Abstract
In some examples, a controller may include a processing resource and a memory resource storing non-transitory machine-readable instructions that are executed to cause the processing resource to direct a clock signal of an imaging device to a fill port via a detection circuit of the imaging device, determine based on a state of a switch included in the detection circuit whether the fill port is open or closed, determine based on the state of the switch indicating the fill port is closed a status of the fill port, and in response to the status of the fill port being closed, determine based on a voltage of the clock signal whether the fill port is connected to a colorant container.
Claims15
A controller, comprising:
- a processing resource;
- and
- a memory resource storing non-transitory machine-readable instructions that are executed to cause the processing resource to:
- direct a clock signal of an imaging device to a fill port via a detection circuit of the imaging device;
- determine, based on a state of a switch included in the detection circuit, whether the fill port is open or closed;
- determine, based on the state of the switch indicating the fill port is closed, a status of the fill port;
- and
- in response to the status of the fill port being closed, determine based on a voltage of the clock signal whether the fill port is connected to a colorant container.
A device, comprising:
- a fill port cover corresponding to a fill port of the device;
- a detection circuit including a switch, wherein the switch is electrically connected to the fill port;
- and
- a controller to:
- direct a clock signal of the device to the fill port via the detection circuit;
- determine, based on a state of the switch, whether the fill port is open or closed;
- determine, based on the state of the switch indicating the fill port is closed, a status of the fill port;
- in response to the status of the fill port being closed, determine the fill port is connected to a colorant container in response to a voltage of the clock signal being a first voltage;
- and
- in response to the status of the fill port being closed, determine the fill port is connected to the fill port cover in response to the voltage of the clock signal being a second voltage.
An imaging device, comprising:
- a plurality of fill ports, wherein each fill port of the plurality of fill ports includes a respective fill port cover;
- a detection circuit, wherein the detection circuit includes:
- a plurality of switches, wherein each respective switch of the plurality of switches is electrically connected to respective fill ports of the plurality of fill ports;
- and
- a pull-down resistor;
- a controller to perform a detection process, wherein the controller performs the detection process by:
- connecting a clock signal of the imaging device to a first fill port of the plurality of fill ports via the detection circuit;
- determining, based on a state of a first switch of the plurality of switches that is electrically connected to the first fill port, whether the first fill port is open or closed;
- in response to the first fill port being closed, determining the first fill port is connected to a colorant container in response to a voltage of the clock signal being a first voltage;
- and
- in response to the status of the first fill port being closed, determining the first fill port is connected to a fill port cover in response to the voltage of the clock signal being a second voltage.
