摘要： An image forming apparatus which has an image signal generator for generating an image signal, an image forming unit for forming an image on a recording medium based on the generated image signal, a feeding unit for feeding the medium to the image forming unit, and a controller for outputting different commands to the image forming unit to control the image forming unit. The feeding unit performs spare paper feeding of the medium to a predetermined position before the generator is set in an image signal output enable state and feeds the medium from the predetermined position to the image forming unit after the generator is set in the image signal output enable state. The image forming unit validates a specific command of the different commands when the specific command is received during at least a spare paper feed period from start of spare paper feeding of the recording medium to start of paper feeding from the predetermined position, thereby maximizing the function of the image forming apparatus.

摘要： A communication system includes a main control unit controlling a plurality of units, a transmitter for transmitting information between the main control unit and the plurality of units, and an error detector. The error detector can include a modulator and demodulator for modulating or demodulating the transmitted information on the basis of a predetermined rule. The error detector detects a communication error in the transmitted information in accordance with the predetermined rule. Alternatively, the error detector can include a transmitted data creator/analyzer for creating data based on the transmitted information in a state in which the information contains positive data and negative data of the same bit in one frame and analyzes data when the data is received. This error detector detects a communication error in the transmitted information on the basis of the comparison between the positive and negative data. The error detector can also include a space bit addition separator for creating data based on the transmitted information in a state in which a predetermined space bit is added in one frame and separates the space bit when the data is received. This error detector detects a communication error in the transmitted information on the basis of the timing at which the space bit and other bits appear.
