[0037]

[0038] As the liquid discharge apparatus 10 according to the first embodiment (see figure 1 and figure 2 ), an inkjet printer that performs printing on a recording medium M by discharging ink is explained below. The liquid discharge device 10 is not limited to an inkjet printer that discharges ink as liquid. The liquid discharge device 10 may be a liquid discharge device that discharges any liquid other than ink.

[0039] The liquid discharge apparatus 10 of the line head system is employed in the first embodiment. The liquid discharge apparatus 10 includes a head unit 11 , a platen 12 , a tray 13 , a conveyor 14 , a storage tank 15 and a controller 60 . The head unit 11 includes one or more (for example, four) discharge heads 11a. The discharge head 11a is longer than the recording medium M in the width direction.

[0040] Each discharge head 11a includes a passage forming body and a volume changing portion. The inside of the channel-forming body is provided...

[0141] Such as Figure 12 As depicted in , the liquid discharge device 10 according to the second embodiment includes a temperature sensor 70 that detects the temperature in the liquid discharge device 10 . Any other configuration than the temperature sensor 70 is similar to that in the first embodiment, and thus an explanation thereof is omitted.

[0142] The temperature sensor 70 is a sensor that detects the temperature of air in contact with the meniscus of ink formed in the nozzle hole 21 a of the head chip 20 . For example, the temperature sensor 70 is provided in the discharge head 11 a in the liquid discharge apparatus 10 . The temperature sensor 70 detects the temperature around the discharge head 11 a , which is the temperature in the liquid discharge apparatus 10 . The detected temperature may be corrected based on a predetermined correspondence between the detected temperature and the temperature in the vicinity of the nozzle hole 21a.

[0151] Such as Figure 12 As depicted in , the liquid discharge device 10 according to the third embodiment includes a humidity sensor 80 that detects humidity in the liquid discharge device 10 . Any other configuration than the humidity sensor 80 is similar to that in the first embodiment, and thus an explanation thereof is omitted.

[0152] The humidity sensor 80 is a sensor that detects the humidity of air in contact with the meniscus of ink formed in the nozzle hole 21 a of the head chip 20 . For example, the humidity sensor 80 is provided in the discharge head 11 a in the liquid discharge apparatus 10 . The humidity sensor 80 detects the humidity around the discharge head 11 a , which is the humidity in the liquid discharge apparatus 10 . The detected humidity may be corrected based on a predetermined correspondence between the detected humidity and the humidity in the vicinity of the nozzle hole 21a.

Abstract

The invention provides a liquid discharge apparatus, a liquid discharge method and a non transitory computer-readable medium. There liquid discharge apparatus includes: a conveyer; head chips; a circulation channel; and a controller. Each head chip includes a manifold; a nozzle group, and actuators. Each head chip is configured to execute discharge drive and non-discharge vibration drive. The headchips include: an end head chip; a facing head chip facing the recording medium; and a non-facing head chip not facing the recording medium. The controller is configured to make at least one of a circulation flowing amount of a liquid in the circulation channel in the facing head chip and a frequency of the non-discharge vibration drive by an actuator included in the actuators in the facing headchip larger than those of the non-facing head chip. The medium stores a control program corresponding to the method.

Description

technical field [0001] The present disclosure relates to a liquid discharge device, a liquid discharge method, and a non-transitory computer-readable medium storing a control program for the liquid discharge device. Background technique [0002] There is conventionally known an inkjet printer including: an inkjet head including nozzles; a circulation channel through which ink circulates between the inkjet head and a tank; and a battery storing electric power for maintenance. When power is supplied to the inkjet printer from an external power source, the inkjet printer performs a precursor for applying vibration to ink without discharging ink from nozzles, and circulates ink through a circulation channel. When power is not supplied from an external power source, the inkjet printer performs a precursor using power from a battery, but there is no ink circulation. Contents of the invention [0003] In the inkjet printer described above, maintenance methods for dealing with im...
