Image recording apparatus.

摘要

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.
