摘要:
A method generates a test pattern on an image receiving member that is less perceptible to human observation, but still detectable by an imaging device within a printer. A method implemented in the printer analyzes image data of the dashes in the test pattern that were randomly distributed in the process direction within an area of the image receiving member to identify positions for printheads in the printer and detect missing inkjets in the printheads.

A method enables an operator to detect misalignment of printheads that eject clear ink in an inkjet printer. The method prints a first test pattern with a first color of ink and then prints a second test pattern of clear ink on top of the first test pattern. The ink of the first and the second test patterns is then spread to enable the clear ink to be dispersed in interstitial spaces in the ink of the first color. An operator is then able to detect the spatial relationship of predetermined marks in the second test pattern to predetermined marks in the first test pattern. The predetermined marks of the first and the second test patterns are arranged to enable an operator to detect a misalignment distance and the inkjet printer uses the misalignment distance entered by the operator to adjust the alignment of the printheads that eject clear ink.

A critical parameter/requirements management process model for managing a development program for a product and an associated product structure-driven critical parameter/requirements management tool and environment is provided. In one embodiment, the process includes a product structure classification scheme, a parameter/requirements classification scheme, a parameter/requirements process and maturity model, and in-process and requirements conformance views. In one embodiment, the tool includes a user interface layer, a business layer, a data layer, and a database. The user interface layer may include a product structure feature group, an add/edit/link feature group, a manage maturity feature group, and a manage conformance feature group. The tool may be implemented as a web server accessible to user workstations operating as thin clients. The tool may be integrated with one or more other product development tools, such as a document-driven requirements management, configuration management, manufacturing/production control system, problem management, and phased product delivery process tools.

摘要:
A pre-heater system and adapted to be used on an electrostatic marking apparatus for improving gloss on media having marking thereon at a location in the apparatus prior to a conventional fuser roll assembly or station, the system including a primary heater adapted to blow pressurized hot air into a surface of an image receiving media in order to substantially dispense hot air throughout an entire paper or media surface; and a preheat media transport for transporting media from the location in the apparatus prior to the conventional fuser roll assembly or station through the primary heater, the preheat media transport includes means for maintaining the preheat media transport at a substantially uniform predefined temperature.
摘要:
An apparatus for stacking, registering and attaching one or multiple sets of electrophotographic printing machine output. The copy sheets are discharged from the machine and fall into an inclined compiling tray and are longitudinally registered by flexible, endless belts contacting the top surface of each sheet. Each sheet is then laterally shifted by a tamping mechanism which has upwardly flared baffle to corrugate the sheet as it is shifted to increase the sheet beam strength and facilitate easier and more complete registration. The discharge nip assembly which includes the flexible belts is vertically adjustable either based on discharged sheet count or in response to feedback from a stack height sensor so as to maintain optimum contact by the endless registration belt and allow for high capacity compiling. The compiling tray can also be adjustable. Once a complete set of sheets has been discharged and fully registered the stack is then attached by stapling or other means and is discharged from the compiling tray. The discharge nip and compiling tray then return to their home position to accept the next set of copy sheets.
摘要:
A plural function sheet interconnect module for serially connecting plural multiple bins printed sheets job separating units, such as mailbox modules, with the output of a printer for feeding printed sheets jobs into selected bins. The printer also has a alternate variably occurring output of purge sheets designated for purging, which purge sheets are variably intermixed with the printed sheets jobs. The interconnect module has a sheet bypass transport for feeding the sheets on from one mailbox unit on to another. The interconnect module also has an integral purge tray for collecting the purge sheets and providing for their removal. The interconnect module further has a selectable shared sheet gating system for gating the printed sheets jobs into the sheet bypass transport and gating the purge sheets into the integral purge tray. The integral purge tray underlies the sheet bypass transport and is pivotably openable for the removal of purge sheets therefrom.
摘要:
In a copier or printer producing a sequential stream of sheets with limited time therebetween, and with compiling and finishing of those output sheets on-line while subsequent sheets are being printed, a non-slip sheet feeder normally feeding copy sheets downstream to the compiler is selectably intermittently temporarily stopped holding the lead edge area of the first copy sheet for the next set to be finished so that continued feeding of the trail end of the same sheet by a relatively closely spaced upstream feeder buckles that sheet into a buckle chamber assisted by a buckle inducing arcuate baffle extending from the other side of the sheet path. The next printed sheet is fed normally while the buckled first sheet is positively held out of its way. When the second sheet reaches the downstream feeder, it restarts to positively feed both sheets downstream to the compiler, together, but overlapped by a preset amount for registration stacking. A substantial increase is provided in the time for the preceding copy sheets to be operated on in the compiler. A plural sheet collection point may also be provided by this sheet buffering system.
