How do I replace the fuser unit?
Follow the steps below:
Please wait for 30 minutes after installing a new Fusing Unit the oil circulates completely through to the Heat Roller. If you begin using a new Fusing Unit immediately, poor print quality may result.
When removing the Fusing Unit from the printer, be sure to keep the Fusing Unit flat so that oil will not spill. Damage can occur if oil is spilled inside the printer.
If the condition of the Fuser Cleaner is poor, we recommend that you replace the Fuser Cleaner at the same time as the Fusing Unit. The life counter for the Fuser Cleaner will need to be reset. Click here to see how to replace the Fuser Cleaner.
