Replace the parts to be replaced periodically based on the No. of prints. If required,
replace such parts at this time.

and clean any debris with a brush or dry cloth.
If stain is serious, clean with wet cloth and then dry cloth. Be careful not to damage
the parts.
5) Cleaning of fan exhaust port
Remove the FRONT HEAD COVER and clean the FUSER FAN to remove dust deposited on it with a
brush or toner vacuum. Remove the REAR COVER and clean the dust deposit on the fan.
If the exhaust port or fan is clogged, temperature in this laser printer increases
causing trouble.
