Method to automate a transfer assist blade device timing adjustment

Номер: US20120106992A1
Автор: Kenneth Wayne Luff, Thomas Edward Higgins
Принадлежит: Xerox Corp

When calibrating a transfer assist blade (TAB) in a printer, toner patches are formed on a photoreceptor belt in the printer at locations between sheets of paper. The TAB is partially deployed between paper sheets to pick up toner, and then deployed normally or with a delay to mark the back sides of the sheets. A processor evaluates distances between TAB touchdown and liftoff points and leading and trailing edges of the sheets, and calibrates the TAB to optimize the TAB timing. Additionally, test prints can be generated, each having slightly varied TAB calibration settings that are stored in a non-volatile memory (NVM) table. A user enters an identification number for a test print with the best calibration settings. The processor looks up calibration settings corresponding to the entered identification number and moves NVM settings from the table into operational locations in the system NVM to calibrate the printer.

Two-component developer in an electrophotographic (EP) printer is replenished. Image data are received and a corresponding latent image is produced. Toner is supplied to the latent image by bringing developer containing toner particles and carrier particles into proximity with the latent image on the photoreceptor using a toning member, so that toner particles are removed from the developer to produce depleted developer. The depleted developer is transported to a return channel, along which it is moved at a channel speed. A processor automatically estimates, as a replenishment amount of toner to be added to the return channel, the amount of toner supplied to the latent image in a diagonal swath on the photoreceptor defined by the process surface speed and the channel speed using the received image data. The replenishment amount of toner is added to the depleted developer in the return channel to replenish the developer.

A voltage application unit is caused to start applying a voltage to the charging members upon startup of an image forming apparatus, and a measurement value of an electric current flowing through each charging member is determined by a measurement unit. A charging member of which the measurement value is such that an absolute value of a difference between the reference value and the measurement value is not smaller than a predetermined value is marked by a determination unit. If there is at least one marked charging member and at least one not-marked charging member, a notification produced by a messaging unit is given through a notification unit.

The cleaning unit cleans the surface of the image carrying body after transfer of the toner image onto an image transfer object. The post-transfer neutralization unit is disposed between the transfer unit and the cleaning unit, and neutralizes electrical charge of the surface of the image carrying body after transfer. The first control unit controls neutralization light intensity of the pre-transfer neutralization unit such that a dark potential (V 0 potential) of a non-image region on the image carrying body after pre-transfer neutralization is higher by 50 to 150 V than a bright potential (V L potential) of a solid image region. The first setting operating unit allows for an increase and decrease in the neutralization light intensity of the pre-transfer neutralization unit based on a status of an output image.

The print performance of an image forming apparatus is improved by adequately estimating the behavior of a sheet receiving separation air and controlling the output of separation air. A fixing control unit controls a shutter drive unit defining the flow passage area on the basis of the displacement detected of the separation claw to control the output of separation air. Since the sheet receiving separation air exerts a force on the separation claw it is possible to estimate whether or not the behavior of the sheet is appropriate by monitoring the displacement of the separation claw While different types of paper may move in different ways, the influence of separation air is dominant in the behavior of a sheet which is conveyed, and therefore the sheet can be prevented from moving in an inappropriate condition by controlling the output of separation air. 1.

Density unevenness is suppressed even in an image that is formed by a multiple exposures method in which the same region on a photoreceptor is exposed multiple times with different laser light sources (light emitting elements), by adjusting the amounts of light of the respective lasers based on a density difference among test images. An image is formed for each group of light emitting elements grouped together for multiple exposures by dividing, in the main scanning direction, the region of a test image formed on a recording medium. The images formed for the respective multiple-exposure light emitting element groups are compared to one another in density, to thereby adjust the amounts of light of the respective laser light sources (light emitting elements) and reduce fluctuations in image density. 1.

IMAGE FORMING APPARATUS THAT ENABLES REDUCING TIME REQUIRED FOR ADJUSTMENT OPERATION

Номер: US20130294793A1
Автор: Saida Tadaaki
Принадлежит:

An image forming apparatus is disclosed that can reduce the time required for adjustment operations when a first adjustment operation that requires speed change and a second adjustment operation that does not require speed change overlap. When first adjustment operation that can be performed at a first speed is to be performed during operation at a second speed lower than the first speed, the image formation speed is changed from the second speed to the first speed. When second adjustment operation that can be performed at a plurality of image formation speeds is to be performed during operation at the second speed, the second adjustment operation is performed while maintaining the second speed. When both the first and second adjustment operations are to be performed during operation at the second speed, the image formation speed is changed from the second speed to the first speed.

Apparatus and Method for Destroying an Encoder Wheel

Номер: US20130302043A1
Автор: Christopher E. Nichols, David Dale Bascome, Jr., David G. Thompson, Donald R. Huck
Принадлежит: Static Control Components Inc

Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes an encoder wheel assembly in addition to or instead of a chip for determining toner load. It may be desirable to alter the encoder wheel or part of the cartridge, either by the printer or the cartridge, to permit a deliberate end of life function situation that requires the replacement of the cartridge, encoder wheel, or encoder wheel assembly components. This thereby controls the remanufacture or replacement of the toner cartridge in a way that is desirable to the manufacturer and prevents unauthorized refilling of the cartridge.
