  • Image forming apparatus and communication data handling method therein
    Patent number: 7461300
    Abstract: The present invention aims at avoiding a hung-up in the case where a command is sent from a controller within a printer but there is no response to the command from the unit side within the printer, due to a faulty communication or the like, and also in the case where a noise is introduced in the communication data. In the present invention, based on a command sent to the unit side, a data amount of a response from the unit side to this command is predicted, and also a threshold value of response time is provided (S21), which is the time when from the command is sent until the time when the response is received. After the command is sent (S23) until the threshold value of the response time elapses, the receive data is sequentially stored in the receive buffer up to when the data amount from the unit side reaches the predicted data amount (S28, 32, 34).
