PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18210152 titled 'PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes a cartridge used for replenishing developer in a device. The cartridge has a receptacle with a replenishment port and a transport region. The developer is replenished through the port and transported in a specific direction.

The cartridge has a receptacle with a replenishment port for replenishing developer.
The developer is transported in a specific direction in a transport region located lower than the replenishment port.
The receptacle has a first filter and a second filter, which restrict the passage of developer but allow the passage of air.
The first filter is located downstream of the replenishment port, while the second filter is located upstream of the replenishment port.
Either the first filter or the second filter is positioned higher than the transport region in the direction of gravity.

Potential applications of this technology:

This cartridge design can be used in various devices that require the replenishment of developer, such as printers, photocopiers, or fax machines.
It can be applied in both consumer and industrial settings where developer replenishment is necessary.

Problems solved by this technology:

The first and second filters prevent the developer from flowing freely, ensuring controlled replenishment and preventing any potential blockages or contamination.
The transport region being located lower than the replenishment port allows for gravity-assisted movement of the developer, facilitating its efficient transport.

Benefits of this technology:

The use of filters ensures the quality and purity of the developer, preventing any unwanted particles or impurities from entering the system.
The gravity-assisted transport of the developer simplifies the replenishment process and reduces the need for additional mechanisms or pumps.
The cartridge design provides a reliable and efficient method for replenishing developer, enhancing the overall performance and longevity of the device.

Original Abstract Submitted

A cartridge is used, which has a receptacle with a replenishment port from which a developer is replenished and which is configured to receive the developer replenished from the replenishment port. The receptacle has a transport region that is located lower than the replenishment port in the direction of gravity, where the received developer is transported in a transport direction. The receptacle is provided with a first filter and a second filter downstream and upstream of the replenishment port respectively in the transport direction. The first filter and second filter restrict passage of the developer while allowing passage of air. The first filter or the second filter is located higher than the transport region in the direction of gravity.
