摘要： A method and apparatus of reproducing and recording data stored in a plurality of tracks of a memory. A recording and reproducing head reproduces data from at least one of a plurality of tracks of a disk-shaped recording medium. The reproduced data is stored in a memory and rewritten. Data is read out of the memory and controllably supplied to a recording operation of the recording and reproducing head so that data of every track read out from the memory is recorded on the disk-shaped recording medium. In a preferred embodiment, the reproduced data is stored, rewritten read out from the memory in response to an index signal representing a starting portion of a track and then recorded on a magnetic floppy disk.

摘要： An image It is formed as a patch image which includes a header image portion Ih of a solid image having a length of a circumferential length of a developing roller or more, and a gradation image portion Ig progressively varied in the tone level thereof from the maximum level to the minimum level. The densities of the patch image on an intermediate transfer belt are sampled. However, the sampling results contain errors resulting from noises or variations and hence, are subjected to a noise removal process, a periodical variation correction process and a reverse correction process. The results detected on the intermediate transfer belt do not always coincide with image densities (OD values) on a recording material. Therefore, the detection results are converted into the OD values, based on which tone characteristics of an apparatus is estimated. Then a tone correction table is updated in a manner to compensate for the tone characteristics. This approach is taken to improve image quality on the recording material.

摘要： The present invention provides a printing device whereby a recording agent cartridge that pertains to recording agent cartridge-related information can easily be identified. The printing device of the present invention stores cartridge identification information including user information on each user allocated to one of the multiple recording agent cartridges. When a print job with user identification information is received via the network (S10), the printing device identifies a recording agent cartridge corresponding to a user of the print job and sets the identified recording agent cartridge to an active recording agent cartridge for executing the print job (S20), based on the user identification information received with the print job and the user information. The printing device executes the print job and outputs output information with respect to a specified recording agent cartridge selected among the multiple recording agent cartridges, together with a specific piece of the cartridge identification information regarding the specified recording agent cartridge, which is selected out of the cartridge identification information stored in said cartridge identification information storage module (S30).

摘要： An image forming apparatus adapted for a smooth mounting/dismounting of a process unit and for the reduction of wasteful power consumption is provided.Unless a new image signal is applied after completion of an image forming operation, the apparatus starts a clocking operation by an internal timer (Step S101). If the apparatus is left standstill for a predetermined length of time (Step S102), a sleep process (Step S103) is executed to shift the apparatus to a power save mode to consume less power. When an outside cover is opened (Step S105), on the other hand, the apparatus is shifted to a replacement operation mode (Step S106) in which only the rotation of a development rotary is permitted. However, if the apparatus is left with the outside cover opened (Step S108), the sleep process is executed.

摘要： An electrostatic latent image associated with image data is formed on an image carrier. A developer includes a container containing toner a roller facing the image carrier and causing the toner to adhere onto the image carrier to develop the electrostatic image with the toner as a image, and an applier applying the toner to the roller. A controller is operable to receive the image data and to control the roller in correspondence to the image data. The image data includes first image data corresponding to a first image and second image data corresponding to a second image. The first image is formed onto a trailing end portion of the medium. The controller receives the second image data after the formation of the first image. After the formation of the first image and before the formation of the second image, the controller causes the roller to rotate without causing the toner to adhere onto the image carrier.

摘要： In a monochromatic print mode, an abutting timing on when a secondary transfer roller abuts on an intermediate transfer belt is different from the timing in a color print mode. Specifically, in the monochromatic print mode, the secondary transfer roller abuts on the intermediate transfer belt prior to the start of an exposure process for the first image. Then, the secondary transfer roller is separated from the intermediate transfer belt at completion of the secondary transfer of the final image. Therefore, the secondary transfer roller has already abutted on the intermediate transfer belt at the start of the irradiation of a light beam for forming the first electrostatic latent image. The exposure process is performed with the secondary transfer roller kept abutting on the intermediate transfer belt.
摘要翻译：在单色打印模式中，当二次转印辊抵接在中间转印带上时的邻接定时与彩色打印模式中的定时不同。具体地说，在单色打印模式中，在第一图像的曝光处理开始之前，二次转印辊与中间转印带抵接。然后，在最终图像的二次转印完成时，二次转印辊与中间转印带分离。因此，在用于形成第一静电潜像的光束的照射开始时，二次转印辊已经抵接在中间转印带上。在二次转印辊保持抵靠在中间转印带上的情况下进行曝光处理。
