摘要:
In a first image formation mode, an image is formed with a first development contrast C1 and a specific dot pattern is formed with a second development contrast C2, which is lower than the first development contrast C1; in a second image formation mode, an image is formed with a third development contrast C3 and a specific dot pattern is formed with a fourth development contrast C4, which is lower than the third development contrast C3; and when ΔC1 (=C2/C1) denotes a ratio between the second development contrast C2 and the first development contrast C1, and ΔC2 (=C4/C3) denotes a ratio between the fourth development contrast C4 and the third development contrast C3, ΔC2

In one example, an imaging supply includes a container to contain an imaging material, a first memory on the container, and a second memory on the container different from the first memory. The first memory stores an indication that signed data is stored in the second memory and the second memory stores a digital signature to authenticate the imaging supply to a printer or an indication that unsigned data is stored in the second memory and the second memory stores consumables management data or an indication that no data is stored in the second memory.

A document management system includes a document operation log recording unit configured to record as an operation log a history of operations for each document managed by the document management system, a print log collecting unit configured to collect a print log indicating a history of printing executed by a printing device, a log comparison unit configured to compare the operation log recorded by the document operation log recording unit with the print log collected by the print log collecting unit, a document printing determination unit configured to determine, based on a result of comparison by the log comparison unit, whether each document managed by the document management system was printed, and a document print information updating unit configured to update, based on a result of determination by the document printing determination unit, print information of each document managed by the document management system.
摘要:
This invention provides an image forming apparatus which prevents unauthorized printing without impairing the user's convenience. To accomplish this, upon reception of the print job, the image forming apparatus determines if the print job is a storage target job. If the print job is a storage target job, the image forming apparatus temporarily stores the print job in a memory without starting printing. The image forming apparatus creates and transmits a URL which is required to access a Web server included in the self apparatus and is uniquely assigned to the print job, to the external apparatus which transmitted the print job. After that, when an access to the URL is generated, the image forming apparatus starts printing the temporarily stored print job.
摘要:
An image processing device comprises an image data input means 2, an image data storage means 12 for storing the image data being input, an image data processing means 6 having multiple processing modes for outputting the stored image data, and a image data erasing means for erasing the image data stored in the storage means 12. The device further comprises erase count control means 8, 14 for controlling the number of times for erasing image data capable of having the number of times of erase set arbitrarily according to the security level required for each mode, and capable of having the set number of times of erase changed in mid-flow. Confidentiality is protected by performing erase operations repeatedly to the region storing the unnecessary image data according to the security level.
摘要:
A print record management device includes a comparison unit that compares print image data produced on the basis of stored document data with the stored document data, and a determination unit that determines, from a result of the comparison, which of the print image data and association data showing association with the stored document data is to be stored as record data for enabling reproduction of printing processing in relation to the print image data.
摘要:
Information identifying a user who made an instruction to send a document from a personal computer (PC) to an image forming apparatus and to store the document in the image forming apparatus, that is, a user who caused the risk of information leakage to increase could not be identified. Code image data which includes information identifying the user who made the storage instruction and information identifying another user who made a print instruction is printed together with print data.
