Replace the printhead cleaning roll and aerosol filters
The printhead cleaning roll is used to clean the printheads between printing passes. It must be replaced periodically in order to maintain print quality. The frequency of replacement depends on your use of the printer: approximately monthly with average use.
An alert is displayed when 75% of the roll has been used, and again when 95% of it has been used. You can choose to replace the roll at any time.
If there is not enough of the roll to start a new job, the printer cancels the job.
Whenever you replace the printhead cleaning roll, you should also replace the aerosol filters. The roll and the aerosol filters are supplied together in the same package.
TIP: You are recommended to wear gloves during these operations.
Replace the printhead cleaning roll
1.Go to the front panel and select Replace cleaner roll from the Ink System menu 
. Any unused portion of the roll is wound on to the takeup roll at this time. You will be warned if the unused portion is more than 5% of the whole roll.
TIP: If you forget to select Replace cleaner roll at the start of this procedure, do not attempt to select it later. Instead, wait until you have replaced the aerosol filters and the cleaning roll, and then select Check cleaner roll from the Ink System menu.
