The discounting of the Bondi Blue ones and the introduction of the colored models are the reasons. I had the opportunity to work on an Apple LaserWriter LS this last month. Contact an authorized service provider. The fuser in a laserjet printer permanently fixes the toner to the paper. The fusing is accomplished with heat and pressure.
Pressure is applied with a pliable rubber roller.
When a developed page is passed between these two rollers, heat from the one roller melts the toner and pressure from the other roller squeezes molten toner into the paper fibers where it cools and adheres permanently. My first impression was to just replace the fuser assembly. And getting the fuser out of the printer just involves removing 5 screws. The lamp is about a quarter inch in diameter and twelve inches long. It sets in the middle of the hollow fusing roller.
