Deep Cleaning  consumes a larger amount of ink than  Cleaning.
Cleaning the print head frequently will rapidly deplete your printer's ink supply. Consequently, perform
cleaning only when necessary.
Note
•
If there is no sign of improvement after  Deep Cleaning, turn off the printer, wait 24 hours, and then
perform  Deep Cleaning  again. If there is still no sign of improvement, the ink may have run out or the
print head may be worn. For details on the remedial action to be taken, see "
Ink Is Not Ejected ."
