To clear this error, select Clear Warning from the control panel’s
Reset Menu. For instruction about accessing the control panel
menus, see “How to access the control panel menus” on page 171.
Turn the Image Optimum setting off on the control panel’s Printing
Menu if you do not want the printer to automatically lower the
print quality to continue printing.
You may need to increase the amount of printer memory to be
able to print at the desired print quality for your document. For
more information on adding memory, see “Memory Modules” on
page 232.
Install Fuser
There is no fuser unit installed or the fuser unit is not installed
properly. Turn off the printer and install the fuser unit if it is not
installed.
If a fuser unit is already installed, turn off the printer, open cover
A, then open cover D. Then close cover A and open cover B.
Remove the fuser unit, then reinstall it properly. Close covers D
and B. The error clears automatically if the fuser unit is properly
installed.
If the error is not cleared, the fuser unit is out of order. Replace it
with a new fuser unit.
