摘要:
An image forming apparatus includes a device for setting the apparatus in a check mode to check a state of the apparatus and for selectively executing one of a plurality of check operations. In one aspect, each check operation is set using a commonly provided numeral key, and the check mode is unconditionally released using a clear key. In another aspect, one of the check modes includes a test movement of a movable member used in image formation. In still other aspects, sheet transporting operations are controlled based on the location of a sheet jam, or based on the selection of a sheet sorter. The state of each of the image formation devices is checked even if an improper state has already been detected, plural error states are repeatedly displayed in a specific order, and a display unit is commonly used.

An image forming apparatus includes an image forming mechanism, an input device for setting image formation data necessary to command desired image formation, first and second displays for displaying the data input through the input device and for indicating that the apparatus is ready to form images, respectively, a starter for commanding image formation to commence, a timer, and a controller. The timer controls the first display to return the image formation data to predetermined values if the starter has not been actuated during a predetermined time interval. The controller controls the image forming mechanism to form an image according to the displayed data if the starter is actuated after the ready indication, controls the input device to allow the input of data even before the ready indication in which case the timer begins to time after the ready indication, and controls the timer to reset if new image formation data is input during the predetermined time.
摘要:
An image forming apparatus includes a process input device for setting various data for image formation, process unit for making images on a recording medium repeatedly in accordance with the data set by the input device, detection devices for detecting a trouble of the process unit, a control unit for selectively controlling the detecting operations of the detection devices, and circuitry for preventing the image forming operation in response to the detection of a trouble by the detection devices. In the apparatus, diagnosis is executed for objects to which it is necessary and the image forming process is controlled by the outcome of the diagnosis.
摘要:
An image forming device having a plurality of image forming modes to enable an image reproduced member to be formed under various conditions, in which a predetermined image forming mode is selected out of the abovementioned image forming modes and automatically set when the power source is turned on, or after the image formation has been finished, or in other particular states.
