    Abstract: An image reading apparatus individually reads a predetermined white reference plate by flickering light sources of the respective colors before an original image is read by sequentially turning on the light sources during one line sync period. The flickering duty ratio of the light source obtained when the white reference plate is read is set for each color so as to maximize the output value from an A/D converter within its predetermined conversion range. When an original is read, the image reading apparatus changes the emission color by switching the light source to be flickered every line sync period, and turns on the light sources of the respective colors in accordance with different duty ratios set for these colors.

    Abstract: An image forming apparatus which has a facsimile function by which it records image data received in facsimile communications and a printer function by which it records image data output from a host computer. The apparatus includes a printing mode setting device for setting the apparatus to one of a plurality of printing modes, a recording device for recording image data, a reception device for receiving facsimile image data, and a control device for causing the setting device to set the apparatus to a specific printing mode when facsimile image data received by the reception device is to be recorded, independent of any printing mode in which the apparatus has previously been set by the setting device. The plurality of printing modes include at least one of a draft mode in which image data is recorded in a thinned-out form and a high-quality mode in which recording is performed by one-direction printing. The specific mode is a two-direction recording mode.

    Abstract: An image recording apparatus includes a FAX unit (1) and a printer unit (2). The printer unit (2) has an ink-jet printing head (205), and records an image in accordance with image data received by the FAX unit (1). In this apparatus, when the power supply is turned on, the printer unit (2) performs a hard power-ON initialization process to initialize a watch-dog timer, registers, the work area of a RAM, and the like, and also initializes the RAM to erase data left in buffers. Thereafter, the printer unit transfers to a standby state. When a print request or a printer setting request is generated in the standby state, a soft power supply initialization process is executed to perform checking of the RAM, initialization of the work area, and initialization of carriage control and paper feed control, and the like. In the standby state, LEDs and the like of the printer unit are kept OFF. An operation error of the printer unit caused by remaining data can be prevented, and reliability of the apparatus can be improved. In addition, unnecessary power consumption can be prevented.
