Publication number: 20190358959Abstract: Fluid supply apparatus 104 is disclosed. The fluid supply apparatus 104 comprises a first conduit 106 lo supply fluid to a fluid dispense head and a second conduit 108 to receive fluid from the fluid dispense head. The first conduit 106 and second conduit 108 may both supply print fluid to a print head in a printing or servicing configuration. The first conduit 106 and the second conduit 108 are coupled together via a closable third conduit 116. The closable third conduit 116 permits fluid flow between the first conduit 106 and the second conduit 108. The third conduit 116 comprises deformable walls movable towards each other to close the third conduit 116 to the passage of fluid between the first 106 and second conduit 108.Type: ApplicationFiled: April 24, 2017Publication date: November 28, 2019Inventors: David Butinya, Pol Vinardell, Marta Coma Vives

Publication number: 20190358961Abstract: 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.Type: ApplicationFiled: August 9, 2019Publication date: November 28, 2019Inventors: Katsunori NISHIDA, Yoshinori KATO
