Description

Description: BACKGROUND OF THE INVENTION The present invention determines appropriate image data by determining whether a partner terminal has a multicolor recording function or a single color function at the time of transmission. The present invention relates to a control method for a multicolor facsimile apparatus which detects whether or not the terminal itself is capable of multicolor recording at the time of transmission and reception, and records on a recording sheet based on the detection result. 2. Description of the Related Art Conventionally, there have been proposed printers capable of multicolor printing in facsimiles, printers and the like.
In this type of printing apparatus, when transmitting / receiving image information using a facsimile having a multicolor printing function, even if the partner terminal has only a single color printing function, the multicolor image information may be transmitted. The partner terminal can only print in single color. Further, the receiving side terminal has a multicolor printing function, and even when multicolor image information is transmitted from the partner terminal, the multicolor printing function is available if there is no multicolor printing paper. However, multicolor printing is not possible. Therefore, even if the facsimile does not have the multicolor printing function, if the facsimile on the transmitting side has the multicolor printing function, transmission is performed in the multicolor printing mode for multicolor printing, and the facsimile on the receiving side. Although it has a multi-color printing function, even in a state in which multi-color printing cannot be performed, signal processing is performed based on the print data transmitted in the multi-color printing mode to print in a single color. Therefore, the signal processing is wasteful and the time until the completion of printing is inevitably increased accordingly. Further, as an example of this type of apparatus, Japanese Patent Laid-Open No.
There is a color facsimile apparatus disclosed in Japanese Unexamined Patent Publication No. 0-80371. This facsimile apparatus is configured to determine whether or not it has a color receiving function, and send out a color image or a monochrome image based on the determination result. Therefore, if the transmitting terminal has a color function, the color image information is forcibly sent out even when color recording cannot be performed, for example, when there is no recording paper for color recording. This causes a problem that image information is not recorded on the receiving side until color recording can be performed. [0007] The present invention has been made in view of the actual situation of the prior art as described above, and its purpose is to:
It is an object of the present invention to provide a control method for a multicolor facsimile machine which can efficiently perform recording. And for other purposes,
When color recording is not possible at the partner terminal, multi-color facsimile that can prevent the image information from becoming unrecorded by appropriately transmitting the image information as monochrome data and causing the receiving side to perform monochrome recording It is to provide a control method of the device. In order to achieve the above object, the present invention provides a receiving means, a transmitting means, a recording means, and
A control method of a multi-color facsimile apparatus, comprising: a supply unit for supplying a recording sheet to a recording unit, and recording the received image information on the recording sheet via the recording unit. Based on the information, it is determined whether the partner device is in a multicolor recordable state, and if it is determined that it is in a multicolor recordable state, the multicolor transmission mode is set and multicolor data is set. On the other hand, if it is judged that the multi-color recording is impossible, the single-color transmission mode is set and the single-color data is transmitted. Whether or not it is detected, this detection result is sent as setting information, and then
Recording is performed on a recording sheet based on multicolor data or single color data transmitted from the partner terminal. According to the above means, the partner device is capable of multicolor recording at the time of transmission, in other words, whether the partner device has the multicolor recording function, and whether or not the partner device has the multicolor recording function. If it is judged whether or not color recording is not possible, the multi-color data is transmitted if the partner device is capable of multi-color recording. Send. As a result, when only single-color printing is possible, data transmission is executed as single-color print data that can be sent in a short time without sending multi-color print data, which requires a long transmission time. It is done efficiently based on. Further, when the partner terminal is incapable of multicolor recording, monochromatic data is transmitted, so that the receiving terminal can handle monochromatic data as
Since the single color recording is performed, the image information is not lost even if the original data is multicolor data. Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 showing a facsimile apparatus according to an embodiment of the present invention, the paper feeding device has two rolls and one roll.
The roll is a normal paper and the other roll is a two-color paper, which is configured for use in a printer of a thermal facsimile. In the figure, the multicolor printing paper 1 is made up of small rolls, and has a paper identification device 2 for identifying the kind of paper by marking the spindle (not shown) for identification and detecting the marking. The normal printing paper 3 is composed of a large roll and also has a paper identification device 4 for identifying the kind of paper. Auxiliary rollers 5 are first provided in the feeding direction of the rolls of the print sheets 1 and 3, and transport rollers 6, 6 for the print sheets are provided in front of these auxiliary rollers 5, respectively. , 6 is arranged in front of the printing paper guide plate 7, and a conveyance roller 8 common to both the printing papers 1 and 3 is provided in front of the guide plate 7. Further, in front of the carrying roller 8, the printing section platen 9 and the thermal head 1 are arranged in a vertical relationship.
0 is arranged, and a cutter 11 and a paper discharge roller 12 are arranged behind them. Further, although not shown in the figure, a controller, a power supply, a drive motor, etc. are provided. Regarding the size of the rolls of the printing papers 1 and 3 described above, the printing papers that are frequently used are set by the large rolls.
Therefore, in the embodiment, the black and white printing paper 3 is set on a large roll, and the two-color printing paper 1 is set on a small roll. Of course, if the frequency of printing paper for two colors is high, the set of large and small rolls is the reverse of the above. A description will be given with reference to FIG. 2 in connection with the sheet identifying devices 2 and 4 for the respective print sheets 1 and 3. In the schematic diagram similar to FIG. 1, S1 is a pre-feed sensor for black and white printing paper, S2 is a pre-feed sensor for multicolor printing paper, S3 is a sensor for black and white printing paper, and S is S.
Reference numeral 4 denotes a multicolor printing paper sensor, and S5 denotes a jam detection sensor. In the figure, the same parts as those in FIG. 1 are designated by the same reference numerals. A basic printing sequence will be described with reference to FIG. 2 in which the paper detection sensors S1 to S5 are arranged in respective portions. In the starting state, the printing paper has either black-and-white printing paper or multi-color printing paper before the jam detection sensor S5, and the remaining printing paper is the black-and-white printing paper pre-feed sensor S1 or the multi-color printing paper pre-printing paper. It is in front of the feed sensor S2. When there is black-and-white printing paper in front of the jam detection sensor S5, and when black-and-white printing is to be performed next, the black-and-white printing paper is pulled back onto the thermal head 10 for printing and feeding. After printing is completed, the paper is fed to the cutter position on the cutter 11, and the paper discharge roller 12 is further rotated to discharge the paper. In the case of multiple pages, write the data of the next page while writing to the set position and cut. After ejecting the last page, the print sheet waits in front of the jam detection sensor S5. When the printing paper is replaced, that is, when the black-and-white printing paper waiting before S5 is replaced by the two-color printing paper, the platen 9, the carrying roller 8 and the black-and-white (normal) printing paper-side carrying roller 6 are used. Reverse it and pull the leading edge of the printing paper back to before S1. After that, the two-color printing paper is transported to S5 by rotating the two-color printing paper side transport roller 6, the transport roller 8 and the platen 9, and stands by until printing starts. Next, the control of the printer will be described. The roll paper to be fed is discriminated as normal paper or two-color paper by the paper discriminating devices 2 and 4 provided on the printing papers 1 and 3, respectively. The device outputs to the transmitting side whether normal printing or two-color printing is possible. When two types of paper are set on the sending side, the controller feeds and prints normal paper when it receives normal black and white image information, and when it receives two-color image information, it selects two-color paper. Send and print. When the paper runs out, the sender and the operator are notified whether normal or two-color printing is possible. FIG. 3 shows a flow chart of the above-mentioned control of the printing apparatus when transmitting and receiving by facsimile.
In facsimile transmission / reception, since two-color printing is not defined in the standard protocol, basically two-color readers currently output only black and white data in communication with machines manufactured by other companies. Some machines defined in-house define a few bits in the non-standard protocol of the in-house mode to determine the transmission / reception mode. The mode judgment of the partner machine shown in FIG. 3 will be briefly described. When it is judged that the partner machine is a two-color writing machine, it is judged whether or not there are multicolor papers. Adopts a two-color transmission mode and transmits two-color on all lines or two-color transmission only when there are multi-color bit lines. On the other hand, if there is no multi-colored paper, it is determined whether or not black-and-white paper is present. If yes, only black-and-white printable is displayed.
It then sends the black and white data while requesting a multicolored paper set. If there is no black-and-white paper, a paper-out error is processed and it is determined that SAF is present. Although the printing paper is described as roll paper in the above embodiment, sheet paper may be used depending on the case. Further, in the apparatus according to the present embodiment, when the cost of the paper depends on the sensitivity of the paper, the paper is switched according to the communication speed, and when the speed is slow, the paper with low sensitivity is used. Running costs can be reduced. As described above, at the time of reception, it is detected whether or not the own (reception) terminal is capable of multicolor recording, and the detection result indicates whether the reception terminal is capable of multicolor recording or monochromatic recording. Since it can send the image information data corresponding to the receiving terminal to the other terminal by sending the status of being impossible to the other terminal, if it can only record in single color, it will take a long time to send multicolor recording data. Data transmission is performed as single color record data that can be transmitted in a short time without
It enables efficient printing. When the own (reception) terminal is not capable of multi-color recording, the image information is appropriately sent out as single-color data, and single-color recording is performed on the receiving side, so that the image information can be recorded on the terminal capable of multi-color recording. Can be prevented from being not recorded.
