20140147155 | IMAGE FORMING APPARATUS - An image forming apparatus includes an input unit, a printing unit, and a storage device. Printing data of each page included in a printing job is input into the input unit. The printing unit selectively prints a page which is printable without changing attributes of the printing data when input in the same apparatus, among the pages included in the printing job. The storage device stores the printing data of a page which is unprintable without changing the attributes of the printing data when input in the same apparatus, among the printing data of the pages included in the printing job as pending job data. | 05-29-2014 |
20150117890 | IMAGE FORMING APPARATUS - An image forming apparatus includes an ejection tray, a printing portion and a display position. The printing portion prints, on a sheet, an image based on image data and ejects the printed sheet to the ejection tray. The display portion displays ejected-sheet information for notifying the orientation of the front and back surfaces of the printed sheet ejected to the ejection tray and the orientation of the printed image on the printed sheet. | 04-30-2015 |
20150193675 | IMAGE FORMING SYSTEM AND IMAGE FORMING APPARATUS - An event detecting unit detects a specific error event or a specific warning event. An event notice transmitting unit transmits an event notice of the detected event to another image forming apparatus. An event notice receiving unit receives an event notice from another image forming apparatus. A status control unit is capable of changing the operation mode among a normal mode and a sleep mode. The status control unit changes the operation mode to the sleep mode or an out-of-service expression mode if the event notice is received in the normal mode. The out-of-service expression mode includes at least one of (a) putting off a light of the display device, (b) stopping a part or all of internal devices that make operation noise sound, and (c) denying reception of an execution request to a part or all of functions. | 07-09-2015 |
