  By the way, since the page printer performs printing in units of pages, in order to satisfy the catalog performance determined by the product specifications, an image for printing the next page before printing for one page is completed in the printing unit. Data must have been generated.

  If the image data for the next page is not generated in time, the intermittent operation occurs and continuous printing, which is a feature of the page printer, cannot be performed, so that the printer performance cannot be exhibited and the printing performance is deteriorated. .

  Among these page printers, in particular, page printers using continuous paper (hereinafter referred to as continuous paper printers) are often used in large-scale printing such as core business, so printing performance decreases due to intermittent occurrences. An increase in printing time is a big problem.

  In addition, due to the occurrence of this intermittent occurrence, the problem that the consumption of specific parts is accelerated, and the problem that the printing state in the vicinity of the sheet perforation is deteriorated by pausing between pages are brought up.

  For this reason, when it is recognized that such an intermittent has occurred and the printing performance has deteriorated, maintenance staff or the like of the support center (an organization operated by the vendor manufacturer of the printing apparatus provider) or the like has this problem. A printing apparatus having the same environment as that of the printing apparatus is constructed, and reproduction confirmation is performed to identify a cause of deterioration in printing performance.

  However, even when trying to build a printing device with the same environment as the customer's printing device, it may be difficult to do so because it is often necessary to obtain customer data, etc. And it took an enormous amount of time for analysis.

Since the output content can be referred to infer a process that causes a decrease in printing performance, it is possible to easily identify a factor that decreases the printing performance.

  Hereinafter, embodiments of a printing apparatus and a performance verification method according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram showing an example of the overall configuration of a printing system configured by arranging printing apparatuses according to the present invention. In this embodiment, a case where the printing apparatus according to the present invention is applied to the printer 20 is shown.

  The printing system includes a host computer 10 and a printer 20, and the host computer 10 and the printer 20 may be a network such as a LAN (Local Area Network), a WAN (Wide Area Network), or a USB ( Universal Serial Bus) and Centronics etc. are connected so that they can communicate with each other.

  The host computer 10 is a personal computer having a display unit such as a display and an operation unit such as a keyboard and a mouse, and has a function of outputting print data to the printer 20. The print data is composed of information including one or more page data described in a page description language.

  The printer 20 is a continuous paper printer that performs printing using continuous paper, and fulfills a function of performing printing processing based on print data sent from the host computer 10. Here, in addition to the normal operation mode, the printer 20 is provided with a performance verification mode that is a feature of the present invention.

  This performance verification mode is a mode that is activated by maintenance personnel of the support center at the time of failure analysis. When the performance verification mode is activated, verification information (hereinafter simply referred to as verification information) related to print processing in units of pages in each processing step of the print processing is displayed on the operation panel 23. With reference to the display, it is possible to infer a process that causes a decrease in printing performance.

  In this embodiment, the printing process is largely divided into three processes, a PDL editing process process, a drawing process process, and a print output process, and the operation when displaying the number of pages waiting for processing in each process process is shown. An example will be described.

  Here, a part of the functional configuration of the printer 20 will be described. The printer 20 includes a communication unit 21, a printing unit 22, an operation panel 23, and a controller unit 30.

  The communication unit 21 has a function as a communication interface such as a USB board or a LAN board that connects the printer 20 and the host computer 10. The printer 20 receives print data from the host computer 10 via the communication unit 21.

  The printing unit 22 includes a photosensitive drum, a transfer roller, a fixing unit, and the like, and is a printing mechanism that forms an image on a recording medium such as paper based on an instruction from the controller unit 30. The printing unit 22 is configured by an electrophotographic system using laser light, and performs printing in units of pages.

  The operation panel 23 functions as a user interface that connects the user and the printer 20. Specifically, it includes a display unit 23a that functions as a display device such as a liquid crystal display, and an operation unit 23b that functions as an input device such as operation buttons.

  The controller unit 30 performs a function of performing overall control of the printer 20. Specifically, it is composed of a CPU (Central Processing Unit), a program memory, a working memory, and the like, and the CPU controls the entire printer 20 according to a program stored in the program memory.

  Here, a part of the functional configuration of the controller unit 30 will be described. Here, only the constituent elements according to the present invention will be described.

  The controller unit 30 includes a reception processing unit 31, a reception buffer 32, a PDL editing processing unit 33, a drawing command buffer 34, a drawing processing unit 35, an image data buffer 36, a print control processing unit 37, and verification information. An acquisition unit 38 and a display control unit 39 are provided.

  The reception processing unit 31 receives print data from the host computer 10 via the communication unit 21 and stores it in the reception buffer 32. The reception buffer 32 stores one or a plurality of page data constituting the print data.

  The PDL editing processing unit 33 reads the page data stored in the reception buffer 32, analyzes the PDL control code constituting the page data for each code, converts it into a drawing command, and converts this into the drawing command buffer 34. Store.

  The drawing processing unit 35 reads out the drawing command stored in the drawing command buffer 34, develops it into image data based on this drawing command, and stores this in the image data buffer 36.

  The print control processing unit 37 acquires the image data stored in the image data buffer 36 and transmits the image data to the printing unit 22 to cause the printing unit 22 to execute a printing process based on the image data.

  The verification information acquisition unit 38 acquires verification information (in this embodiment, the number of pages waiting for processing in each processing step) during performance verification test processing (processing performed after the performance verification mode is activated). This processing is performed by receiving notification of the number of pages waiting for processing from various processing function units (reception processing unit 31, PDL editing processing unit 33, drawing processing unit 35, print control processing unit 37) during the printing process. Done.

  The display control unit 39 functions to display an operation screen on the display unit 23 a on the operation panel 23. In particular, in the present invention, a performance verification screen (see FIG. 3) is displayed on the operation panel 23 based on verification information from the verification information acquisition unit 38.

  Next, the outline of the performance verification test process will be described with reference to FIGS. Here, an outline of processing in a case where print data composed of page data of 10 pages is processed to perform a performance verification test will be described.

  The reception processing unit 31 receives print data (one or a plurality of page data) and stores it in the reception buffer 32. The page data stored in the reception buffer 32 is sequentially converted into a drawing command by the PDL editing processing unit 33 and stored in the drawing command buffer 34 (PDL editing processing step).

  The page data (drawing command) stored in the drawing command buffer 34 is sequentially developed into image data in the drawing processing unit 35 and stored in the image data buffer 36 (drawing process step).

  Further, the page data (image data) developed into the image data and stored in the image data buffer 36 is sequentially sent to the printing unit 22 in the print control processing unit 37, and the printing process based on the image data is performed. (Printing output process).

  From the above-described processing flow, it can be seen that the page data that is in the editing process waiting state in the PDL editing processing unit 33 is stored in the reception buffer 32. Here, when the number of pages waiting for the editing process greatly exceeds the appropriate value, it is necessary to improve the speed of the editing process in the PDL editing processing unit 33. For example, if the performance of the PDL editing processing unit 33 is not sufficiently exhibited due to a lack of free space in the drawing command buffer 34, the capacity of the drawing command buffer 34 is increased. We can cope by doing it.

  Further, from the processing flow described above, it is understood that the drawing command buffer 34 stores the page data that is waiting for the drawing processing in the drawing processing unit 35. Here, when the number of pages waiting for drawing processing greatly exceeds the appropriate value, it is necessary to improve the drawing processing speed in the drawing processing unit 35. This improvement in drawing processing speed can be dealt with, for example, by adding a drawing mechanism (drawing accelerator).

  Further, it can be understood from the above-described processing flow that the page data in the print processing waiting state in the printing unit 22 is stored in the image data buffer 36. Here, if there is no page data waiting for printing processing, intermittent printing occurs, and the printing performance cannot be fully exhibited. Therefore, a certain amount of page data must be stored in the image data buffer 36. Don't be. In order to cope with this, it is necessary to review and improve the processing in each processing step in the reception processing unit 31, the PDL editing processing unit 33, and the drawing processing unit 35.

  FIG. 3 is a performance verification screen displayed on the operation panel 23 in the state shown in FIG.

  As shown in the figure, on this performance verification screen, the number of pages waiting to be processed in this process is displayed corresponding to each process. Here, for example, the description will focus on “waiting for editing” and “waiting for drawing”. If “waiting for editing”> “waiting for drawing”, PDL editing processing unit 33, “waiting for editing” <“waiting for drawing”. If there is, it can be said that the drawing processing unit 35 is a cause of a decrease in printing performance.

  Further, if both “waiting for editing” and “waiting for drawing” are numerical values (number of pages) such as “0” and “1”, the transmission performance of the print data from the reception processing unit 31 or the host computer 10 will be described. It can be said that there is a high possibility that the printing performance will be reduced.

  Next, the operation of the printer 20 during the performance verification test process will be described with reference to FIGS.

  FIG. 4 shows a sequence chart showing the operation flow of the printer 20 during the performance verification test process.

  When print data is sent from the host computer 10, the printer 20 starts the reception process of the print data in the reception processing unit 31 (step S101). In this reception process, every time the number of received pages increases, the result of adding the number of received pages is transmitted to the verification information acquisition unit 38.

  When the print data reception process is started and the PDL control code is stored in the reception buffer 32, the PDL edit processing unit 33 starts the PDL edit process (step S102). ). In this PDL editing process, each time the conversion of the PDL control code for one page in the reception buffer 32 into the drawing command is completed, the subtraction result of the number of received pages and the addition result of the number of edited pages are used as the verification information acquisition unit 38. Will be sent to.

  When the PDL editing process is started and the drawing command is stored in the drawing command buffer 34, the drawing process is started in the drawing processing unit 35 (step S103). In this drawing process, each time the drawing command for one page in the drawing command buffer 34 is expanded to image data, the result of subtracting the number of edited pages and the result of adding the number of drawn pages are sent to the verification information acquisition unit 38. Will be sent.

  When the drawing process is started and the image data is stored in the image data buffer 36, the print control processing unit 37 starts the print instruction process (step S104). In this print instruction process, every time the image data in the image data buffer 36 is transmitted to the printing unit 22, the subtraction result of the number of drawn pages is transmitted to the verification information acquisition unit 38.

  In this way, in each processing step, the verification information acquisition unit 38 that has received the addition / subtraction results for the number of pages waiting to be processed each time the addition / subtraction results are received, the verification information summarizing the results is displayed in the display control unit 39. The display control unit 39 that has received and displays the verification information (the number of pages waiting for processing in each processing step: see FIG. 3) on the operation panel 23 (step S105).

  FIG. 5 is a flowchart showing the operation of the reception process in step S101.

  This process is started when print data is sent from the host computer 10 (YES in step S201). When this process is started, in the printer 20, the reception processing unit 31 starts the data reception process and stores it in the reception buffer 32 (step S202).

  In this reception process, every time reception of one page is completed (YES in step S203), the number of received pages is added (+1) (step S204), and the addition result of the number of received pages is displayed as a verification information acquisition unit. 38 (step S205). Note that it is possible to determine whether or not the reception of one page has been completed by detecting a page break command or page management information from the received print data.

  FIG. 6 is a flowchart showing the operation of the PDL editing process in step S102.

  This process is started when page data (PDL control code) is stored in the reception buffer 32 (YES in step S301).

  When this processing is started, the PDL editing processing unit 33 reads page data from the reception buffer 32, analyzes the PDL control code constituting this page data for each code, converts it into a drawing command, This is stored in the drawing command buffer 34 (step S302).

  In this editing process, every time the conversion process for one page is completed (YES in step S303), the number of received pages is subtracted (-1) (step S304), and the number of edited pages is added (+1) (step (S305) The result of subtracting the number of received pages and the result of adding the number of edited pages are transmitted to the verification information acquisition unit 38 (step S306). Whether or not the editing process for one page has been completed can be determined by detecting a page break command or page management information from the read PDL control code.

  FIG. 7 is a flowchart showing the drawing processing operation in step S103.

  This process is started when page data (drawing command) is stored in the drawing command buffer 34 (YES in step S401).

  When this processing is started, the drawing processing unit 35 starts reading the drawing command (in units of pages) from the drawing command buffer 34 and develops the image data based on the drawing command. 36 (step S402).

  In this drawing process, every time the development process for one page is completed (YES in step S403), the number of edited pages is subtracted (-1) (step S404), and the number of drawn pages is added (+1) (step In step S405, the result of subtracting the number of edited pages and the result of adding the number of drawn pages are transmitted to the verification information acquisition unit 38 (step S406).

  FIG. 8 is a flowchart showing the operation of the print instruction process in step S104.

  This process is started when page data (image data) is stored in the image data buffer 36 (YES in step S501).

  When this process is started, first, the print control processing unit 37 checks the printing state of the printing unit 22. That is, it is determined whether or not the printing unit 22 is ready to receive image data.

  As a result, when it is determined that the image data cannot be received (NO in step S502), the process waits as it is, but when it is determined that the image data can be received ( In step S502, YES), image data is transmitted to the printing unit 22 (printing instruction) (step S503), and the printing unit 22 is caused to print the image data.

  In addition to the print instruction, the drawing page number is subtracted (-1) (step S504), and the subtraction result of the drawing page number is transmitted to the verification information acquisition unit 38 (step S505).

  As described above, in the present invention, the number of pages waiting for processing in each processing step of the printing process is acquired, and a performance verification screen (see FIG. 3) is displayed on the operation panel 23 based on the acquired verification information. Since it is configured to display, it is possible to infer a process that causes a decrease in print performance with reference to this display, and thus it is possible to easily identify a decrease factor in print performance.

  Next, Example 2 will be described. In the first embodiment, the case where the number of pages waiting to be processed in each processing step is displayed on the operation panel 23 has been described. In the second embodiment, the processing time for each page required for processing in each processing step is described. An embodiment in which is displayed on the operation panel 23 will be described.

  The configuration of the second embodiment is substantially the same as the configuration of FIG. 1 describing the first embodiment, and therefore, the description thereof will be omitted, and only the operation will be described here. In the second embodiment, the case where the printing process is large and divided into three processes, that is, a reception process, a PDL editing process, and a drawing process, will be described as an example.

  Here, the operation of the printer 20 during the performance verification test process according to the second embodiment will be described with reference to FIGS. 9 to 14.

  FIG. 9 shows a sequence chart showing the operation flow of the printer 20 during the performance verification test process.

  When print data is sent from the host computer 10, the printer 20 starts reception processing of the print data at the reception processing unit 31 (step S601). In this reception process, the processing time required for the reception process is measured for each page, and this is sequentially transmitted to the verification information acquisition unit 38.

  When the print data reception process is started and the PDL control code is stored in the reception buffer 32, the PDL edit processing unit 33 starts the PDL edit process (step S602). ). In this PDL editing process, the processing time required for converting the PDL control code for one page in the reception buffer 32 into a drawing command is measured for each page, and this is sequentially transmitted to the verification information acquisition unit 38. .

  When the PDL editing process is started and the drawing command is stored in the drawing command buffer 34, the drawing processing unit 35 starts the drawing process (step S603). In this drawing process, the processing time required to develop the drawing command for one page in the drawing command buffer 34 into image data is measured for each page, and this is sequentially transmitted to the verification information acquisition unit 38.

  In this way, the verification information acquisition unit 38 that has received the processing time required for processing in each processing step (page unit) writes this in the page information structure shown in FIG. 10 for each page (step S604). ).

  Here, when the processing in steps S601 to S604 described above is completed and the measurement of the processing time in each processing step is completed (step S605), the verification information acquisition unit 38 stores the page information structure created in step S604. The display control unit 39 that has passed the display control unit 39 and displays it displays the verification information (processing time required for processing in each processing step: see FIG. 11) on the operation panel 23 (step S606). ).

  FIG. 12 is a flowchart showing the operation of the reception process in step S601.

  This process is started when print data is sent from the host computer 10 (YES in step S701). When this process is started, first, measurement of the processing time required for the reception process is started (step S702).

  Along with the start of processing time measurement, the reception processing unit 31 starts print data reception processing and stores it in the reception buffer (step S703). This reception process is continuously performed until reception of one page is completed (NO in step S704). When reception of one page is completed (YES in step S704), this reception process is performed. Is sent to the verification information acquisition unit 38. Note that it is possible to determine whether or not the reception of one page has been completed by detecting a page break command or page management information from the received print data.

  FIG. 13 is a flowchart showing the operation of the PDL editing process in step S602.

  This process is started when page data (PDL control code) is stored in the reception buffer 32 (YES in step S801). When this process is started, measurement of the processing time required for the editing process is started (step S802).

  As the processing time starts, the PDL editing processing unit 33 reads page data from the reception buffer 32, analyzes the PDL control code constituting the page data for each code, converts it into a drawing command, Is stored in the drawing command buffer 34 (step S803).

  This editing process is continuously performed until the conversion for one page is completed (NO in step S804). When the conversion for one page is completed (YES in step S804), this editing process is performed. Is sent to the verification information acquisition unit 38. Whether or not editing for one page has been completed can be determined by detecting a page break command or page management information from the read PDL control code.

  FIG. 14 is a flowchart showing the drawing processing operation in step S603.

  This process is started when page data (drawing command) is stored in the drawing command buffer 34 (YES in step S901). When this process is started, measurement of the processing time required for the drawing process is started first (step S902).

  Along with the start of measurement of the processing time, the drawing processing unit 35 starts reading the drawing command (in units of pages) from the drawing command buffer 34 and develops it into image data based on this drawing command. The data is stored in the data buffer 36 (step S903).

  This drawing process is continuously performed until the development for one page is completed (NO in step S904). When the development for one page is completed (YES in step S904), the drawing process is performed. The processing time (drawing processing time) required for the process is transmitted to the verification information acquisition unit 38.

  As described above, in the second embodiment, the processing time required for processing in each processing step of the printing process is acquired for each page, and the performance verification screen (see FIG. 11) is displayed on the operation panel based on the acquired verification information. Since the display is displayed on the screen 23, it is possible to infer a process that causes a decrease in print performance with reference to this display, and thus it is possible to easily identify the cause of a decrease in print performance.

  The verification information described with reference to the example in the first embodiment and the second embodiment may be any information as long as it can evaluate the printing performance in each processing step. As an example, the first is the actual speed in the customer data with respect to the printing speed (one page processing time) on the catalog performance, or the ratio relationship between the values of both. In this case, a verification result screen as shown in FIG. 15 is displayed, and the processing steps to be improved can be numerically recognized by the ratio displayed here.

  Secondly, a value obtained by calculating an actual speed in customer data with respect to a printing speed (the number of lines that can be printed per minute) in catalog performance is calculated in terms of LPM (Line Per Minutes). In this case, a verification result screen as shown in FIG. 16 is displayed, and the processing speed in each processing step is displayed in LPM conversion.
