Replacing the fuser and air filter kit
Your printer monitors the life of your fuser. When the fuser reaches the end of its life, the printer
displays 87 Fuser Exhausted.
It is time for you to replace the fuser kit. The fuser kit consists of a fuser and air filter. For best print
quality, make sure you replace the air filter when you replace your fuser. The air filter removes excess
dust and other contaminants from the printer.
Press
Go to clear the message. The Supplies message appears on the second line of the display to
remind you that supplies need attention.
If the top door is opened and closed, the message Did you replace Fuser? appears. If a new fuser
and air filter have not been installed, press
Stop. If a new fuser and air filter have been installed, press
Go.
If you install a new fuser and air filter before the 87 Fuser Exhausted message appeared, you must
manually reset the fuser counter. For more information, see reset the fuser counter.
To replace the fuser and air filter kit components, use the following steps or the instruction sheet
supplied with the fuser and air filter kit:
WARNING: It takes approximately 30 minutes for the oil to reach the fuser after oil bottle
installation. Make sure the oil bottle has been installed for at least 30 minutes
before printing.
