Head Cleaning
This printer has an automatic nozzle check function, and automatically
performs head cleaning under normal conditions. However,
depending on the printer settings, the printout may be faint or
incorrect colors may be printed, due to a clogged print head. If this
happens, perform head cleaning by using the printer driver.
1. Turn on the printer.
2. Display the [Printing Preferences] screen of the printer driver.
3. Click [Manual Head Cleaning] on the [Maintenance And
Utilities
] tab.
The printer checks for nozzle clogs. If any found, cleaning is
performed automatically. Cleaning will be repeated 5 times at
most.
4. Perform the nozzle check to confirm the cleaning result.
