Maintenance tab Description
The Maintenance tab allows you to perform machine maintenance or change the settings
of the machine.
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.
Ink Group
When you click Cleaning or Deep Cleaning , the Ink Group window is displayed.
