Abstract: In an image formation apparatus, the control temperature of a heat fixing device includes an operation temperature and a standby temperature that is relatively lower than the operation temperature. When an instruction is designated to start an image formation operation, data associated with the start timing of the first image formation operation is calculated. Control of raising the temperature of a roller for heat fixing from the standby temperature to the operation temperature is initiated so that the heat fixing roller attains the operation temperature at the start timing of an image formation operation. As a result, the time of initiating control to raise the temperature to the operation temperature level is optimized to reduce power consumption without increasing the standby time for an image formation operation.

Abstract: A print media sheet tray control system for use with a printing system having a controller is provided. The control system includes a print media sheet tray which is configurable, through use of the controller, in a selected one of a first operational mode and a second operational mode. The configurable print media sheet tray is characterized by a print media attribute set having a selected state which can be either a first state or a second state. If the configurable print media sheet tray is configured in the first operational mode, then the controller prohibits printing system operation if the selected state has been altered from the first state to the second state. On the other hand, if the configurable print media sheet tray is configured in the second operational mode, then operation of the printing system is permitted provided the alteration was achieved pursuant to a preselected alteration process.

Abstract: An image forming apparatus has a backup memory for storing data on image forming in a memory. When the power supply of the apparatus is turned off due to a trouble, a controller reproduces a status just before the power supply is turned off according to the data stored in the backup device if a predetermined time passes after the power supply is turned on again. However, new image forming is started if a preparation operation for new image forming is detected within the predetermined time. Further, if the power supply is turned off while a document is read, the controller reproduces the status just before the power supply is turned off when the power supply is turned on again.

Abstract: An image forming apparatus which forms identical images both on a sheet of a first type (overhead projector sheet) and on a sheet of a second type (normal paper sheet). One-side image formation is performed to form images on front sides of OHP sheets which are then discharged into a non-sort bin. Two-side image formation is performed to form images on the both sides of normal paper sheets which are then sorted and discharged into sort bins. Thus, sets of document sheets for presentation can be prepared in a sorted state. Since images are formed on both sides of the normal paper sheets, the normal sheets can be economized and saved.

The method includes providing a discrete number of parameter settings and printing test patterns based upon the parameter settings. The test patterns are scanned to produce a set of image quality values.

Optimum parameter settings for the printing machine are then determined from the discrete number of parameter settings to produce consistent image quality.

Abstract: Time data required for an exposing lamp to reach to a standby temperature value from the starting of the exposing lamp heater with a rated current, and time data required for a heat roller to reach to the standby temperature from the starting of the heater lamp of the fixing apparatus with a rated current are retained in a ROM. The temperature of the heat roller and of the exposing lamp is detected when the power-save mode releasing has been instructed by the key. The start beginning timing of the exposing lamp heater and of the heater lamp is controlled so that the temperature of the exposing lamp and of the heat roller may become a standby state at substantially the same time from the time data retained based on the detected temperature value.

Abstract: In an image processing apparatus, determination is made whether an interruptive print wait state is attained during interruptive printing. When determination is made that the apparatus is in an interruptive print wait state, an interruption recover process is effected. Then, the apparatus returns to the normal mode prior to interruption. Thus, an image processing apparatus is provided that can have the waiting time caused by an interruption in the normal job reduced.

Abstract: A system for registration of color separation images on a photoconductor belt in an imaging system operates to detect a position of an edge of the photoconductor belt. The registration system detects the position with the same laser scanner used for forming latent images on the photoconductor belt.

Abstract: An image forming apparatus for performing a one-side image formation to form an image of a designated page on a recording sheet is disclosed. Selected from a plurality of pages each carrying an image to be formed, a page can be designated by an operation section. Image formation on one side of a recording sheet carrying an image of the designated page formed on the other side thereof is prohibited. Thus, the recording sheet carries the image of the designated page formed only on one side thereof. Where images on two-sided document original sheets are copied to prepare a set of document copies, for example, one-side image formation is performed to copy an image on a cover sheet or on an inter-sheet for chaptering, while two-side image formation is performed to copy images of the other pages on normal sheets.
