Liquid processing device, control device, and method
According to one embodiment, a liquid processing device includes a liquid flow path connected to a liquid ejecting head. A control unit is also provided. The control unit is configured to begin an operation to cause liquid to flow in the liquid flow path to the liquid ejecting head, receive a pressure value for liquid in the liquid flow path, and stop the operation when the pressure value is outside a normal range. Such a device can avoid damage resulting from malfunctions and the like.
1 . A liquid processing device, comprising:
a liquid flow path connected to a liquid ejecting head; and
a control unit configured to:
begin an operation to cause liquid to flow in the liquid flow path to the liquid ejecting head,
receive a pressure value for liquid in the liquid flow path, and
stop the operation when the pressure value is outside a normal range, wherein
the stopping of the operation when the pressure value is outside the normal range occurs after a predetermined period of time elapses after the receiving of the pressure value that is outside the normal range.
2 . The liquid processing device according to claim 1 , wherein the normal range depends on a target pressure value for liquid in the liquid flow path.
3 . The liquid processing device according to claim 1 , wherein the control unit is further configured to:
cause a notification to be output when the pressure value is outside the normal range.
4 . The liquid processing device according to claim 3 , wherein the notification is an audible sound.
5 . The liquid processing device according to claim 3 , wherein the notification is a visual display on a display screen.
6 . The liquid processing device according to claim 3 , wherein the notification includes a visual display on a display screen and an audible sound.
7 . A control device for a liquid processing device, the control device comprising:
a processor configured to:
begin an operation to cause liquid to flow in a liquid flow path to a liquid ejecting head,
receive a pressure value for liquid in the liquid flow path, and
stop the operation when the pressure value is outside a normal range, wherein
the stopping of the operation when the pressure value is outside the normal range occurs after a predetermined period of time elapses after the receiving of the pressure value that is outside the normal range.
8 . The control device according to claim 7 , wherein the normal range depends on a target pressure value for liquid in the liquid flow path.
9 . The control device according to claim 7 , wherein the processor is further configured to:
cause a notification to be output when the pressure value is outside the normal range.
10 . The control device according to claim 9 , wherein the notification is an audible sound.
11 . The control device according to claim 9 , wherein the notification is a visual display on a display screen.
12 . The control device according to claim 9 , wherein the notification includes a visual display on a display screen and an audible sound.
13 . A method for a control device of a liquid processing device, the method comprising:
beginning an operation to cause liquid to flow in a liquid flow path to a liquid ejecting head;
receiving a pressure value for liquid in the liquid flow path; and
stopping the operation when the pressure value is outside a normal range, wherein
the stopping of the operation when the pressure value is outside the normal range occurs after a predetermined period of time elapses after the receiving of the pressure value that is outside the normal range.
14 . The method according to claim 13 , further comprising:
causing a notification to be output when the pressure value is outside the normal range.
15 . The method according to claim 14 , wherein the notification includes a visual display on a display screen and an audible sound.
16 . The method according to claim 13 , wherein the normal range depends on a target pressure value for the liquid in the liquid flow path.
