Parts are controlled as spare parts. When servicing parts that have no procedures, care-
fully observe their assembly detail before starting the service.
Refer to the manual for optional parts.
Unless necessary, optional parts should not be removed when performing a service oper-
ation.

1.1 Before starting service work

Turn the printer power OFF and remove the power cord from the outlet before beginning a proce-
dure.
When working on, or around the FUSER ASSEMBLY, ensure the temperature has cooled suffi-
ciently.
Applying unreasonable force to the parts or hardware while servicing the printer may cause them
to break or compromise their performance.
Be sure to use the correct screw for the application. Different screws are used for plastic and sheet
metal. Incorrect use of the screw type may result in damage to the screw threads or other hard-
ware.
Locations on the frame where the character "TAP" is stamped, should use the screws
designated for plastic.
Remove the 150 Sheet Paper Cassette, 550 Sheet Paper Cassette and the EP Cartridge. Place
the components in a safe place during servicing.
Damage to sensitive electronic components should be avoided by grounding the body using a wrist
band or other suitable Electrostatic Discharge (ESD) tools.
