Maintaining the Printer

❏ Do not open the scanner unit or turn off 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 after repeating nozzle check and head cleaning 3 times, wait for at least 12
hours without printing, and then run the nozzle check again and repeat the head cleaning if necessary. We
recommend turning off the printer by using the
support.
❏ To prevent the print head from drying out, do not unplug the printer while the power is on.
