Then, the remaining length of recording paper is calculated by subtracting the length of used recording paper from the said total length of recording paper and displaying the remaining length of recording paper.
Description
DISPLAYING REMAINING ROLL-PAPER LENGTH
IN IMAGE FORMING APPARATUS
The present invention relates to a method of displaying the remaining length of recording paper in image-forming systems using roll-paper, such as facsimile systems.
In facsimile systems using roll-paper, the remaining length of recording paper should be checked to allow the system to completely receive incoming documents. In a conventional facsimile, the remaining length of the recording paper has to be checked by opening a paper box or looking through a transparent portion at the recording paper. In the above facsimile, a message "No-Paper" is displayed through a displaying window (liquid crystal display (LCD) or light emitting diode (LED)) only in the case where the recording paper is exhausted. However, the problem arises that the receipt of documents cannot be completed due to exhaustion of the recording paper in the middle of the receiving operation.
It is therefore an object of the invention to provide an improved method of displaying the remaining length of recording paper.
Accordingly, the present invention provides a method of displaying the remaining length of recording paper in an image forming apparatus using roll-paper comprising the steps of:
registering the total length of recording paper when the recording paper is supplied to a recording paper receptacle;
counting the length of recording paper used when a document is reproduced;
calculating the remaining length of recording paper by subtracting the length of used recording paper from the said total length of recording paper and displaying the remaining length of recording paper.
The method may further comprise storing the counted length of used recording paper and calculating the remaining length of recording paper by reading the said total length of recording paper and then subtracting the stored length of used printed recording paper from the said total length of recording paper.
The remaining length of recording paper may be displayed on display means when a corresponding display key of the image forming apparatus is activated.
Preferably, the registering step comprises the steps of:
displaying a message requesting the input of the length of recording paper when a register key of the imageforming apparatus is activated; and
receiving and storing the said total length of recording paper after displaying that message.
The registering step may further comprise displaying the said total length of recording paper after receiving and storing it.
Furthermore, the method may comprise the step of activating an alarm when the remaining length of recording paper is less than a preset length.
The present invention also provides image forming apparatus adapted to use roll-paper and comprising:
a keypad for registering a total length of recording paper;
means for counting the length of recording paper used when a document is reproduced;
means for calculating the remaining length of recording paper by subtracting the length of used recording paper from the said total length of recording paper and displaying the remaining length of recording paper.
The apparatus may further comprise a display key, a display and means for displaying the remaining length of recording paper on the display when the display key is activated.
Additionally, the apparatus may further comprise:
a register key;
means for displaying on the display a message requesting the input of the length of recording paper when the register key is activated; and
means for receiving via said keypad and storing the said total length of recording paper.
The apparatus may include an alarm and means for activating the alarm when the remaining length of recording paper is less than a preset length.
The invention is especially applicable to image forming apparatus comprising a facsimile.
The following is a detailed description of a preferred embodiment of the invention with reference to the accompanying drawings, in which like numbers indicate the same or similar elements and:
Fig.l is a block diagram illustrating the construction of a facsimile system according to the present invention;
Fig. 2 is a flow chart illustrating the setting of the length of recording paper, and;
Fig. 3 is a flow chart illustrating the display of the remaining length of recording paper.
Fig.l is a block diagram illustrating the construction of a facsimile system according to the present invention. A central processing unit 10 (hereinafter, referred to as "CPU") counts the length of printed recording paper according to a preset program and prints recorded image data from received information a document to be copied. An operating panel (hereinafter, referred to as "OPE") 20 comprises a key for inputting sheets of the recording paper and a plurality of function keys. Through the OPE 20, key data is input to the CPU 10 and the received key data is displayed under the control of the CPU 10. A memory part 30 stores received image data and the program for displaying the remaining length of the recording paper. Also the memory part 30 accesses and stores data under the control of the CPU 10.
A scanner 40 scans the image of input documents, converts the scanned image data to digital image data, and then inputs the digital image data to the CPU 10. A modem 50 modulates input data in a digital-to-analog manner and then outputs the modulated data to a network control unit 60 (hereinafter, referred to as "NCU") under the control of the CPU 10. The modem 50 demodulates the received analog data to output the demodulated data to the NCU 60. The NCU 60 is operated under the control of the CPU 10 to form a talk loop of a telephone line, and interfaces a signal of the modem 50 with a signal of the telephone line. A printer 70 prints the received video data on the recording paper under the control of the CPU 10. A sensor 80 senses whether or not the recording paper is jammed or transferred, and inputs a signal associated therewith to the CPU 10.
Fig. 2 is a flow chart illustrating setting the length of the recording paper. The flow chart of Fig.2 comprises the steps of supplying the recording paper with a recording paper box, inputting and storing the total length of the recording paper after a register key is operated, and displaying the total length of the registered recording paper associated with the input register key through the displaying unit.
Fig. 3 is a flow chart illustrating displaying the remaining length of the recording paper. The flow chart of
Fig.3 comprises the steps of counting the length of a printed recording paper at the time of printing; storing the length of the printed recording paper; reading the total length of the registered recording paper and then subtracting the length of the printed recording paper from the total length of the registered recording paper, thereby to calculate the remaining length of the recording paper; and displaying the remaining length of the recording paper when a display key is operated.
Referring to Figs.l to 3, one preferred embodiment of the present invention will be described in detail.
A user of the facsimile system supplies the recording paper to the recording paper box in step 21, and at this time since the recording paper is wrapped and supplied in a certain length unit when manufactured, the user can recognize the total length of the recording paper. The CPU 10 checks whether or not the register key of the OPE 20 is operated at step 22. At this time, if the register key is not operated, the program is terminated, and otherwise, step 23 is performed. At step 23, the CPU 10 displays a message requesting the operator to input the length of the recording paper on the display unit of the OPE 20, and step 24 is performed.The user inputs the total length of the recording paper supplied to the recording paper box, by operating number keys provided in the OPE 20, and at this time, the CPU 10 checks whether a key signal corresponding to the total length of the recording paper is input, and if the key signal corresponding to the total length of the recording paper is input, step 25 is performed. At step 25, the CPU 10 stores the total length of the recording paper in the memory part 30 and displays the total length of the recording paper on the display unit of the OPE 20, and then the program is terminated.
The operational step of registering the total length of the recording paper supplied to the recording paper box has been described. The process of displaying the remaining length of recording paper in the recording paper box when printing data on the recording paper associated with received or copied documents will now be described with reference to Fig.3.
At step 31, the CPU 10 checks whether or not a printing operation has begun and if the printing operation has begun, step 32 is performed. At step 32, the CPU 10 checks whether or not the printing operation has begun and a transfer operation of one page worth of paper is sensed by the sensor 80. If the transfer operation of the paper is sensed, the transferred paper is counted by increasing a counter by 1 at step 33. At step 34, the CPU 10 checks whether or not the printing operation is complete, and if the printing operation is not complete, a transfer operation for the next page worth of paper is again sensed at step 32 so that the length of printed recording paper is continuously counted until the printing operation is complete.As in the above, if the printing operation is complete at step 34, at step 35 the CPU 10 stores the length of the recording paper printed, and then step 36 is performed. At step 36, the CPU 10 checks whether or not the total length of the recording paper registered at the time of supplying the recording paper to the recording paper box is stored in the memory part 30, and if it is stored in the memory part 30, step 37 is performed. At step 37, the CPU 10 reads the total length of the recording paper stored in the memory part 30 and then subtracts the length of the printed recording paper from the total length of the recording paper stored in the memory part 30, thereby to calculate the remaining length of the recording paper, and then step 38 is performed.For example, if the total length of the recording paper is registered as 30 meters, the length of the printed recording paper 3 meters is subtracted from the total length of the recording paper 30 meters, as a result the remaining length of the recording paper is 27 meters (30 - 3 = 27). Afterwards, at step 38, the CPU 10 stores the calculated remaining length of the recording paper in the memory part 30, and then step 39 is performed. At step 39, the CPU 10 checks whether or not a display key is operated on the OPE 20, and if the display key is operated step 41 is performed. At step 41, the CPU 10 displays the remaining length of recording paper on the display unit of the OPE 20, thereby making it possible for the user to confirm the remaining length of recording paper.
One embodiment of the present invention has been described in which the remaining length of recording paper is calculated and displayed on the display unit. However, other embodiments can be realised, e.g. in such a way that a message requesting a refill of recording paper is sent to the user by way of, for example, outputting an alarming sound through a speaker 90 when a printing operation is performed by copying or receiving data associated with a document and as a result, the remaining length of the recording paper preset length of recording paper.
As described above, the present invention has an advantage in that the recording paper can be interchanged with new paper before fully exhausted, to thereby preventing the reception of data from being interrupted.
While there have been illustrated and described what are considered to be preferred embodiments of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made, and equivalents may be substituted for elements thereof without departing from the true scope of the present invention.
