Printing and Paper Handling - Fuser Roller Cleaning Components

Fuser Roll Cleaning Components

Components that oil as well as clean           
Most toner-based printer engines use hot rollers to fuse the latent toner image onto the paper. Schlegel offers a variety of high-performance cleaning components, which remove the toner residues that accumulate on these fuser rollers. Although some components solely have a mechanical cleaning function, most of them also dispense silicone oil.

Oil rollers
Schlegel has developed a range of different systems for applying silicone oil on fuser rollers to clean them. As the fuser area operates at temperature of 200°C or above, all the materials used have to be designed to withstand these extreme temperatures. Aramid yarn resists high temperatures. It is used to produce a brush fabric that is wrapped around a core containing high-viscosity silicone oils. A number of different oil storage media can be used, including felt, foam, paper, ceramic foams and hollow shafts. Constant and uniform dispensing of the oil together with a continuous cleaning action is essential to ensure these components enjoy a long service life.

Oil cleaning webs
Your guarantee of constant cleaning and oiling. The type of non-woven material to choose depends on the type of cleaning desired, as well as the temperature range and oil dispensing required. Possible materials include nylon, polyester, aramid, Teflon and blends. Oil webs require a more expensive machine that includes a drive mechanism. But the superb cleaning and oiling they provide is more than justified in high-volume and colour printers.

Oil pads
Stationary high-temperature brushes or velvet strips impregnated with silicone oil are used as a cost-effective, low-performance alternative.
