The disclosure describes tecnology for determining print media attributes and adjusting printer parameters using control data embedded (100) in the print media. In particular, a message embedded (100) in the paper conveys information to the printer about paper characteristics (108). A printer, or other device with printing capabilities (e.g., facsimile machine, scanner, copier, etc.) has a sensor (102) for capturing a representation of the message signal and a decoder (104) for decoding printer control information from the message signal. A control unit in the printer interprets this information (108) and uses it to adjust operation of the printer.
摘要:
Read image data is segmented into a plurality of regions in accordance with the attribute of the image data. A region to be printed using a transparent toner is set in accordance with the attributes of the plurality of segmented regions. A preview of the image represented by the image data is displayed, in which the region set to be printed using the transparent toner is distinguished from the remaining regions. An instruction to change the region to be printed using the transparent toner is accepted based on the displayed preview. Print data for the transparent toner to print, using the transparent toner, a region determined based on the change instruction to be printed using the transparent toner is generated.
摘要:
A first information recorder comprises a limit number−of−times of copying information setter for setting information on the limit number−of−times of copying electronic data, a first limit number−of times of copying information update unit for reading out the electronic data from a first information recording medium containing electronic data set with limit number of times of copying information by the limit number−of−times of copying information setter and updating the limit number−of−times of copying information set in the electronic data, and a first transmitter for transmitting electronic data whose limit number−of−times of copying information is updated by the first limit number of times of copying information update unit. A second information recorder comprises a second receiver for receiving electronic data transmitted from the first transmitter, a second limit number−of−times of copying information update unit for reading out the electronic data from a second information containing medium recording the electronic data and updating the limit number−of−times of copying information set in the electronic data, and a second transmitter for transmitting electronic data whose limit number−of−times of copying information is updated by the second limit number−of−times of copying information update unit.
摘要:
An image outputting device capable of printing or displaying/outputting an image and text data automatically and efficiently off-line to a digital copying machine, a printer, a facsimile or a liquid crystal projector. Image discriminating means discriminates whether the data to be printed in a data file, as read out of a memory card by a memory card controller (88), is color or black-and-white image data. If the result of discrimination indicates color image data, print confirming means is provided for the user to confirm whether or not black-and-white data converted from the color image data by color/black-and-white conversion means (90) is to be printed/outputted by black-and-white image forming means.
摘要:
Method and apparatus for altering the operation of printers and scanners to reduce vibration and/or acoustics. The technology involves altering the mode of operation of the printer or scanner to be in either "quick", "quiet" or an intermediate mode. Additionally, means for achieving the different modes of operation are also disclosed.
摘要:
An apparatus for discrimination between a first (308) and a second surface (304) type based on reflectivity has a light source (416) that illuminates on a media surface. A photosensor (420) receives and measures the reflection value from the surface. A first gain element adjusts a voltage from the photosensor and a second gain element adjusts a current measurement supplied to the light source. A subtractor (530) for subtracting the first adjusted voltage (534) and the adjusted measurement (538) are subtracted to provide an output value close to zero with respect to the second surface and near a maximum with respect to the first surface. The adjusted reflection value and a threshold reference value (428) are compared (124) and indicates whether the first surface or the second surface is present.
摘要:
Systems 100 and methods 400 for transmissive optical sensing of media information encoding are disclosed. In addition, print media 108 and methods of making print media are disclosed. One embodiment of an exemplary method, among others, includes, advancing a portion of a print medium 108 through a transmissive sensor assembly 106, the portion of the print medium 108 having a barcode 110, the barcode 110 being minimally transmissive of a set of light wavelengths, and the barcode 110 being encoded with at least one type of information corresponding to the print medium 108; transmitting light at the set of light wavelengths substantially absorbed by the barcode 110 through the print medium 108; and detecting changes in the light transmitted through the print medium 108, the changes being produced by the substantially absorptive barcode 110.
摘要:
In a communication system, a call center is connectable via a communication line to a facsimile apparatus having a printing function. The facsimile apparatus reads ribbon-ID data of an ink ribbon mounted therein, and sends the read ribbon-ID data to the center device. The call center receives the ribbon-ID data from the facsimile apparatus, judges whether or not the ribbon-ID data is valid, and returns a result of the judgment to the facsimile apparatus.
摘要:
A system comprising a sensor and a media handling apparatus including one or more cues perceptible by the sensor when the media is presented to a receiving printing device, whereupon the sensor generates a signal responsive to the one or more cues. The system furthermore featuring a controller coupled to the sensor detects the generated signal and creates a position value for the media presented to the receiving printing device.
