There are provided an image forming apparatus and a method of controlling the same are provided, which are capable of conveying an insert sheet of a proper page in carrying out a recovery process and simplifying the recovery process, and a storage medium storing a program for executing the method. When a printing start instruction is input and an insert mode has been set, an insert sheet is fed. It is determined whether the insert sheet is for a top page of a copy (bundle) or not. When the insert sheet for the top page is detected, a proper printing operation in the insert mode is started. If the insert sheet is not determined to be for the top page, it is judged that the insert sheet has not been correctly set on the inserter tray, and then the insert sheet is discharged to a non-sort tray. Then, insert sheets are discharged to the non-sort tray until the insert sheet for the top page is detected.

Image forming apparatus that provides insert sheet in proper order, method of controlling the same, and storage medium therefor

A sheet handling apparatus is provided, which is comprised of a plurality of inserter trays for stacking thereon insert sheets to be inserted between recording sheets having images formed thereon. Sheet feeding modes for feeding insert sheets include two kinds, i.e. S-stacking mode and F-stacking mode, that can be set by a mode key displayed on a sheet feeding mode setting screen view. In the S-stacking mode, only first-page insert sheets are stacked on a first inserter tray, and only second-page insert sheets and third-page insert sheets are stacked on second and third inserter trays, respectively. In the F-stacking mode, insert sheets are stacked in order of page on an inserter tray. Sheet feeding is suitably controlled by stacking insert sheets on inserter trays in manners corresponding to respective selected stacking modes.

The present invention aims at restoring backup data in a predetermined order and avoiding damage from being given to the system even when the backup data are destroyed. Flags Ferr and Feeprom and a variable i stored in a DRAM are initialized (S to S ). When the variable i is smaller than the number n of EEPROMs (hereinafter referred to as &ldquo;PROM(s)&rdquo;), the ID code of a PROM in question is read and loaded into the DRAM (S to S ). When the variable i equals the number n, the variable i is cleared (S ). Then, a variable j is initialized (S ), and it is determined whether or not each PROM ID stored in the DRAM matches with a mask ROM ID until the variable j becomes greater than the number n of PROMs (S ). If the answer is &ldquo;No&rdquo;, the variable j is incremented (S ), while if &ldquo;Yes,&rdquo; a number corresponding to the variable j then assumed is loaded into the DRAM as the flag Feeprom (S ). Data in the PROM in question is transferred to an area of the DRAM in which is stored the PROM ID matching with the mask ROM ID.

A sheet perforation device for use in an image forming apparatus eliminates inconveniences such as imperfect punching due to too small a sheet size and completion of image formation without notifying the user that the punching could not be performed despite the user's instruction for punching. Punching setup is made and a starting instruction is given through an operating section. Based on the relationship between a selected sheet size and the spacing of holes to be formed by a punching unit, a determination is made as to whether the punching can be correctly performed, and, if it has been determined that the correct punching will fail, a warning message is displayed on the operating section. If the user gives a starting instruction again after recognizing the warning message, image forming operation is started while the punching setup is automatically canceled.

A CPU circuit unit of a copying machine judges based on image data read by a reading unit whether or not the image data represents a color image, and controls according to the judged result whether or not image forming of the image data is to be performed, whereby an operation to be performed by a user when plural originals mixedly including color originals and black/white originals are copied can be simplified.

Image formation apparatus having selection of different image types for image formation

A power-saving controller for an image-forming apparatus activates a power-saving mode when the image-forming apparatus is operated with a power-saving key while standing by, and controls a fixer to have a target temperature selected by a user beforehand, which is lower than a target temperature of the fixer obtained when the image-forming apparatus stands by. After a predetermined period elapses, when the selected temperature is higher than a predetermined temperature, the power-saving controller controls the fixer to have the predetermined temperature.

An original scanning device can set a brake operation starting timing in a scanner backward movement to a predetermined timing, even if a scanning distance of the device is determined at any distance. To do so, a copy machine starts braking the scanning device when a sensor detects that the scanning device backwardly moved to a predetermined position. In this machine, a distance to be scanned by the scanning device is determined based on an original size or a copy magnification, it is judged whether or not a distance between a turn position of the scanning device and the predetermined position according to the determined distance to be scanned is a distance by which the scanning device can reach a predetermined speed in its backward movement, the scanning device is backwardly moved after forwardly moving it to a position according to the determined distance to be scanned in case of affirmative judgment, and the scanning device is backwardly moved after forwardly moving it to a position according to the distance by which the scanning device can reach the predetermined speed in its backward movement in case of negative judgment.

An image forming apparatus has an automatic power-off function for automatically shutting off a power source of the image forming apparatus when it is not operated for a predetermined time. A time until the automatic power-off function operates is made different in an ordinary standby mode and an interruption mode. The interruption mode is caused by an abnormality such as no paper. The time period in the interruption mode is made longer than the time period in the standby mode. The time period in the interruption mode is also made variable depending on the type of detected abnormality. The power-off time periods may be extended when an instruction is inputted via an operator. In addition, in an image forming apparatus having an original feeding device, a image forming mode is stored in memory and all the originals which have not been imaged will be ejected before the power is shut off in the interrupt mode.

An image processing apparatus reads color images, identifies the colors of an read color image, converts the color image into a monochrome image, synthesizes color recognition information on the monochrome image, and prints the resulting synthesized image as a monochrome image. As a result, even if a low-priced printer is employed, it is possible to provide a monochrome image permitting recognition of the colors of the color original, or quick identification of differences among the colors thereof. Moreover, this allows a user to specify a desired graphic pattern to be associated with a given color, and to obtain collation tables independently of the monochrome image, or to print the specified graphic pattern with any variable magnification power.
