Laser Components
WARNING:
This printer generates a laser beam as part of the printing
process. The laser beam in this printer is invisible. Direct eye
exposure to the laser beam may cause eye injury or blindness.
To avoid permanent eye damage, follow these directions:
Before starting any service procedure, switch off the printer power and
unplug the power cord from the AC wall outlet.
Do not disassemble the Laser Scanner Assembly.
Use caution when you are working around the Laser Scanner Assembly or
when you are performing laser related troubleshooting or repair
procedures.
Never place a mirror or a reflective tool or object in the laser beam path.
Do not disassemble the printer in such a way that the laser beam can exit
the print engine during a print cycle.
Fuser Components
WARNING:
This printer uses heat to fuse the toner image to a sheet of paper.
The Fuser Assembly is very hot. Turn Off the printer power and
wait at least 30 minutes for the Fuser to cool before you attempt
to service the Fuser Assembly or adjacent components.
Safety Components
Make sure covers and panel are in place and that all interlock switches are all
functioning correctly after you have completed a printer service call. If you
bypass, or cheat, an interlock switch during a service call, use extreme
caution when working on or around the printer.
Warning Labels
Throughout the printer, warning labels are displayed on potentially dangerous
components. When you service the printer, check to make certain that all
warning labels are in place.
Most importantly, read and obey all posted warning labels.
WARNING:
Turning the power Off using the On/Off switch does not
de-energize the printer. You must remove the power cord to
disconnect the printer from the main power source. Keep the
power cord accessible for removal in case of an emergency.
