摘要： A discharge portion includes a discharge face on a first direction side. A support portion supports the discharge portion on a second direction side. A wiper can move from a third direction side to a fourth direction side of the discharge face. The third direction and the fourth direction orthogonally intersect the first direction and the second direction. A first cover portion covers an edge on the third direction side of the support portion and includes a first flat face part which is provided parallel to the discharge face and located to the first direction side of the discharge face. A second cover portion covers an edge on the fourth direction side of the support portion. The second cover portion includes a second flat face part. The second flat face part is provided parallel to the discharge face and to the second direction side of the discharge face.

摘要： A processor of a print device performs empty processing in a case where it has determined that it has received, from a remaining ink amount detector, a first signal that indicates that a remaining amount of an ink is not greater than a first prescribed amount. The processor also performs the empty processing in a case where it has not determined that it has received the first signal, but has determined that it has received a second signal. In the empty processing, the processor performs soak cleaning of a nozzle face and stores an empty soak standby flag in an EEPROM. The empty soak standby flag is a flag that prohibits the performing of a printing operation. Therefore, the print device is able to reduce the possibility that a decline in print quality will occur.

摘要： A print device includes a processor and a memory. The memory storing computer-readable instructions which, when executed by the processor, perform processes. The processes include covering processing controlling a cap into a covering state in which the cap covers a nozzle. The processes include first purge processing purging, in a state in which the cap is in the covering state and a supply valve is closed, an ink from the nozzle by operating a pump at a first rotation speed. The processes include injection processing injecting, after the first purge processing and in a state in which the cap is in the covering state and the supply valve is open, the cleaning liquid into the interior of the cap by operating the pump at a second rotation speed to cause the cleaning liquid to soak a nozzle face.

摘要： The inkjet printer includes a head, a circulation flow path, a cap, a first pump, and a control unit. The head has a nozzle surface having nozzles to eject ink. The circulation flow path circulates ink. The cap can contact the nozzle surface. The first pump is connected to an exhaust hole formed in the cap. In a soaking processing, the processor drives the first pump and causes the nozzle surface to be soaked in liquid, in a capping state in which the cap is in contact with the nozzle surface. In a circulation processing, the processor causes the ink to circulate in the circulation flow path in a state in which the nozzle surface is soaked in the liquid, after the soaking processing.

摘要： A print device includes a processor, and a memory. The processor performs processes. The processes include a covering control processing controlling the cap into a covering state in which the cap covers the nozzle. The processes include supply processing supplying, after the covering control processing, the cleaning liquid to the cap from the supply flow path. The processes include hold processing holding, after the supply processing and in a state in which the cleaning liquid has soaked the nozzle face, the cleaning liquid in the cap. The processes include first determination processing determining, after the hold processing, whether a print request has been received. The processes include discharge processing discharging, in a case where a power on signal has been detected or in a case where the first determination processing has determined that the print request has been received, the cleaning liquid that has been held in the cap.
