kit are usually fuser assembly, pickup rollers, separation pads, transfer roller and so on. -        Fuser Assembly: a component to be responsible to fuse and fix toner onto the paper. -        Separation Pad: help the pickup rollers to tug a single sheet of paper and separate it from other. -        Transfer Roller : an electrically charged roller to transfer toner from the drum to the paper. -        Pickup Roller: also named feed roller, are used to pick up the paper from the paper tray and feed it to the printing parts. Most of printers have a system that can inform you when it's time to maintain your printer, it

Upper fuser roller is made of seamless alum alloy tube, its thickness is between 1-3mm, and there is a piece of printer heating element set in such a roller to generate heat, the surface of roller is covered with the fluorine resin film, which is usually called as fuser film sleeve. When the paper pass and is jammed in the fuser assembly , just don't pull t out heavily, as such an action may damage the surface coating of the fuser roller, and the damaged parts will fail to fuse the toner particles on the paper. If the paper comes out with some spots and residual toner, it may be due to that the surface of roller is damaged or scratched. When cleaning the surface, just use some cotton with alcohol to wipe gently off the stain on it, and remember that not to use blade to scrape it.

Upper fuser roller is a component to be used with fuser film sleeve that cover over it, and there is a piece of printer heating element set in such a roller to generate heat, when the paper pass through the roller, the heat is conducted by the fuser film sleeve to melt and fix the toner particle onto the paper. When the upper fuser roller working, such an action is also assisted by the lower pressure roller that is located under it to press the melted toner particle to attach tightly onto the paper. Upper fuser roller s manufactured by Zhonghui Technology can perform excellent thermal conduction for fusing process, and it also can release heat on the paper quickly, significantly improve the print efficiency, so that’s ideal options for refurbished fuser assembly manufacturers .

You can feel hot after the paper is printed out from your laser printer, as before that, the paper pass through the fuser assembly , there is a pair of fuser rollers within the fuser assembly to apply heat and pressure to fuse the toner particles onto the paper fiber. The toner is transferred from the drum to the paper and form text and images, but that is not the last printing process, as the toner particles are still loose and easy to take off from the paper, so that need to pass through be fuser rollers to melt the powder and fix it on the paper, the upper roller sometimes we call upper fuser roller has a piece of heating element to generate heat, and there is a lower pressure roller below to press and make it more tight.
