If the nozzles are clogged, the printouts become faint, there is visible banding, or unexpected colors appear. Selecting Adaptive Head Cleaning repeats a nozzle check and cleaning cycle to clean the print head.
When there is a problem in printing quality or when printing large quantities, we recommend using the Adaptive Head Cleaning feature. Select the menus on the printer's control panel as described below.
Do not open the front cover or turn off the printer during Adaptive Head Cleaning. If the print head cleaning is incomplete, you may not be able to print.
Because Adaptive Head Cleaning may repeat print head cleaning several times, it may take a long time and consume a large amount of ink.
Because print head cleaning uses some ink, it may not be performed when ink is low.
Drying causes clogging. To prevent the print head from drying out, always turn the printer off by pressing the 
button. Do not unplug the printer while the power is on.
