摘要:
In a device for storing printings, film sheets or similar recording media driven out or an image forming apparatus, bins are each inclined from a top sheet inlet thereof to a bottom sheet outlet thereof. When all the bins are full, such a condition is reported to users. Users having left sheets in the trays for a long period of time are alerted by a warning message. Sheets become needless for users can be automatically disposed of by commands from user stations. A user passes an I.D. card through a card reader to enter an I.D. number, opening a bin corresponding to the I.D. number, dropping the sheet onto a fence for user access.

A sheet feeder incorporated in an image forming apparatus and allowing the distance between the preceding sheet and the succeeding sheet to be reduced to a minimum necessary one. A pair of control rollers whose transport speed is controllable are located upstream of an image forming section with respect to an intended direction of sheet transport. An image transfer and paper separation unit is located at the image forming section. The transport speed of the control rollers is made higher than an image forming speed for any desired period of time after the leading edge of a sheet has been gripped by said control rollers and before the leading edge reaches the image forming section. As a result the distance between the preceding and succeeding sheets is reduced to increase the number of images which can be formed for a unit time without the transport speed at the image forming section being increased.
摘要:
An image forming apparatus, particularly a color image forming apparatus, of the present invention distinguishes a register mark and the background of a conveying member on the basis of the level of a signal representative of the background and the peak value or the bottom value of the signal. The apparatus can therefore accurately detect deviation between images of different colors and correct it.
摘要:
An image forming apparatus includes a plurality of image formation units which print an image of different color on a paper and also form positional deviation detection marks and image density regulation marks, on a conveyer belt or on at least one of a recording medium and an intermediate transfer body that conveys the paper, when such a request is received. When requests for formation of the positional deviation detection marks and the request for the formation of the image density regulation marks is received at the same time or at substantially the same time, the main CPU orchestrates the conveyer belt and the image forming units to form the positional deviation detection marks and the image density regulation marks in continuation.
摘要:
In an image forming apparatus with an ADF (Automatic Document Feeder), a conveyor mechanism sequentially conveys documents from a document feeding section to a document collecting section by way of a slit for scanning the documents. The feeding section and collecting section are disposed one above the other. The ADF including the feeding section and collecting section can be bodily pulled out toward the operator away from a scanner including a CCD (Charge Coupled Device) image sensor, lens, and light source.
摘要:
In an image forming apparatus, an image reading device has a first document setting section for setting a document, and a second document setting section included in an ADF (Automatic Document Feeder) which is capable of supporting and processing a document independently of the first document setting section. The second document setting section allows a number of documents to be stacked thereon. A switching device selectively causes either the document of the first document setting section or that of the second document setting section to be read. A control unit interrupts, when a read request requesting a first reading operation using the first document setting section is input while a second reading operation using the second document setting section is under way, the second reading operation, then executes the first reading operation, and then resumes the second reading operation after the first reading operation.
摘要:
A system includes a device and one or more information processing apparatuses. The device includes a device-information generator configured to generate device information on the device; and an analyzer determining unit configured to determine any one of the device and the one or more information processing apparatuses as an analyzer for the device information. The one determined as the analyzer includes an analysis unit configured to perform an analysis based on the device information; and a service determining unit configured to determine a service to the device based on a result of the analysis.

A rotation measuring mechanism capable of measuring a rotation amount and a displacement amount of a rotary member in a direction perpendicular to the rotation axis is provided. An exemplary combination of the rotation measuring mechanism includes a detection target rotating in synchrony with the rotary member and range sensors. Each time the detection target rotates once, each sensor outputs one cycle of a sine wave. The amplitude of the sine wave output from the sensor varies in accordance with the displacement of the detection target together with the rotary member in the direction perpendicular to the axis, thereby obtaining the rotation amount and the displacement amount of the rotary member.
摘要:
A system abnormality determining method comprises the steps of transmitting fake abnormal information representing an abnormal condition of the target instrument from the target instrument to a condition determination device via a network during a test operation of the target instrument instead of condition information, determining if the condition determination device can determine the target instrument as being abnormal based on the fake abnormal information, and operating the target instrument in a normal operation condition when the condition determination device can determine the target instrument as being abnormal.
