A liquid ejecting apparatus includes a liquid ejecting head that ejects a liquid accommodated in a liquid container, a detection unit that detects a remaining amount of the liquid accommodated in the liquid container, and a control unit that operates in a normal mode and a special mode. In the normal mode, the control unit prohibits ejection of the liquid from the liquid ejecting head when the detection unit has detected that the remaining amount of the liquid accommodated in the liquid container has become smaller than a predetermined threshold value. In the second mode, the control unit allows ejection of the liquid from the liquid ejecting head with an instruction from a user as a requirement when the detection unit has detected that the remaining amount of the liquid accommodated in the liquid container has become smaller than the predetermined threshold value.

A liquid ejecting apparatus includes a liquid container and a control unit. The liquid container has an upper limit mark. The upper limit mark is arranged so that in a first case where an entire amount of liquid stored in a refilling container is injected into a storage portion when a notification unit notifies of a first state, a liquid level of the liquid in the storage portion is located between an inlet port and the upper limit mark, and in a second case where the entire amount of liquid stored in the refilling container is injected into the storage portion when the notification unit notifies of a second state, the liquid level overlaps with the upper limit mark.

An image forming apparatus, having a cartridge detachably attached to the image forming apparatus and including a first compartment configured to store a colorant, a container configured to be connected with the cartridge and including a second compartment configured to store the colorant flowing from the cartridge, and a display configured to display a first object indicating a first remainder amount and a second object indicating a second remainder amount in a single screen, is provided. The first remainder amount is a remainder amount of the colorant stored in the first compartment, and the second remainder amount is a remainder amount of the colorant stored in the second compartment.

An image forming apparatus includes an image forming section, a main replenishing section, an auxiliary replenishing section, and a controller. The image forming section forms an image on a recording medium using a consumable. The main replenishing section retains the consumable therein. The auxiliary replenishing section is replenished with the consumable from the main replenishing section and replenishes the consumable to the image forming section. The controller controls an image forming speed for forming the image on the recording medium. The controller lowers the image forming speed below a normal speed when a main residual amount corresponding to a remaining amount of the consumable retained in the main replenishing section is no greater than a specified value.

In an image-recording device, a mount body detachably holds a cartridge. The cartridge has a first chamber configured to store consumable therein. A tank is in communication with the cartridge, and the tank has a second chamber. Consumable in the first chamber is capable of moving into the second chamber. A controller determines whether a residual quantity of consumable stored in the first chamber of the cartridge held by the mount body is lower than or equal to a prescribed threshold. The controller expands, when a specific condition is satisfied, a maximum quantity of consumable up to which consumable is capable of being stored in the second chamber. The specific condition includes a first condition that the residual quantity of consumable stored in the first chamber is higher than the prescribed threshold, and a second condition that information notifying that the cartridge is to be replaced is received.

A liquid discharge apparatus includes a case receiving a cartridge, a tank, a head, and a controller to: when the cartridge is installed in the case, calculate an outflow amount Qc based on heights Hc, Hs and flow path resistances; read the amounts Vc, Vs from a memory; subtract the outflow amount Qc from the read liquid amount Vc to calculate new liquid amount Vc; add the outflow amount Qc to the read liquid amount Vs to calculate new liquid amount Vs; store the calculated liquid amounts Vc, Vs in the memory; after a time period from at the time the calculated liquid amounts Vc, Vs stored elapses, again calculate the outflow amount Qc and the liquid amounts Vc, Vs and store the calculated liquid amounts Vc, Vs in the memory.

An image forming apparatus, having a first container with a first compartment, a second container with a second compartment, a recorder, a display, and a controller, is provided. The controller controls the display to display a first screen and a second screen. The first screen contains a first object having a form that reflects an amount of a colorant in the first compartment and a second object having a form that reflects an amount of the colorant in the second compartment. The second screen contains a third object having a form that reflects one of the amount of the colorant in the first compartment, the amount of the colorant in the second compartment, and a total amount of the colorant in the first compartment and the second compartment.

An information processing device may notify first notification information in a case where a remaining amount of colorant in a first-type printer reaches a first remaining amount, notify second notification information in a case where the remaining amount reaches an unprintable remaining amount, notify third notification information in a case where a remaining amount of colorant in a second-type printer reaches a second remaining amount, and notify fourth notification information in a case where the remaining amount reaches the unprintable remaining amount. The first-type printer may include a tank for storing colorant supplied from a first cartridge to a first print executing unit. The first remaining amount may be a remaining amount in a state where the colorant does not remain in the first cartridge but remains in the tank. The second-type printer may include a second print executing unit and may not include a tank.

In an image forming apparatus, a controller is configured to: obtain conformance information, for each of at least one color, representing each container conforming to the image forming apparatus; obtain usage information related to a relationship between the total number of recording media on which images are formed within a past particular period and a total amount of a colorant used within the past particular period; based on the obtained usage information, calculate a first initial formable number for each of the at least one color which represents the total number of recording media on which images are respectively formable using the colorant with a particular initial containing amount; and display a detailed-information screen containing conformance detailed information for each of the at least one color. The obtained conformance information and the first initial formable number are associated with each other in the conformance detailed information.

When a first fluid supply of a fluid-ejection device is empty and a second fluid supply of the device has a non-empty fluid amount less than a threshold, the device performs an action related to the second fluid supply. After the action has been performed and both the first and second fluid supplies have been replaced, the device primes the first and second fluid supplies. The action can include emptying the second fluid supply, and then messaging that both the fluid supplies require replacement. The action can include messaging that both fluid supplies require replacement although the second fluid supply is not empty. The action can include not messaging even that the first fluid supply requires replacement until the second fluid supply also becomes empty.
