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.
Printer fuser assembly, as known as fuser kit or fuser unit, it's the component that works with heat and pressure to melt and fix the toner particle onto the paper, such type of part need to repair or replace when your printer has printed out certain amount of pages. In addition to the fuser unit , there are other interchangeable parts that need to replace and are available on the market, such as pickup roller, separation roller, separation pad and transfer roller. Many manufacturers pack a whole set of these parts and sell them together, we usually call them as maintenance kit. Nowadays, maintenance kit is very popular solution for the printer users to maintain their printers, but there are many products by different producers on the market, so sometimes we need to pay particular attention to the quality you get from them, though good quality kit is a little more expensive, but durable and long run can low down your page cost.
