Abstract

PURPOSE:To know type of an error to be identified from an error code by sequentially storing history data of malfunction generation of one set of total printing number and total operating time from the start of a malfunction factor and operation to generation of the malfunction each time the malfunction is generated during operation. CONSTITUTION:If a sheet clogging or a malfunction in a mechanism or an electronic component in a printer 5 occurs during printing operation, a CPU 1 stores an error code allocated to corresponding malfunction factor, and a page counted value and an hour meter value at the time of malfunction generated in a configuration of an error history data in a memory address 0002H, then moves, if next malfunction occurs, the error history data stored before in next error history data area, and stores the error history data at the time of the malfunction generated in an error history data area 221 from the address 0002H. Accordingly, the respective history data are stored from new history data at the time of a malfunction generated in the data area 221 from the address 0002H to sequentially store the history data generated at the older times in the data area having many memory addresses.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device used as an output device in an information processing system.

[Conventional technology]

Conventionally, in this type of printer device, when guaranteeing the operation of the operating device and checking the usage status based on the history of abnormality occurrences, the device itself does not remember abnormalities that occur during operation.
The operator kept a record of every anomaly that occurred during operation.

[Problem to be solved by the invention]

In the conventional printer device described above, when guaranteeing operational performance and checking the operational status based on the history of abnormality occurrences, the operator records each abnormality occurrence one by one.
Not only is it time-consuming, but it also has the disadvantage that historical data may be missing.

[Means to solve the problem]

The printer device of the present invention edits print data transferred from a host device into a data structure for printing on paper, and develops the print data into bit pattern data based on the control of a CPU. In a printer device that prints on paper, the CPU is configured to count up the time during which the device is in operation at regular intervals.
and an error history memory that stores a history of abnormalities that have occurred in the device, and the error history memory is incremented every time the CPU prints one page from the start of operation to the present. a page counter area for storing the total number of sheets printed up to the present time; and an hour meter area for storing the total operating time from the start of operation of the printer device up to the present time, which is counted up at the fixed time intervals according to instructions from the timer. An error code assigned to the cause of the abnormality each time an abnormality occurs during printing, and page count data read from the page counter area and the hour meter area respectively at the time of the abnormality,
The non-volatile memory is characterized by having a plurality of error history data areas for storing error history data including one set of hour meter data. The apparatus also includes means for printing the contents of the error history memory on the paper.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the printer device of the present invention, FIG. 2 is a diagram showing an example of the structure of data stored in the error history memory in FIG. 1, and FIG. 3 is a block diagram showing an example of the error history memory in FIG. FIG. 6 is a diagram showing a print result of the contents of data stored in a history memory.

As shown in FIG. 1, the printer device of this embodiment has a CPU
A history memory 2 is a non-volatile memory that stores the status when an abnormality occurs during the printing operation under the control of 1 as numerical data, and a history memory 2 is a nonvolatile memory that stores the status when an abnormality occurs as numerical data. A timer 3 that generates a signal for measuring and a count instruction signal every minute for measuring the operation time of the printer device, a panel switch 4 that is pressed by the operator when printing error history contents, and a printer section 5 It is equipped with

The error/history memory 2 is stored in the CPUI as shown in FIG.
Page counter area 20, which stores the total number of printed pages and total operating time measured by 20. It consists of an hour meter area 21 and a plurality of error history data areas 221 to 22n, and each error history data area contains an error code assigned to each abnormality cause and an error code read from the page counter area 20 each time an abnormality occurs. The page count value and the hour meter value read from the hour meter area 21 are stored as one set.

Next, the operation of this embodiment will be explained.

If a paper jam occurs or an abnormality occurs in a mechanical part or electronic component in the print section 5 during printing operation, the CPU 1 outputs the error code assigned to the cause of the abnormality and the page count value and hour meter value at the time of the abnormality occurrence. and the second
Memory address 0O with the configuration of error history data shown in the figure.
When an error occurs next time, the previously stored error history data is moved to the next error history data area, and the error history at the time of occurrence of this error is stored in the error history data area 221 from memory address 0002u. Store data. Therefore, for each error history data, the new history data at the time of abnormality occurrence is at memory address 0002.
The error history data from M is stored in the error history data area 221, and the saw error history data that occurs at an older point in time is stored in the error history data area with a larger number of memory addresses.

Furthermore, when the number of error history data reaches n or more, that is, when the (n+]-)th abnormality occurs after the first abnormality occurs, the data in the error history data area 22n is erased, and the data in the error history data area 221 (n
-1-1,) error history data at the time of occurrence is stored. Therefore, the error history memory 2 always stores error history data corresponding to 00 abnormal occurrences going back from the present time to the past.

Now, for example, when an abnormality has occurred 100 times since the start of operation, that is, when 200 error history data are stored in the error history memory 2, the operator can press the panel switch 4 to save the error history data. Assuming that a print start command has been issued, the CPU 1 reads data from the page counter area 20 and hour meter area 21 from the error history memory 2, and also reads data from each error history area 221 to 22 ], OO, The characters having the structure shown in FIG. 3 are edited, and further developed into a bit pattern corresponding to this character string and sent to the print section. Then, the printing unit 5 prints the expanded bit pattern data on paper.

In Figure 3, TOTAL PAGE indicates the total number of pages printed, TOTAL HOUR3 indicates the total operating time, and NO1 is a number assigned to each error history data in chronological order of the time of abnormality occurrence, and the error code and paging corresponding to each NO1 are count value.

Hour meter value is shown.

〔Effect of the invention〕

As explained above, each time an abnormality occurs during operation, the present invention collects history data of the abnormality occurrence, including the cause of the abnormality, the total number of pages printed from the start of operation to the time when the abnormality occurred, and the total operating time. Since the error history data is stored point by point and can be printed out when necessary, by collecting the error history during maintenance of operating equipment, it is possible to know one type of error identified from the error code. It is possible to know the number of pages printed during the abnormality from the counter and the operating time from the hour meter, which has the effect of facilitating analysis of the frequency of two cycles of abnormality, etc., and improving maintainability.
