Recovering Nozzles/Purge Nozzles
Depending on the type of ink used, the ink may dry on the nozzle plate of
the cartridge if not used for some time. This is very much dependent on
ambient conditions (air temperature, air humidity). The Purging function
helps to improve such sticking characteristics after the printer has not
been used for a while. This is done by purging out a few drops of ink
before the actual printing process begins.

1 On the Home screen, navigate to Tools > Setup.
