The suggested replacement interval for the LaserWriter Pro 810 fuser assembly is 100,000 print cycles. This compares favorably to some other Apple LaserWriter printers which have suggested fuser assembly replacement intervals of 85,000
print cycles.
The actual life expectancy of a fuser assembly can vary significantly depending on the level of preventive maintenance performed on the printer and the types of paper used in the printer.
To lengthen fuser assembly life, inspect the cleaning felt frequently. The cleaning felt cleans and lubricates the non-stick surface on the fuser roller to prevent paper, dirt, and debris from sticking to the roller and increasing wear. If the cleaning felt has a heavy coating of rust-colored or darker toner, it is a good preventive maintenance practice to replace it, even if the toner cartridge does not yet need replacing. Cleaning felts are available separately as a service part:
Cleaner, Heat roller, P/N 922-0929.
At a minimum, replace the cleaning felt with each toner cartridge. A new cleaning felt is provided with each toner cartridge.
