摘要： Blanket replacement systems and methods useable with an image forming apparatus are provided herein. The blanket replacement system removes the blanket from the image transfer member and attaches the blanket to the image transfer member. The blanket replacement system includes a frame member, an engagement motor, and a rotation motor. The frame member holds a blanket having a lead edge portion on one edge and a trail edge portion on an opposing edge. The frame member further includes a lead edge clamp unit and a trail edge clamp unit that holds the lead edge and trail edge portions of the blanket and engages with an image transfer member. The engagement motor engages with the frame member and moves the frame member laterally in relation to the engagement motor. The rotation motor is connected to the engagement motor and rotates the engagement motor and the frame member.

摘要： A computer-implemented method of controlling the creation of a printed document includes the steps of: retrieving print information for generating a print job, said print information specifying characteristics of a document to be printed; retrieving at least one attribute of a print finishing device, said attribute defining a constraint imposed on the print job for printing said document, when the printed document is processed in said print finishing device; and generating a print job based on said print information and said constraint. In one example, retrieving said at least one attribute of a print finishing device includes establishing a communication link to said print finishing device and prompting the print finishing device to transmit the at least one attribute. Said communication link can be established and used on-line at the time of generating the print job or in advance.
