Problems solved by technology

[0006] Although in the prior art, when the developing unit and the developer cartridge are replaced, sometimes the initial installed amount of developer can be initialized through techniques such as circuit fusing of the developing unit or the developer cartridge, but if the developer is directly added to the developer cartridge In the case of the developer, the initial setting of the developer initial loading amount cannot be performed.

Abstract

The invention provides an image formation device capable of setting initial loading quantity of a developer. The image formation device comprises a developing unit, a processing unit, a notification unit and an operation unit. The processing unit comprises a recording part, a calculation part and a judging part. When the developer remnant recorded by the recording part is less than a preset threshold, the judging part judges that the image formation device is in a developer remnant absence state, and updates the developer remnant presence or absence mark recorded by the recording part into a developer remnant absence mark. The notification unit prompts a user with the information of the developer remnant absence state according to the developer remnant absence mark; the operation unit can reset the developer initial loading quantity recorded by the recording part according to the operations of the user, and simultaneously enables the developer remnant equal to be equal to the developer initial loading quantity, clears the developer consumption recorded by the recording part, eliminates the information of the developer remnant absence state prompted by the notification unit, and updates the developer remnant presence or absence mark in the recording part into a developer remnant presence mark.

Description

technical field [0001] The present invention relates to an image forming device, in particular to an image forming device capable of setting the initial loading amount of developer. Background technique [0002] A detachable or integrally formed developing unit is usually provided in an existing image forming device. A developer such as toner or the like is contained in a developer cartridge of the developing unit. During the image forming process, the image forming apparatus will detect the remaining amount of developer in the developing unit, which is also referred to as remaining amount of developer. [0003] In the prior art, the remaining amount of developer in the developing unit is usually detected mechanically, specifically through the contact between the photoelectric reflective sensor and the swing rod connected to the developer detection mechanism. There is a corresponding range of movement, and drives the swing rod connected to the developer detection mechanism...
