Important:
❏ Do not open the Ink supply unit cover or turn o the printer during head cleaning. If the head cleaning is
incomplete, you may not be able to print.
❏ Head cleaning consumes ink and should not be performed more than necessary.
❏ When ink is low, you may not be able to clean the print head.
❏ If print quality has not improved aer repeating nozzle check and head cleaning 4 times, wait for at least 6 hours
without printing, and then run the nozzle check again and repeat the head cleaning if necessary. We recommend
turning o the printer by using the
P button. If print quality has still not improved, run Power Cleaning.
