Cleaning the Print Head from the Printer
This operation cleans all nozzles, both black and color. Because this method also resets the
printer, any print data stored in the printer is lost.
1
Ensure the printer is on.

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. This takes about 40 seconds.
After print head cleaning finishes, print the nozzle check pattern to verify that the print head
is clean. If not, repeat print head cleaning. If the head is still not clean after the third
cleaning, perform print head deep cleaning.
