摘要: A print apparatus is disclosed. The print apparatus comprises a print fluid application unit having a plurality of nozzles through which print fluid is to be deposited onto a printable medium during a printing operation. The print apparatus also comprises a nozzle cleaning surface to engage nozzles during a nozzle cleaning operation. The print apparatus also comprises a scanning unit and a controller. The controller is to control the print fluid application unit to deposit print fluid from nozzles of the plurality of nozzles according to an intended pattern onto the nozzle cleaning surface: control the scanning unit to scan the pattern formed on the nozzle cleaning surface: and responsive to determining. based on the scan, that print fluid from a nozzle of the plurality of nozzles has not been deposited according to the intended pattern, generate an instruction signal regarding maintenance of the print fluid application unit. A method and a machine-readable medium are also disclosed.
