Purge Test

Perform this test with a black print cartridge installed.

This test prints out a nozzle test pattern followed by several grey lines and another nozzle test pattern. Use this test to check the func- tion of all the nozzles in the print cartridge. This test also checks the electronic connection to the print cartridge. During the test, the print cartridge head goes through a maintenance cleaning at the mainte- nance station.

Running this test with a color print cartridge installed will clear the nozzles in the cartridge.
