摘要:
An image forming apparatus including a replaceable unit to participate in an image forming job, and a consumer replaceable unit monitor (CRUM) unit mountable to the replaceable unit.
摘要:
A replaceable unit to participate in an image forming job of an image forming apparatus includes a storage unit to store therein a driving condition corresponding to an operation environment, a detecting unit to monitor the operation environment, a controlling unit to detect a corresponding driving condition from the storage unit if the detecting unit detects the driving environment, and an interface unit to provide a main body of the image forming apparatus with the detected corresponding driving condition. Accordingly, the replaceable unit can be driven under optimum driving conditions.

摘要:
A developer of an image-forming apparatus includes a photoconductor, a housing comprising a waste toner container in which waste toner removed from the photoconductor is contained, and a recessed portion depressed downwardly in a center portion of an upper wall of the waste toner container, the center portion corresponding to a center portion of the photoconductor in a lengthwise direction to move toner away from the center portion.
摘要:
A chip mountable on a replaceable unit used in an image forming job is disclosed. The chip includes a central processing unit (CPU) to perform at least one of authentication and cryptographic data communication with a main body of the image forming apparatus using an operating system (OS) of the CPU which operates separately from an OS of the image forming apparatus. With the use of such a configuration, security for a unit in which the chip is mounted can thereby be reinforced.
摘要:
A chip mountable on a customer replaceable unit monitoring memory (CRUM) unit used in an image forming job includes a central processing unit (CPU) with its own operating system (OS), which operates separately from an OS of the image forming apparatus, to perform authentication communication with a main body of the image forming apparatus using the OS of the CPU. The security of a unit on which the chip is mounted can thereby be reinforced and random changes of data of the unit can be prevented.

A chip mountable on a customer replaceable unit monitoring memory (CRUM) unit used in an image forming job includes a central processing unit (CPU) with an operating system (OS) thereof, which is separate from an OS of the image forming apparatus, to perform at least one of authentication and cryptographic data communication with a main body of an image forming apparatus by executing one cryptographic algorithm corresponding to a set state from among a plurality of pre-provided cryptographic algorithms, using the OS thereof. The security of a unit on which the chip is mounted can thereby be reinforced and random changes of data of the unit can be prevented.
