摘要： PURPOSE:To prevent the malfunctions of an information processor while a recording part is functioning and also to prevent the transfer defects of a recording medium by stopping the function of a 1st input part which serves as a transfer path of the recording medium in a recording mode and using a 2nd input part prepared out of the transfer path for input of documents. CONSTITUTION:When 'document editing' is selected on a main menu by a cursor key, a document editing screen is shown on a display 2. Then a document is inputted by means of various keys of a keyboard 1. Then a print key prepared at a 1st input part 1A of the keyboard 1 is selected and a print mode screen is shown. The set and changeable items are shown on the print mode screen so that the set items are selected and the contents of these items are changed. Furthermore, a necessary function is assigned to a 2nd input part 1B prepared out of a recording paper transfer path when the print mode screen is shown. Thus the function of the part 1A is stopped and therefore no reaction is confirmed even if a key is pushed within a range of the part 1A. In such a constitution, no malfunction of an information processor occurs even if a wrong key is pushed when a recording medium is set.

摘要： PURPOSE:To instantaneously deal with the opposite party of communication by printing the data given from a facsimile equipment after a prescribed quantity of data received from a computer is printed when the data are received from the facsimile equipment while the data received from the computer are printed. CONSTITUTION:If the image data are received from a facsimile equipment 1 while the data received from a personal computer 2 are printed for each line, the image data are converted into the image recording data by an image data converting part 9. Then, the printing mode of the data received from the computer 2 is detected by a printing/recording interface part 8. Thus, these data are printed on a single page of the printing form and this printed form is ejected. Then, the reception of data from the computer 2 is discontinued. Then, the image data received from the equipment 1 are converted into the printer recording data by the part 8 and printed at a printer engine part 12. When the reception of data from the equipment 1 is complete, the data are received again from the computer 2.

摘要： PURPOSE:To prevent the other party of communication from being troubled by interrupting data reception even during print of data from a personal computer to prefer the facsimile communication. CONSTITUTION:If data reception from a facsimile equipment is recognized during reception and print of data from a personal computer 101 with one line as the unit, facsimile picture data reception is reported to a print and recording interface part 107. A busy signal is temporarily sent to the personal computer 101 to stop the data reception from the personal computer 101, and a form on the way of printing is ejected. A form for facsimile recording is sucked instead of it. Thereafter, facsimile picture data is converted to data for recording, and this data is transferred to a picture expanding part 108 and is expanded and is printed by a printer engine part 109. When data reception from the facsimile equipment is terminated, the busy signal to the personal computer 101 is released, and data reception from the personal computer 101 is restarted.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a DMA means is also used for other treatment than processing of data, to increase a DMA bus share and to take time for a DMA transfer process, in an ink jet recorder which uses the DMA means also to read out recording data of a printing buffer having a flag (null flag) set thereto, and converts the read data to null data (zero data) at all times because the recording data of the printing buffer has the flag set without being stored in the printing buffer when the recording data is zero in a predetermined direction. SOLUTION: In the case where the null flag is set, in place of carrying out a process of reading out by the DMA means from the printing buffer, a clearing (zero clear) processing is carried out by a clearing means for a write block for writing the recording data of a data conversion means. A DMA transfer frequency is thus reduced.

摘要： PROBLEM TO BE SOLVED: To solve the trouble of the need for adding a circuit for matching the number of data corresponding to a null flag and the number of data read out from a printing buffer by DMA transfer when these numbers differ because of a specification change brought about to a control circuit by upgrading of a printer or the like. SOLUTION: Information related to the number of data corresponding to the null flag and information related to the number of data read out from the printing buffer by DMA transfer are read out, and both the numbers are compared with each other. In accordance with the comparison result, the number of data corresponding to the null flag is changed to be equal to the number of data read out from the printing buffer by DMA transfer.

摘要： PURPOSE: To perform recording without generating trouble by controlling the feed of a recording medium so as to preliminarily feed the recording medium by the predetermined distance corresponding to the movement of the recording medium generated during the recovery processing of an ink emitting state accompanied by driving in the direction reverse to the moving direction of the recording medium before the recovery processing of the ink emitting state is executed. CONSTITUTION: At the time of recording, the feed motor being the feed drive system of recording paper 5 also drives a recovery system performing recovery processing for keeping and recovering the emitting state of the ink emitted from an ink cartridge 3a. When cleaning operation (recovery processing) is automatically or arbitrarily executed in such a state that the recording paper is set, that is, a PE sensor 3i is turned ON, the position B of a pump gear moves to a position I and, therefore, the recording paper 5 is moved in an A'-direction on the way of cleaning operation. The recording paper 5 is preliminarily fed in a direction A so that the PE sensor 3i is not turned OFF even when the recording paper 5 is moved by A'.

摘要： PURPOSE:To make it possible to prevent contamination and offset caused by ink by providing a means, which can vary the standby time before the start of the back surface recording after the end of the front surface recording of a recording medium in double-surface recording in response to the kind of the recording medium. CONSTITUTION:When the recording for one page is finished, a recording medium 6 is discharged. When the recording operation is made for one-surface recording, the recording medium 6 is discharged on a paper tray 20. For the double-surface recording, the medium is set at a sucking position for back-surface recording. When the recording medium 6 is set at the sucking position for the back-surface recording, the recording is made to wait for the specified time before the start of the back-surface recording. For the standby time, the standby time corresponding to the preset kind of the recording medium 6 is set in the timer of a CPU30. The waiting is performed by driving a timer 35. After the elapse of the preset time of the timer, the recording medium 6 is sucked, the recording data are received from a host computer by the same way as the operation in front-surface recording and the recording is performed for every one line. After the recording of one page is finished, the recording medium 6 is discharged, and the front-surface recording and the back-surface recording are completed.

摘要： PROBLEM TO BE SOLVED: To prevent abnormal rising of a temperature of a motor which may occur when initial signals are continuously transmitted from a host device. SOLUTION: Controlling for providing a waiting time for waiting until an initial operation of the motor, i.e., an initial energizing to a predetermined phase is started after a recorder receives the initial signal from the host device is executed. As the initial energizing is inhibited for a predetermined time period from the reception of the initial signal, it is possible to prevent abnormal rising of the temperature of the motor even when the initial signals are continuously transmitted thereto, thereby improving safety of the recorder.
