Every toner based printer or copier has a fuser if your printer takes a toner cartridge
then guess what you have a fuser.
Fusers perform one function that is to melt the toner in to the fiber of the paper
fusing assemblies do this by high heat and by pressure between the rollers located inside the fuser.
Old Fuser Technology
Earlier fuser technology required the use of a tungsten filament sealed lamp filled with an inert gas that heated up extremely hot inside an aluminum cylinder this was regulated by a thermostate to make sure it didnt get to hot or have a melt down " fuser meltdown" is what we use to call it the heat generates basically the same as a floor or space heater that you can purchase at your local store.
New Fuser Technolgy
The newer technolgy used by the printer manaufacturers is called a heating element and sleeve
these fusers no longer need heat lamps and they warm up to temp within seconds using a ceramic glass element , the problem however is they now use a sleeve that resembles camera film and the sleeve has teflon coatings on it which causes the toner not to stick, Similar as your pans at home and after long periods of time this teflon coating wears off and then the toner is not being fused correctly to the paper print quality goes down hill and in most cases the sleeve fails as shown in the pictures below.
The Photo below is a good picture of the newer heating element technology on top
the lower picture is the tungsten lamp older fuser technology
Fusers dont last long typically 100,000 to 200,000 pages is all there good for most printer
manufacturers will say they last longer and all printers are rated differently concerning fuser life expectancy
but by running envelopes and heavy paper stock through the printer you will cause your printers
fuser to shorten its life span if you want to prolong the life of your printer's fuser then be careful of what you run through it.
