Deep Cleaning (Head Refreshing)
Use if you have tried the Cleaning option several times and there has
been no improvement in printing results. Deep Cleaning will give the
printhead an even deeper clean than Cleaning (Head Cleaning).
Click Deep Cleaning (Head Refreshing) and when the following
dialog box appears, click OK. In Windows 2000/XP, a confirmation
message does not appear. Cleaning begins immediately when you
click Deep Cleaning. Do not perform another operation while the
printhead is being cleaned.
Please note that Deep Cleaning will use even more ink than Cleaning.
