摘要： An image forming device includes a first supplier configured to supply a long recording medium, an image forming engine configured to form an image on the recording medium supplied from the first supplier using a color material supplied from a color reservoir, a remaining amount output device configured to output a signal indicating a remaining amount of the color material. The image forming device derives a length of a recording medium on which images can be formed until a color material in the color reservoir runs out, and displays the length of the recording medium on which the images can be formed derived in the deriving on a display.

摘要： The method includes determining, by using a first information processing device, whether a cartridge mounted in the specified image forming apparatus needs replacing. The method further includes attaching a label to the newly shipped cartridge capable of using in each of the plurality of image forming apparatuses or to a packing box packing the newly shipped cartridge. The label indicates specific information associated with identification information of the specified image forming apparatus in which the determining determines that the cartridge needs replacing. The specific information is retrieved from a database in which the identification information is associated with the specific information. The identification information identifies the each of the plurality of image forming apparatuses. The specific information specifies the each of the plurality of image forming apparatuses.

摘要： An image forming apparatus includes: a main body; a drum cartridge and a toner cartridge those attachable to the main body; a main memory; and a controller. The controller is configured to perform: determining a number of sheets printable using the toner cartridge attached to the main body; determining a number of sheets printable using the drum cartridge attached to the main body; determining a number of sheets printable using a new toner cartridge; and when determining that a sum of the number of sheets printable using the toner cartridge attached to the main body and the number of sheets printable using a new toner cartridge is greater than or equal to the number of sheets printable using the drum cartridge attached to the main body, transmitting to a server a signal for ordering a new drum cartridge together with a new toner cartridge.

摘要： An image forming apparatus includes: a drum cartridge to which one of a first toner cartridge and a second toner cartridge is attachable; a frame including a first slot and a second slot; and a controller including a control memory and a processor. The drum cartridge to which the one of the first toner cartridge and the second toner cartridges is attached is attachable to one of the first slot and the second slot. The control memory stores first color information allocated to the first slot, and second color information allocated to the second slot. In a state where the drum cartridge is attached to one of the first slot and the second slot and when the drum memory does not store any color information, the processor is configured to perform: writing, into the drum memory, one of the first color information and the second color information which is appropriate.
