Make sure that the protrusion on the cap touches the side of the print heads when pressing the carriage in the maintenance
direction. Non-ejection may occur if the carriage comes in contact with the nozzle surface of a print head.
(7) Pull out the pin inserted in A and turn the lever clockwise until the lever comes in contact with the pin inserted in B.
