Cleaning the Printhead from the Printer
1
Ensure that the printer is on.
2
Hold down the RESUME/CANCEL button until the POWER lamp flashes once.
Now the POWER lamp starts flashing and print head cleaning begins. Do not perform any
other operations until the head cleaning finishes.
After printhead cleaning finishes, print the nozzle check pattern to verify that the printhead
is clean. If not, repeat printhead cleaning. If the printhead is still not clean after the third
cleaning, perform printhead deep cleaning.
