摘要： The present disclosure provides an image forming apparatus, a consumable, a consumable chip, and a communication method between the image forming apparatus and the consumable chip. The image forming apparatus comprising: an image forming control unit, configured to send an authentication request to the consumable chip and obtain first time information, generate a first code by performing a calculation using a preset algorithm according to the obtained first time information and pre-stored identity authentication information of the consumable, receive a second code fed back by the consumable chip, wherein the second code is generated by performing a calculation using a preset algorithm according to second time information obtained by the consumable chip and the pre-stored identity authentication information of the consumable, and determine whether the first code and the second code are consistent, to determine whether the consumable meets expectation. The present disclosure generates the first code through the calculation of the image forming control unit, and generates the second code through the calculation of the chip control unit, and determine whether the first code and the second code are consistent, to determine whether the consumable meets expectation, and may improve the security and reliability of authentication.

摘要： The present disclosure provides a security verification method, a consumable chip, a consumable , a consumable chipset. 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.

摘要： The embodiment of the present disclosure provides a method for forming an image, a device, and a computer readable storage medium. The method for forming an image includes: receiving a first image-forming job, and performing a first image-forming operation according to a first recording-medium transport rule; receiving a second image-forming job, and performing a second image-forming operation according to a second recording-medium transport rule. The first image-forming job and the second image-forming job are consecutively outputted image-forming jobs, and recording-medium transport directions of at least one page of the first image-forming job and at least one page of the second image-forming job are different. In the embodiment of the present disclosure, the output paper corresponding to different image-forming jobs is arranged crosswise in different directions by controlling the paper transport direction, so that users can easily distinguish the output paper corresponding to each image forming job.
