Therefore, for example, when checking data whose data has changed for each item in the status page, there is a problem that it takes a lot of time to check a large number of outputs.

  In particular, in the status page that outputs the number of prints for each paper type (paper size) and print mode (black and white, color) in the image forming apparatus as data, the numerical values of these numbers are correctly counted according to the actual print output. In order to verify whether or not the output has been performed, the output for each different type and print mode is actually manually set and executed. There was a problem that it had to be verified visually.

  For the purpose of providing a network printing system including a plurality of printers as a prior art, the network printing system having a small amount of communication traffic for collecting information and a simple computer changing operation for collecting job information and the like Each printer constituting the network printing system is set as a device that transmits printer status information (error / status / job report) to a designated computer according to a designated schedule, and for each printer. There is a method for setting the printer status information to be transmitted to the same computer in the network printing system (see Patent Document 1).

  However, this method also improves the efficiency of the evaluation by automatically verifying whether the status page created by the image forming apparatus is the intended one, in particular, the correctness of the count value of the number of printed pages in the status page. It is not possible to save labor.

  The image forming apparatus 101 according to the embodiment of the present invention will be described below.

[Constitution]
FIG. 1 is a functional block diagram of an image forming apparatus 101 according to an embodiment of the present invention.

  The image forming apparatus 101 includes the following functional blocks, communication I / F (interface) 111, data receiving unit 113, print job control unit 115, status page evaluation unit 117, NVRAM 119, disk control unit 121, disk 123, data analysis. Unit 125, drawing data processing unit 127, drawing unit 129, panel 131, status page creation unit 133, memory management unit 135, system control unit 137, device information holding unit 138, evaluation sequence generation unit 139, correct page input unit 140, A correct page generation unit 141, a number counter 142, an output unit 143, a print engine 145, a number value check unit 151, a memory empty value monitoring unit 153, and a printing speed monitoring unit 155.

  The image forming apparatus 101 is connected to an image forming apparatus B102 or a terminal apparatus 201, which are other image forming apparatuses, via a communication I / F 111.

  The image forming apparatus 101 has a computer (not shown), and each computer implements each functional block (or a control portion of the apparatus indicating each functional block).

  Specifically, a computer is a device that executes a program to perform computation and / or control. The computer has a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). The CPU, ROM, RAM, and interface are connected to each other via a bus, a controller, and the like so that data communication can be performed.

  The CPU is an arithmetic processing unit that executes processing described in a program and forms each functional block inside. The ROM is a non-volatile memory that stores programs and data in advance. The RAM is a memory that temporarily stores the program and data when the program is executed and uses it as a work area.

  Each functional block will be described below.

  A communication I / F (interface) 111 is an intermediary device for connecting the image forming apparatus 101 to a terminal device 201 such as a PC (Personal Computer) or another image forming apparatus (image forming apparatus B102). The communication I / F 111 may be a network interface, or other USB interface or parallel interface.

  The data receiving unit 113 is a functional unit that buffers the print data received by the communication I / F 111 and reconstructs the data for each print data.

  The print job control unit 115 is a functional unit that controls the execution, stop, and completion operations of the print job of the image forming apparatus 101.

  The status page evaluation unit 117 is a functional unit that evaluates a status page generated by the image forming apparatus 101. The image forming apparatus 101 compares and evaluates the bitmap data of the intended correct status page received by the correct page input unit 140 and the bitmap data of the status page output by the status page creation unit 133 of the image forming apparatus 101. Evaluate the validity of the status page to be output. At the time of evaluation, a portion that does not make sense even when compared, such as the execution date and time, firmware version number, etc., may be designated as an ignoring area and the portion may not be compared. Further, it may be determined whether the numerical value in the designated area is within a predetermined range (or whether the character string is in the designated character string). More detailed items of the evaluation function will be described later in the description item of the script of the evaluation sequence.

  An NVRAM (Non Volatile Random Access Memory) 119 is a non-volatile memory and has a function of recording setting information of the image forming apparatus 101. The information stored in the NVRAM 119 does not disappear even when the power is turned off, and the setting state of the image forming apparatus can be maintained regardless of the power state. The setting information stored in the NVRAM is passed to the status page creation unit 133 via the system control unit 137 and output to the status page.

  The disk control unit 121 controls reading and writing of information with respect to a disk 123 formed of a rotating magnetic disk device that is a secondary storage device of the image forming apparatus 101.

  The disk 123 is a secondary storage device of an image forming apparatus composed of a rotating magnetic disk device or the like. A program necessary for the operation of the image forming apparatus 101, image data, and the like are recorded and held, and read out when necessary and appropriately processed such as printout.

  The data analysis unit 125 analyzes a page description language (PDL) and PCL (Printer Control Language) included in the print data, and performs a drawing data processing unit 127, a drawing unit 129, and an output unit described later. Instructions for necessary operations are given to 143 and the like.

  The drawing data processing unit 127 converts print data described in the page description language into a display list that is an intermediate language based on the data analysis of the data analysis unit 125.

  The drawing unit 129 converts the print data written in the intermediate language (display list) converted by the drawing data processing unit 127 into bitmap data to be printed by the print engine 145 via the output unit 143.

  The panel 131 is an interface device for performing input / output with a user, which includes a display unit such as a liquid crystal panel and an input unit such as a touch panel and buttons.

  The status page creation unit 133 is a functional unit that creates a status page for outputting the setting state (or setting value) of the image forming apparatus 101 to a sheet. As described above, various types of information are output to the status page, and information on these setting states is acquired via the system control unit 137. An example of the status page output by the status page creation unit 133 is shown in FIG. The status page shows the model name of the image forming apparatus, the firmware version number, and the number of prints for each sheet and each print type held by the device information holding unit 138. There are other various items such as language setting and local time, but a part of them is shown here as an example.

  The memory management unit 135 is a functional unit that manages a main memory that is a primary storage device of the image forming apparatus 101.

  The system control unit 137 is a functional unit that controls the entire apparatus of the image forming apparatus 101. Information on the setting state of the image forming apparatus 101 is acquired from the device information holding unit 138 and each function unit of the image forming apparatus. The acquired information is passed to the status page creation unit 133 and output as a status page.

  The device information holding unit 138 is a functional unit that holds information about devices such as the number of printed sheets and an effective cassette (a paper feeding cassette that is mounted on the image forming apparatus and is operable). Information held by the device information holding unit 138 is passed to the status page creation unit 133 via the system control unit 137, and the information is output to the status page.

  The device information holding unit 138 has a number counter 142.

Number counter 142 is a functional part for holding by counting the type and size as the print number of sheets of paper housed in each paper feed cassette. When outputting the number of printed sheets counted for each paper type and size on the status page, the status page creation unit 133 acquires the information from the number counter 142 and outputs the information.

  The evaluation sequence generation unit 139 is a functional unit that generates a series of sequences for evaluating the status page. The evaluation sequence controls the image forming apparatus to change the setting state of the image forming apparatus 101 and output the status page by a simple script.

  The script is executed in the following format, for example.

"Command, setting item, setting value"
For example, the size of the paper cassette 1 is set to A4, the paper cassette 2 is set to A3, the respective print sheet counter values are reset to zero, the paper is supplied from the paper cassette 1 and black and white sample pages A script that outputs 5 sheets of paper, supplies paper from the paper feed cassette 2 and outputs 10 black and white sample pages is as follows.

; command execution
START SCRIPT
SET_CAS1_SIZE A4
SET_CAS2_SIZE A3
SET_CAS1_CNT_VALUE 0
SET_CAS2_CNT_VALUE 0
PRINT_FEED_CAS1 MONOCHROME_SAMPLE 5
PRINT_FEED_CAS2 MONOCHROME_SAMPLE 10
After the script, the following status page output and status page evaluation commands are executed.

  The following script performs the following tasks: The mode of the status page is set to the print number counter (see the status page example shown in FIG. 4). Next, the status page is output. If the value of the A4 monochrome counter in the status page is not 5, an error message is issued. If the value of the A3 black and white counter in the status page is not 10, an error message is issued.

; *** evaluation execution ***
SET_STATUS_PAGE_MODE PRINT_COUNTER
PRINT_STATUS_PAGE
IF (MONOCHROME_A4_MONO_CNT_VALUE! = 5) MESSEAGE "A4 MONOCHROME COUNTER VALUE IS WRONG"
IF (MONOCHROME_A3_MONO_CNT_VALUE! = 10) MESSEAGE "A4 MONOCHROME COUNTER VALUE IS WRONG"
END SCRIPT
In the comparison of the counter value in the above script, since the place where the counter numerical value appears is known in advance, the bitmap pattern of the corresponding part is compared with the numerical value. In the above script, only the counter value portion is shown, but other items may be similarly compared. In that case, correct bitmap patterns may be created for all comparison items in advance, and evaluation may be performed based on whether the bitmap patterns match.

  The evaluation sequence generation unit 139 converts the script into PCL (Printer Control Language) and controls the image forming apparatus through the print job control unit 115 and the system control unit 137.

  In the above script, the comparison for only the corresponding number counter has been described, but it is of course possible to use a method for comparing other output portions. For example, a method of creating and evaluating a correct bitmap page for the entire page may be used. In this case, the status page includes items such as status page creation date and time, firmware version number, and the like that have different meanings for comparison with the correct page because the output results differ for each printing or test. In this case, a method may be adopted in which this item (region on the bitmap) is not evaluated (bitmap pattern matching) in advance.

  In that case, for example, the following ignore area setting command is added to the script described above.

SET_IGNORE_REGION 710, 750, 1140, 820; (command, ignore region coordinates)
A method may be adopted in which the ignore area setting command is added during generation of the correct answer page and the correct answer page itself has an ignore area. Further, instead of generating a correct answer page, a method may be used in which the ignore area setting command is added at the time of evaluation and the area is ignored at the time of evaluation.

  FIG. 4 shows an example of a status page and the firmware version number in the page is surrounded by a dotted line to indicate that the area is the ignore area (IGNORE_REGION).

  Further, instead of setting an ignoring area as described above, a method of determining whether a numerical value (or character string) in a specified area is within a specified range (within a plurality of specified character strings) may be used. . For example, when the temperature in the apparatus is output in the status page, it is determined to be normal if it is not a specific value but a predetermined range, so that a value having such a range can be checked.

  For example, check the numeric range with the following command:

VALUE_CHECK_REGION 710, 750, 1140, 820, VALUE <= 500 AND VALUE => 1
The above command is a command for checking whether the numerical value in the XY coordinates (710, 750, 1140, 820) is 1 or more and 500 or less.

  Also, for example, the following command is used to check for the presence of a character string.

STRING_CHECK_REGION 710, 750, 1140, 820, STR ("AAA", "AAB", "AAC")
The above command is a command for checking whether the character string in the XY coordinates (710, 750, 1140, 820) is any one of “AAA”, “AAB”, and “AAC”.

  If the numerical value range and the character string comparison do not match, a method may be used in which the area is painted black, and if the area matches, the bitmap data indicating that the area is not painted is output.

  The correct page input unit 140 receives an input of a status page (hereinafter referred to as a correct page) on which the correct setting state (or setting value) for each item is described according to the setting state of the image forming apparatus 101. The correct page is created, for example, by the status page creation unit 133b of the image forming apparatus B102 (FIG. 1), which is another image forming apparatus for which the validity of the status page has already been verified. The method of accepting via may be sufficient. Further, it may be a correct page created on the terminal device 201 by a document creation program or the like. Furthermore, the correct page which the correct page generation part 141 mentioned later produces | generates may be sufficient. This correct answer page uses not only the correct setting state (or setting value) for each setting item but also the correct output format (setting item name and setting value output position). It is also possible to compare the status page formats output by the creation unit 133.

  The correct page generation unit 141 is a functional unit that generates a correct output (correct page) of the status page generated based on the sequence (described above) generated by the evaluation sequence generation unit 139.

  The output unit 143 receives the print data bitmapped by the drawing unit 129, transmits the print data to the print engine 145 that is a mechanism unit that actually performs printing, and controls data transmission to the print engine 145.

  The print engine 145 is a mechanism unit that prints on paper.

The sheet number check unit 151 accesses the output unit 143, counts the print data printed out by the output unit 143 for each paper type (size) and mode (monochrome, color), and actually prints out the print data. The number of printed sheets is counted. The memory empty value monitoring unit 153 accesses the memory management unit 135 to check whether the count value is correct by comparing the count value with the count value of the number of printed output on the status page created by the status page creation unit 133. Each time a page is created, the free space in the memory is once reserved and reduced for creating the status page, and after the status page is created, the memory is released and the free space is restored. In the process of status page creation executed by the status page creation unit 133, if the memory once secured is not properly released, the memory free space is reduced while a memory leak occurs. The memory empty value monitoring unit 153 monitors whether there is a memory leak in the status page creation process by monitoring the free space of the memory. When the occurrence of a memory leak is monitored, it is displayed on the panel 131 or output to paper by the print engine 145 to notify the user.

The print speed monitoring unit 155 verifies whether a problem (decrease in print speed) occurs in the print speed when the status page is created. Since the thread or process generated when creating the status page executes unnecessary loop processing, for example, there is a problem that the processing of the CPU is consumed and the printing speed decreases. The print speed monitoring unit 155 measures the print time of the print data in the output unit 143 and compares it with the previous value to determine whether or not the print speed decrease due to these has occurred. Monitor for any. When a decrease in the printing speed is observed, it is displayed on the panel 131 or outputted to paper by the print engine 145 to notify the user.

[flowchart]
The status page evaluation operation of the image forming apparatus according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  S11: The evaluation sequence generation unit 139 generates a sequence for changing the setting state of items displayed on the status page in order to evaluate the status page. For example, based on a script for checking the printed sheet counter as described above, the sequence is created by PCL or the like.

  S13: The correct page generation unit 141 generates a correct status page based on the evaluation sequence. The status page to be generated is generated by PDL (page description language), and then converted from PDL to DL (display list) as an intermediate language, and further converted to BM (bitmap) and stored.

  In this case, it is also possible to create a bitmap pattern of the correct number of sheets using the script for the number of printed sheets, and compare only the printed number portion.

  This PDL → DL → BM conversion may be performed by a conversion unit incorporated in the correct page generation unit 141. Alternatively, the conversion may be performed using the data analysis unit 125, the drawing data processing unit 127, and the drawing unit 129 of the image forming apparatus 101.

  The generation of correct pages in S11 and S13 is illustrated in FIG. In this case, the correct answer page is generated based on the evaluation sequence, and is compressed and stored in the disc.

  S15: The evaluation sequence generation unit 139 sets the image forming apparatus 101 according to the sequence. The image forming apparatus 101 is set through the system control unit 137, the print job control unit 115, and the like.

  S17: The print job control unit 115 instructs the status page creation unit 133 to create a status page according to the sequence.

  S19: The status page creation unit 133 obtains setting information of the image forming apparatus 101 from the system control unit 137, and creates a status page based on the setting information. The status page creation unit 133 generates a status page in the PDL format.

  S21: The status page described by the generated PDL is converted into DL (display list) which is an intermediate language by the data analysis unit 125 and the drawing data processing unit 127.

  S23: The status page converted to DL in S19 is converted into a bitmap (BM) by the drawing unit 129. The status page converted into the bitmap is stored in the disk 123 via the disk control unit 121.

  The bitmap data is printed out using the output unit 143 and the print engine 145.

  S25: The status page evaluation unit 117 compares the bitmap data of the correct page generated in S13 with the bitmap data generated in S23.

  S27: As a result of the comparison in S25, if the bitmap data does not match, particularly if the counter value data of the number of prints on the status page does not match, the operation proceeds to S31. If the counter value bitmap data of the same number of printed sheets match, the operation proceeds to S29. The comparison of the bitmap data is performed by pattern matching between the bitmap of the status page created by the status page creation unit 133 that is the evaluation object and the correct page (or the bitmap pattern of the correct value).

  S29: Since the comparison result of the status page in S25 coincides, the fact that there is no problem is recorded.

  S31: Since the comparison result of the status page in S25 does not match, the problem part is recorded for the mismatch point.

  S33: The memory empty value monitoring unit 153 accesses the memory management unit 135 to acquire and record the available memory capacity. The printing speed monitoring unit 155 accesses the output unit 143 and records the printing time.

  S35: If there is a record of the previous memory free capacity in the loop in the sequence, the memory empty value monitoring unit 153 determines whether or not a memory leak has occurred due to an increase in the memory free capacity compared to that value. to decide. Further, the printing speed monitoring unit 155 compares the printing time record in S33 with the previous value to determine whether there is a large delay in the printing time speed. If there is a significant difference from the previous value for these, the operation proceeds to S37. If there is no problem, the operation proceeds to S39.

  S37: Recording a decrease in free space in the memory or a decrease in printing speed in which there is a problem.

  S39: If a sequence that has not been evaluated yet remains in the evaluation sequence, the process proceeds to S15, and the evaluation of the status page is repeated in the same manner for the next sequence. If there is no next sequence, the operation ends.

  S41: The problems recorded in S31 and S37 are displayed on the panel 131 in S41 or output to the paper by the print engine 145. You may do both.

  Through the series of operations described above, the validity of the status page of the image forming apparatus, in particular, the evaluation of the counter value of the number of printed sheets on the status page, the evaluation of the memory leak, and the decrease in the printing speed are automatically and continuously performed.

[Effect of Example]
It is possible to automatically evaluate whether the counter value of the number of printed sheets on the status page generated by the image forming apparatus is correct. Compared with the conventional method of checking the status page by visual inspection, this method can save a lot of time and labor, and eliminates oversight.

  Since the evaluation sequence is generated by describing the setting items and setting values in the script, the status page for the setting items of various image forming devices, not only the counter values, but under various conditions Can be automatically checked in a short time.

  Since the evaluation of the status page is performed by pattern matching using bitmapped data, there is no need to output to a conventional sheet, and the sheet is saved.

  Since it is possible to specify an ignored area that is not compared when evaluating with bitmap data, it is misunderstood that the comparison is performed and the data is incorrect for meaningless data such as date and firmware version number. There is no end.

  When evaluating with bitmap data, the numerical value or character string in the area can be compared to determine whether it is within the specified range or the specified character string. Data verification on values that can be determined is possible.

  In the embodiment of the present invention, the comparison between the correct page and the status page created by the image forming apparatus is performed by pattern matching after bitmap conversion. For example, comparative evaluation is performed at the stage of DL or PDL before bitmap conversion. A method or a method of creating a correct page and a status page created by the status page creation unit as text and comparing only the set values regardless of the format or the like may be used. In this case, the format and the like cannot be compared, but the time required for the comparison evaluation is greatly reduced.

  Alternatively, the data to be compared may be output in HTML format or RTF format instead of text, and a text-based comparison including the format may be performed.
