Abstract: A printing system has a printing apparatus and a host apparatus. Print data or control data is transferred between the printing apparatus and the host apparatus in accordance with at least two transfer methods. Upon detecting that a specific state has passed, the printing apparatus or the host apparatus predicts a change of the transfer method when (or immediately after) the specific state has passed. An analysis is conducted to determine whether the transfer method has been changed for the data subsequently transferred. If it is found that the transfer method used in the printing apparatus or the host apparatus has been changed, the other apparatus accordingly changes the transfer method. On the other hand, if the transferred data is based on the currently used method, the method is not changed, but is maintained.

Abstract: A communication apparatus appropriately controls the both-side recording and the both-side reading transmission with respect to a long size source document so as to supply an easily readable reception document to a user on a reception side.

Abstract: When the print sheet number determined based on the mail header is equal to or higher than the predetermined value (“Yes” in S996), the print confirmation screen is displayed in S997 to request the user to indicate whether or not to print the print mail. If the program determines in S998 that the user has indicated his/her desire to print, then the mail is printed in S1030 and S1040. However, if the user has not indicated a desire to print, the print operation is not performed. With this configuration, not all received print mail is immediately targeted for printing. The user can defer printing of print mail having a large amount of data according to circumstances on the receiving end. The large amount of print mail data will not occupy the printer on the receiving end for a long period of time. Hence, urgent or important printing can be given a higher priority.

The divided portion of the input image is output into a corresponding temporary file, and the loading, rotating and outputting steps performed on the divided portions of the input image are repeated until all divided portions of the input image have been processed. The temporary files are then divided into portions, and one divided portion from each temporary file is loaded into the volatile memory.

Abstract: An image output request (representing that image data is stored in a memory) is transmitted from the system on the transmitting side to the system on the receiving side. This image output request includes information such as the name of transmission source and an area where the image data is stored. Upon reception of this image output request, the system on the receiving side notifies the system on the transmitting side of reception of this request. The network is temporarily disconnected. When a predetermined time has elapsed, the system on the receiving side connects the network on the basis of the received image output request and reads out and outputs the image data stored in the memory in the system on the transmitting side. Upon reception of the image data, the system on the receiving side notifies the system on the transmitting side of reception of this data.

Abstract: In an apparatus that has a main power supply and a sub-power supply. In a standby state, the main power supply is turned on for an incoming call for facsimile communication, while the main power supply is not turned on for an incoming call for speech communication. Therefore, the unnecessary turning on and off of the main power supply can be prevented. When the DRPD (Distinguish Ringing Pattern Detect) service is provided, a plurality of telephone numbers are assigned to a single communication line, and a plurality of call signals whose pattern differ are employed for receiving calls. When one of these telephone numbers is used for facsimile and another telephone number is used for a telephone, an incoming call can be identified as being either for facsimile or for telephone by distinguishing between the patterns of the call signals. When the pattern of the call signal is for facsimile, the main power supply is turned on to perform data communication.

Abstract: An image processing system, such as a facsimile system, in which a source transmits information to a receiver. The information includes an identification signal which indicates whether image data or an extended program, such as a diagnostic program, is to follow. If image data follows, the receiver processes the data in a normal manner. If the diagnostic program follows, it is stored in a memory for subsequent execution. Since the program doesn't have to be stored in the memory at all times, the memory is used more efficiently. The receiver may request transmission of the diagnostic program in the event of a system failure. The source may transmit a starting time for execution of the diagnostic program.

Abstract: When a communication apparatus determines that a LAN terminal designated by a transmitting facsimile machine has not logged on to the LAN, the communication apparatus sends a transfer result error back to the facsimile machine and sends the facsimile machine an inquiry as to what measures should be taken subsequently. Depending upon the response to the inquiry, either notification of the incoming call from the facsimile machine is transferred to a proxy user who has logged on to the LAN or it is determined, at fixed time intervals, whether the designated terminal or proxy user has logged on. If log-on can be confirmed, notification of the incoming call is transferred to or printed out. If log-on cannot be confirmed, the received data are erased. Refusal of an incoming call can thus be avoided even if the designated communication terminal on the LAN has not logged on.

Abstract: A communication apparatus performs a maintenance operation in a short period of time, without using a communication apparatus which includes a special communication protocol on a maintenance side. In a facsimile machine 24, upon receipt of a DTMF signal on a communication line 1, the DTMF signal is supplied to a modem 8 through a relay 3 and a transformer T1. This is done such that the modem 8 converts the received DTMF signal into a code signal such as 1 to 0, * and # and supplies the code signal to a CPU 16 through a data bus, formed by a gate array 11 and a main gate array 23. The CPU 16 stores the code in a temporary storage RAM 19, digit by digit. In the meantime, when it is determined that the code signal is "96#," from a RAM 17, the CPU 16 reads a functional parameter associated with the number of a soft switch which is temporarily stored in the RAM 19.

Abstract: A facsimile machine is disclosed that can record and print identifying information pertaining to the transmitter and the transmission of a facsimile message. The invention accommodates and allows for identifying information in many languages, accommodating telephone numbers that are exceptionally long as having more than 20 characters. These features are realized by finding the Transmitting Terminal Identification (TTI) in a transmitted message and forming a bit map therefrom. As a result, terminal identification can be communicated and recorded in virtually any language and can contain information up to the scan length instead of being restricted to a smaller number of characters.

Abstract: An image transmission control method for a facsimile apparatus reduces procedures before and after the sending of an image signal to require less time for the transmission of the image signal, thus improving a network utilization efficiency. The transmission side, when receiving a CED signal transmitted from the reception side, sends a particular tone signal to reduce the procedures before and after the sending of an image signal. NSF, NSS, EOP and MCF signals are communicated between the transmission side and the reception side at a high rate. These signals have a shorter preamble. A suitable communication rate is determined based on the results of learning by use of the previous communication rate and an internally provided model. Whether the reduced procedures are used is also determined from transmission conditions.

Abstract: A method and apparatus for facsimile communication uses subaddress messages sent from a sending facsimile terminal to control how a facsimile image transmission is to be handled, e.g., routed and/or translated, by a receiving facsimile terminal. The invention may be employed through the use of an adapter which is designed to work with existing facsimile terminals which are incapable of generating subaddress messages. The invention, when employed with 10-key facsimile machines which cannot generate by the keys thereof proper subaddress delimiting symbols, automatically transforms non-permitted transmission symbols generated by the key to permitted transmission symbols.

Abstract: A facsimile communication managing data including transmission/reception mode, a telephone number of a called or a calling subscriber, etc. is printed out at a predetermined time interval. Each time a facsimile communication is made, the facsimile communication managing data is stored in a memory. A period of time defining a time interval at which the stored managing data are read out is set through a keyboard. An elapse of the period of time is detected and a detection signal is issued. If the detection signal is output during a non-busy state of the facsimile machine, the managing data are read out of the memory immediately after the occurrence of the detection signal and then printed in a printing station of the facsimile machine, whereas if the detection signal is output during a busy state of the facsimile machine, the managing data are read out after the facsimile machine is turned to the non-busy state and printed in the printing station thereof.
