Abstract: Provided is a technique capable of detecting the amount of a stack of discharged print media and increasing print speed. A printing apparatus includes a displacement member configured to be in contact with the discharged print media and be displaced according to the amount of the stack of the print media, and detects the stack amount based on the displacement of the displacement member. The apparatus performs a first or second detection operation based on the detected stack amount. In the first detection operation, after a specified number of print media are discharged with the displacement member positioned at the evacuation position where it does not come into contact with a print medium, the displacement member is brought into contact with the print media to detect the stack amount. In the second detection operation, the stack amount is detected with the displacement member in contact with the print media.

Abstract: Provided is a printing apparatus that prevents a print medium from buckling during discharging, a method of controlling a printing apparatus, and a storage medium. In the case where the print conveyance speed determined by the print mode is higher than or equal to the specified speed, the print medium after printing is conveyed to the discharging tray at the print conveyance speed, and in the case where the print conveyance speed determined by the print mode lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

Abstract: A movable carriage unit on which a head for discharging ink is mountable includes a fixing member movable between a fixing position for fixing the head to a mounting position and a releasing position for releasing the fixation of the head, and a moving unit including an operation portion. The moving unit is configured to move the fixing member from the fixing position to the releasing position. A guide configured to guide the head to the mounting position when the fixing member is moved to the releasing position by an operation of the operation portion is formed on the operation portion.

Abstract: An inkjet recording apparatus allows a recording head to be mounted or removed in or from a carriage at a replacement position in a region above a platen. The platen includes a short rib disposed at a position that faces an ejection port portion when the carriage moves to the replacement position and a long rib disposed at a position that faces a portion of the recording head other than the ejection port portion.
