A multi-function printer (MFP) has a main control circuit for setting the operation mode of the apparatus to either a normal operation mode or a power-saving operation mode. There are provided a main power supply circuit and an auxiliary power supply circuit for supplying power to the main control circuit in the normal operation mode and in the power-saving operation mode, respectively. The MFP also has a power detection circuit for detecting a state of power supply from the main power supply circuit to the main control circuit. If a power-save request is followed by a start-up request, when an amount of power detected by the power detection circuit is greater than a predetermined value, the main control circuit stops an operation relating to the power-save request and initiates an operation according to a start-up request.

Image forming apparatus

An object of the invention is to provide a display device of an image forming apparatus capable of displaying information that the user wants to obtain in a visually easy-to-recognize manner. In a compound image forming apparatus provided with: one of original reading means for reading image information from an original, image receiving means for receiving image information from a terminal connected to a network and a line image receiving means for receiving image information from a telephone line; image forming means for forming an image based on the image information obtained by the means; and a display portion for displaying the condition of the apparatus, a display condition control portion is provided that changes the display condition of the display portion to a visually easy-to-recognize condition when the condition of the compound image forming apparatus is changed.

A serial recording apparatus in accordance with the present invention appropriately selects ink nozzles of an ink head and prints on a sheet so that the amount of printing is substantially equal to an ordinary amount, when an inadequate amount of sheet feed occurs, and then, selects the ink nozzles of the ink head in accordance with how the inadequate amount of sheet feed is so as to carry out the next printing. This avoids that the inadequate sheet feedings are accumulated in the succeeding printings. Accordingly, even when a plurality of inadequate sheet feedings occur during the printings with respect to a single sheet, the inadequate sheet feedings are not accumulated, thereby avoiding that the quality of the printing deteriorates. Thus, it is possible to provide a serial recording apparatus which can resolve the inadequate printing by detecting the amount of sheet feed for each feeding, determining the print area in accordance with each amount of sheet feed, and carrying out the printing.

Serial recording apparatus

An object of the invention is to provide a display device of an image forming apparatus capable of displaying information that the user wants to obtain in a visually easy-to-recognize manner. In a complex image forming apparatus provided with: one of original reading means for reading image information from an original, image receiving means for receiving image information from a terminal connected to a network and a line image receiving means for receiving image information from a telephone line; image forming means for forming an image based on the image information obtained by the means; and a display portion for displaying the condition of the apparatus, a display condition control portion is provided that changes the display condition of the display portion to a visually easy-to-recognize condition when the condition of the complex image forming apparatus is changed.

An image forming apparatus having a plurality of discharge trays is provided, from which a user can readily obtain printed sheets he has requested. The user inputs a secret code at an operating and displaying section, which secret code the user specified at the terminal device at the time of print request (S ). When a coincidence between the inputted secret code and a secret code stored in secret code storage section is judged (S ), the target discharge tray information corresponding to the secret code is read out from a secret code storage section (memory) and displayed on the operating and displaying section (S ). Accordingly, the user can visually recognize information about a discharge tray on which the user's requested printed sheets are discharged.
