Cleaning the Print Head from the Printer
1
Ensure 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 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.
