According to an embodiment, a printer includes a printer unit configured to print images on paper, a connector connectable to a detachable storage medium, and a controller. The controller is configured to acquire time information from the storage medium when the storage medium is connected to connector, and then store output information in the storage medium. The output information includes device information related to a print function of the printer unit and the acquired timing information in association with each other. The printer may lack an internal clock yet still output information associated with time information.

The present disclosure provides a security verification method, a consumable chip, a consumable chipset, a consumable. The method includes obtaining a preset dynamic parameter configured to determine an authentication sequence; determining authentication sequence data corresponding to a plurality of authentication events according to the preset dynamic parameter; and executing at least one of the plurality of authentication events according to the authentication sequence data and feeding back an authentication result of at least one of the plurality of authentication events to the image forming apparatus. The authentication result is configured to determine whether a consumable corresponding to at least one of consumable chips in the consumable chipset satisfies a preset image forming requirement. The present disclosure effectively avoids the problem of damaging the image forming apparatus and affecting printing quality caused by the use of consumables provided by third parties that do not satisfy requirements.

The present disclosure provides a cartridge test device, a cartridge component, and a cartridge component test method. The cartridge component (10) includes a cartridge package (12) and cartridges (11) accommodated in the cartridge package (12), the cartridge package (12) is provided with openings (121) corresponding to the cartridges (11). The cartridge test device (20) includes a device main body (21), a data transmission apparatus (22) mounted on the device main body (21) and in either or both of electrical connection and signal connection with the device main body (21), and test heads (23). The test heads (23) are connected to the device main body (21) and are in either or both of electrical connection and signal connection with the data transmission apparatus (22). The openings (121) are configured to allow the test heads (23) to be in either or both of electrical connection and signal connection with corresponding cartridges (11).

The present disclosure provides a consumable, a consumable chip, and a communication method between the image forming apparatus and the consumable chip. The consumable chip is capable of being installed on a consumable, and the consumable is capable of being detachably installed on an image forming apparatus. The consumable chip includes a storage unit and a chip control unit. The storage unit is configured to store identity authentication information of the consumable. The chip control unit is configured to receive an authentication request sent by the image forming apparatus and obtain second time information, generate a second code by performing a calculation using a preset algorithm according to the obtained second time information and the pre-stored identity authentication information of the consumable, and send the second code to the image forming apparatus. The second code is configured to determine whether the consumable meets expectation.

A remanufactured ink cartridge and an electronic patch are provided in the present disclosure. A remanufactured ink cartridge includes an ink accommodation container; an original chip disposed at an outer side of the ink accommodation container, where the original chip includes a first memory; and an electronic patch disposed between the original chip and the ink accommodation container. The electronic patch includes a second memory and first programming terminals electronically connected to the second memory; the first programming terminals are configured to program data for repairing to the second memory; the data for repairing is configured to repair or replace at least a portion of data in the first memory; and at least one of the first programming terminals is exposed outside the original chip.

A ROM unit mounted to a bottle has a plurality of terminal plates on the front end surface of the ROM unit. The ROM unit is movable in a direction orthogonal to a bottle axis Ax, and can be positioned at a retreat position where an interference with a contamination preventing eaves is avoided, and a contact position projected more front than the retreat position. The terminal plates can be electrically contacted with reservoir terminals when positioning at the contact position.

A print supply, the print supply containing a print material and to connect to a printing device to provide the print material to the printing device that includes a container to maintain the print material, an integrated circuit coupled to the box to interface electrically with the printing device, and a load cell communicatively coupled to the integrated circuit to detect a weight of the print liquid supply.

A print component integrated circuitry package includes a number of temperature sensors where each of the plurality of the temperature sensors is disposed in a corresponding temperature region of an integrated circuitry. In an example, an analog sense bus conductively connects to all of the plurality of temperature sensors and an external sensor pad that is to connect to a corresponding print controller contact.

A logic circuitry package for a replaceable print apparatus component includes an interface and at least one logic circuit. The at least one logic circuit is configured to respond to communications sent to a first address via the interface and respond to communications sent to a second address via the interface. The at least one logic circuit is configured to in response to a hibernate command sent to the first address, respond to communications sent to the second address.
