An apparatus is disclosed that automatically generates a set of recommended printer settingsfor a print jobsubmitted to a printer. The apparatus comprises at least one processor which executes computer program code from at least one memory, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to: receive a submitted print job for a printer, the submitted print job including content to be printed by the printer and a set of user input printer settings for the printer; analyze the content to be printed by the printer; designate a classification for the submitted print job based on said analysis; obtain historical data from a knowledge database, the historical data being related to prior print jobs run on the printer and indicating printer settings used when running the prior print jobs on the printer; and output a set of recommended printer settings based at least in part on one or more of the received print job, the designated classification and the obtained historical data.

System and method for optimizing a printer setup

A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes tracking a machine state of the MFD, predicting a potential defect based on a determination that the machine state is associated with a defect class of a plurality of different defect classes, determining a maintenance routine associated with the defect class, and executing the maintenance routine to prevent the potential defect.

Examples of the preferred embodiments use an ink quantity metric (e.g., lightness L*, darkness, image density, line width) of printed content to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor (e.g., spectrometer) may measure the ink quantity metric of the current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.

Method for monitoring a fountain solution layer in an image forming device

According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution using a hot wire anemometer. Fountain solution thickness is measured using the flow rate of vaporized fountain solution and comparing to baseline air only flow rate. The vaporized measurement is correlated with the baseline utilizing specific heat, density and enthalpy values and keeping velocity of fluid constant. Changes in the measurement will then be related to the specific heat, density and enthalpy. Density can be back calculated to yield volume and knowing the area of the image being printed give a real time thickness value.

Apparatuses include a conveyor moving in a processing direction, a print head positioned adjacent the conveyor, a light source positioned adjacent a first side of the conveyor, a movable mirror positioned adjacent a second side of the conveyor, that is across the conveyor from the first side of the conveyor, a fixed mirror positioned adjacent the first side of the conveyor (the fixed mirror is between the light source and the print head), and a light sensor position adjacent the second side of the conveyor. The light sensor is between the movable mirror and the print head. The light source outputs light to the movable mirror across the conveyor, the movable mirror directs the light back across the conveyor to the fixed mirror, and the fixed mirror directs the light again across the conveyor to the light sensor.

A method and apparatus for verifying content of partially printed purge sheets of confidential documents just after shredding the purge sheets but before the individual strands become separated and disassociated is disclosed. The purge sheet can be passed through a single nip paper transport to a shredder and then to a scanner in order to verify the content of the purge sheets. The scanned document can also be stored on a DFE (digital front end) disk, which provides visual documentation of, purge sheet destruction and can be utilized for later reconciliation. The individual strands of the purge sheet(s) can be separated and disassociated to a container in order to ensure destruction. A small electronic controller board associated with the scanner provides function control and communications to the DFE.

Scanning shredder method and apparatus

A method maintains an environment within an interior of a sheet feeder during dead-cycling of an image forming device to which the sheet feeder is operatively connected. The method jets pulses of air into the interior of the sheet feeder that houses two or more pieces of media therein while the image forming device is dead-cycling. By the method, the attractive forces between two pieces of adjacent media. In a stack are reduced or minimized, and feeding of multiple sheets can be reduced or eliminated.
