Important 
Cleaning consumes a small amount of ink. Deep Clean ing consumes a larger amount of ink than
Cleaning.
Cleaning the print heads frequently will rapidly de plete your printers ink supply. Consequently,
perform cleaning only when necessary. 
Note 
If there is no sign of improvement after Deep Clean ing, switch 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 r emedial action to be taken, see
