A drum cartridge includes a frame on which a toner cartridge is attachable, a photosensitive drum, and a drum memory. The drum cartridge relays information stored in the toner memory to the image forming apparatus when the toner cartridge is attached to the frame.

Drum cartridge and image forming apparatus

An image forming apparatus, including: a housing; a photoconductor; a developing unit configured to form a developer image on the photoconductor; a developer cartridge storing developer, the cartridge being removably mountable on the housing, a supplier configured to supply the developer from the developer cartridge to the developing unit; and a controller configured to execute a first printing process of forming a developer image by use of the developer supplied from the developer cartridge, when the developer cartridge is being mounted on the housing, and a second printing process of forming a developer image by use of the developer remaining in the developing unit, when a usage amount of the developing unit is not less than a predetermined value and the developer cartridge is not being mounted on the housing, wherein the controller does not execute the second printing process when the usage amount is less than the predetermined value.

Image forming apparatus and control method thereof

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.

Image forming apparatus capable of determining whether toner cartridge is attached to appropriate slot provided in main casing

A recording apparatus includes: a first housing; a second housing pivotable about a shaft relative to the first housing between a close position and a distant position; and a tank mount portion provided in the second housing such that a mounting direction of a tank with respect to the tank mount portion in a state in which the second housing is at the distant position has a downward component in a vertical direction. The tank mount portion includes a resistance applying mechanism which applies a resistance force to the tank in a state in which at least a part of the tank is inserted into the tank mount portion when the second housing is at the distant position.

Recording apparatus

An image forming apparatus includes a controller configured to, each time a development roller of a developing device rotates by a particular rotational amount, increment a counter value stored in a storage, calculate a remaining amount of developer in the developing device, when the counter value is less than a first value, setting a remaining amount threshold to a first threshold, whereas, when the counter value is equal to or more than a second value, setting the remaining amount threshold to a second threshold, the second value being equal to or more than the first value, the second threshold being less than the first threshold, and when the calculated remaining amount is less than the set remaining amount threshold, control a transporter to transport developer stored in a developer box to the developing device.

Image forming apparatus, and method and computer-readable medium therefor

A recording apparatus includes a controller configured to: decrease the number of recording pages which is stored in a storage in response to completion of recording on a recording medium on a page-by-page basis; increase the number of recording pages in response to an increase in an amount of image data in the storage; determine whether the number of recording pages is greater than or equal to a first number; control a drive source and a recording device to convey the recording medium at a first speed and perform recording when the number of recording pages is less than the first number; and control the drive source and the recording device to convey the recording medium at a second speed greater than the first speed and perform the recording when the number of recording pages is greater than or equal to the first number.

Recording apparatus capable of switching recording speed and non-transitory storage medium storing instructions executable by the same

A cartridge accommodating apparatus includes: a cartridge accommodating section accommodating a cartridge which includes a liquid accommodating section, a liquid lead-out channel, a first blocking member blocking a first portion of the liquid lead-out channel, and a second blocking member blocking a second portion between the first portion and the liquid accommodating section; a hollow tube introducing liquid in the liquid lead-out channel into inside of the hollow tube; a moving mechanism moving the hollow tube between a first position at which a tip portion of the hollow tube is located outside the liquid lead-out channel and a second position at which the tip portion of the hollow tube has entered inside the liquid lead-out channel; a driving source; a driving force transmitting mechanism transmitting driving force of the driving source to the moving mechanism; and a driving source controller controlling driving speed of the driving source.
