A data processing apparatus includes: a receiving unit configured to receive input data including processing-target data from outside; a measuring unit configured to measure the data amount of the processing-target data included in the received input data; a data processing unit configured to perform predetermined processing on the processing-target data, and to output a result of the processing as output data; and a control unit configured to set the data processing unit to an active state based on reception of the input data by the receiving unit, and when the data amount of the output data reaches the data amount of data obtained by performing the predetermined processing on data of the data amount measured by the measuring unit, to set the data processing unit to a sleep state.

Data processing apparatus

An image forming apparatus has an image forming unit and a feeding unit for feeding a recording material at a predetermined speed to the image forming unit. A reflective type sensor reads irradiated light reflected off of the recording material and an image reading unit reads the light so as to obtain a surface image of the recording material so that a feed control unit can control the feeding of the recording medium so that a moving distance is shorter and in the case of feeding it at a predetermined speed while the recording material is read by the image reading unit. In the image forming apparatus a reflective type determination unit determines a predetermined attribute of the recording material using the surface image of the recording material read by the image reading unit so that the image forming apparatus can determine a kind of recording material based on the attribute obtain so as to form the image on the recording material.

To solve a problem of an increase of kinds of toner patches required for an adjustment accompanying an increase of kinds of half tones to be coped with that results from an intention of acquiring more stable image by forming the toner patches between paper sheets. It becomes possible to form more toner patches and therefore to deal with an increase of kinds of toner patches by correcting a density in a space of a line count obtained by summing up a line count corresponding to a space between paper sheets during a continuous printing operation, a rear-end blank line count of the n-th page, and a leading-end blank line count of the (n+1)th page that is enabled by comparing the size of a recording material and the size of pixel data and thereby by identifying a blank portion of the recording material.

A printer has a controller unit and an engine unit, which are connected via a video interface. Upon reception of a designating command for designating a type of condition, whose condition change is to be reported, from the controller unit, the engine unit supplies a designated condition change signal to the controller unit immediately after the condition of the designated type has changed. The controller unit requests the engine unit to output detailed data associated with the status change in response to reception of the designated condition change signal.

Image forming apparatus and method used therefor

A method and apparatus for forming an image reduce the processing load on a video controller. A CPU causes a counter to start counting the optical beam detection signals of a photodiode in accordance with a signal which indicates the leading edge of a sheet of recording paper received from a TOP sensor. Comparators compare the count value issued from the counter with the values set by the CPU at registers. Based on the comparison result, an F/F sets Q output. Thus, a BD signal is issued through a gate during a period specified by the values set at the registers. The use of the BD signal reduces the processing load on the video controller which generates and transfers an image signal.

A color image formation system in which transfer means for sequentially receiving plural color images is idled if raster image data for a color has not yet been converted from a page description language into the raster image. A page description language or other code data for a first color is converted into a raster image of the first color and an electrophotographic process is commenced whereby a laser beam is modulated in accordance with the raster image of the first color and the image formed by the modulated laser beam is transferred to rotatable transfer means. After image formation in the first color is complete, code data for the second color is converted into raster image data. If conversion of the second color is not yet complete but the transfer means has rotated to a position where it is ready to receive the second color, the transfer means is idled by continued rotation thereof and forcibly restricting laser beam illumination whereby the transfer means is fed blank to a predetermined position. The transfer means is idled until the conversion of second color is complete, whereafter the laser beam is modulated in accordance with the raster image of the second color to form the second color on the transfer means. Processing for third and subsequent colors is continued as above until a full color image has been formed on the transfer means.

In an image printing operation, advance sheet feeding is performed if the size of a recording medium is known upon feeding at least one sheet of the recording medium. To the contrary, advance sheet feeding is not performed if the size of a recording medium is not known, for example, immediately after a power supply has been turned on or after a new supply of recording medium has been placed in a sheet feeding unit.

The present invention has an object to provide an image forming apparatus and method which enables an operator to easily adjust to the desired printing density. A paper feeding roller is driven in timing along with a registration roller. The irradiation of a modulated laser beam is started, a developing high-voltage is changed from '0' V to a predetermined voltage V1, and the voltage is changed to V2 at other timings. By sequentially changing the voltage in this manner, the printing densities from laser modulating data d1 to d10 are adjusted and printing in different densities can be performed.
