Abstract: An image forming apparatus includes: an operation acceptor; a transporter transporting paper along a transport path; an image former forming an image on the paper on the basis of image data; a paper detector detecting a transport status of the paper on the basis of detection results of paper detection sensors provided at various locations on the transport path; a display; a storage storing a predetermined image showing an assumed jam status of the paper and predetermined guidance for clearing the jam status of the paper when a jam occurs while the paper is transported; and a controller. When the jam occurs while the paper is transported, the controller displays, in a user-selectable manner, a predetermined image showing the paper jam status according to the detection result of the paper detector. When the operation acceptor accepts a selection operation, the controller displays the guidance for clearing the paper jam status.

Abstract: An input device is connected to a display device and an image forming apparatus having an energy saving function. When a prescribed operation instruction suggesting that edition of an image will end soon is received before receiving a print instruction, the input device issues an activation signal causing recovery from an energy saving state to a ready state to the image forming apparatus. Receiving the activation signal, image forming apparatus starts warming-up.

Abstract: In an image forming apparatus, guidance information is stored in advance for guiding an optimal operation procedure for execution of a job, and the guidance information is displayed on a display portion based on operation input that is input to an input portion in order to execute a job of image formation. For example, a device control portion compares operation input that is input to the input portion in order to execute the job of image formation to the guidance information corresponding to the job executed by the operation input, and causes the display portion to display the guidance information in a case where an actual frequency of operation input is greater than a frequency of operation input that is specified in an operation procedure of the guidance information.

Abstract: An image forming apparatus is provided with an image forming portion for forming an image, a nongenuine product judging portion for judging whether or not a toner cartridge as a replacement part of the image forming portion is a nongenuine product and a control portion for controlling the image forming portion according to an image forming condition input from a copy condition input screen or a print condition input screen. In a case where the toner cartridge of the image forming portion is judged as a nongenuine product by the nongenuine product judging portion, the control portion restricts input of a condition concerning recording paper among the image forming conditions capable of being input from the copy condition input screen or the print condition input screen.

The image forming apparatus includes an image forming portion for forming an image, and a nongenuine product judging portion for judging whether or not a toner cartridge as a replacement part of the image forming portion is a nongenuine product. A printer driver of an information processing apparatus prohibits, when the toner cartridge of the image forming portion is judged as a nongenuine product, addition to recording paper a watermark, copy prohibition information or trace information that is purposely added as the specific image information on a print condition input screen with recognition of an important document by a user.
