Canon PIXMA E474 - Manual (Page 180)

Maintenance tab Description
The Maintenance tab allows you to perform printer maintenance or change the settings of the printer.
Cleaning
Performs print head cleaning.
Print head cleaning removes any blockage in the print head nozzles.
Perform cleaning when printing becomes faint, or a specific color fails to print, even though all ink levels
are sufficiently high.
Deep Cleaning
Performs deep cleaning.
Perform deep cleaning when two cleaning attempts do not resolve the print head problem.
Note
• Deep Cleaning consumes a larger amount of ink than Cleaning.
Cleaning the print heads frequently will rapidly deplete your printer's ink supply. Therefore, perform
cleaning only when necessary.
Print Head Alignment
Print head alignment corrects the installation positions of the print head and improves deviated colors
and lines.
Align the print head immediately after installing the print head.
When you click Print Head Alignment, the
Start Print Head Alignment dialog box is displayed.
