A low cost, high speed, high resolution laser printer method and apparatus for re-writable media is presented. A method for finishing of printed sheets into booklets is described. Novel mechanical operations permit the manufacture of a very low-cost, off-line booklet maker for use with desktop laser and ink jet printers. The technology can scale to medium-speed, in-line booklet manufacture. The method is novel because most of the finishing operations are performed on a sheet-by-sheet basis using precision paper positioning and a transverse tool carrier that cuts, scores, folds, punches, and staples the sheets. To form a finished saddle-stitched booklet, each sheet is cut to length determined by its sequence in the booklet and paper thickness, scored, punched (if required), folded, accumulated in a stack, and stapled. The sheet-wise method allows finishing operations to be done with low-cost tools and low actuation forces.

A print head is positioned downstream of the roller assembly for carrying out a printing operation on the sheets of print media. An adhesive application mechanism is positioned downstream of the print head and includes first and second aligned adhesive applicators that are positioned on opposite sides of the feed path and are configured to apply adhesive simultaneously to the sheets of media as the sheets pass between the applicators along the feed path, such that the sheets each have aligned strips of adhesive on respective sides. A support structure positioned downstream of the adhesive application mechanism defines a floor onto which sheets to be bound are conveyed and a wall that extends from the floor to define a stop for the sheets that are fed onto the floor. A binding mechanism is arranged on the support structure and is displaceable with respect to the support structure to act on each sheet fed into the support structure such that the sheets are adhered together with the strips of adhesive.

By controlling the recording position of images on the cover sheet by the image recording section based on the thickness information of the bundle of sheets, image recording at the appropriate position has been made possible irrespective at the amount of trimming of the cover sheet that is trimmed to an appropriate length in accordance with the thickness of the bundle of sheets to be wrapped and bound with the cover sheet.

A print server checks a job ticket for a print job to be processed. When a method of printing set in the printing attributes of the job ticket is case binding, a first thickness of a bookblock is calculated using the paper type set in the printing attributes. The print server calculates a second thickness of a bookblock using the paper type after a change. The print server changes the paper type set in the job ticket when the difference between the first thickness and the second thickness is within a permissible range.

A spine formation device includes a sheet conveyer, a clamping unit disposed downstream from the sheet conveyer in a sheet conveyance direction, for squeezing a folded portion of a bundle of folded sheets, a contact member against which the folded portion of the bundle is pressed, disposed downstream from the clamping unit, and a controller to cause the bundle of folded sheets to bulge by stopping the sheet conveyer after the bundle of folded sheets is transported a predetermined conveyance distance from a contact position between the contact member and the folded portion of the bundle and to cause the clamping unit to squeeze a bulging portion of the bundle created between the sheet conveyer and the contact member with the folded portion pressed against the contact member. The predetermined distance is set in accordance with a predetermined sheet-related variable.

A bookbinding device receives a sheet on which an image is formed from an image forming apparatus. In the bookbinding device, a punching unit performs a punching process on a sheet; an aligning unit aligns a plurality of sheets on which holes are punched; and a ring binding unit mounts, in the holes of the sheets aligned by the aligning unit, a ring-shaped binding tool to create a booklet. A prohibiting unit, if a sheet received from the image forming apparatus is a punched sheet having a hole thereon, causes the punching unit not to perform the punching process on the punched sheet.

In binding a cover sheet together with a sheet bundle, ever-accurate spine-creasing irrespective of bundle thickness is made possible. A sheet stacker stacks sheets into bundles, an adhesive applicator applies adhesive to a spine part of the sheet bundles, and a cover-sheet binder binds cover sheets together with the spine parts. The cover-sheet binder is constituted from a left-and-right pair of spine-creasing press members arranged free to shift between standby and spine-creasing positions; a shifter that reciprocates the spine-creasing press members between the standby and spine-creasing positions; and a controller. The controller functions to vary, in accordance with sheet bundle thickness, any of: (1) the standby position of the press members; (2) the start time of an operation whereby the press members are shifted from the standby to the spine-creasing position; or (3) the traveling speed of the press members in shifting from the standby to the spine-creasing position.
