JPS63193225A - Retry control system for printer device - Google Patents

Abstract

PURPOSE:To reduce the halt rate of a printer device and to smooth printing processing by controlling retry operation according to the judgement of the printer device. CONSTITUTION:An error which can not be retried is an error caused when a specific component is short-circuited and a free blows out, and an error which can be retried is an error caused when dot pulses are too many or insufficient. An error judgement part 11 is stored previously with information for judging whether or not an error can be retried corresponding to an error code sent from an error detection part 4, and operation information received from a printing control part 2 is checked by a detection part 4; if an error is detected, it is converted into an error code, which is sent out to the judgement part 11. If it is judged that the error can not be retried, that is reported to the control part 2, the printer device 10 is stopped, and an error display is made on a display part 5. When the error can be retried, a retry operation control part 12 is accessed.

Description

[Detailed Description of the Invention] [Summary] A retry control method for an impact printer device, which stops printing processing operation when a printing error is detected;
In order to solve the problem that the printer is in a hibernation state and requires a restart operation, which increases the outage rate of the printer, detected printing errors are classified into retryable errors and retryable errors. By configuring the printing error that is determined to be a retryable error to be retried by a retry operation control means in the printer, the downtime rate of the printer can be reduced.
This enables smoother operation.

[Industrial application field]

The present invention relates to a retry control method for an impact printer.

For example, automatic transaction equipment (ATM) used in financial institutions, etc.
) Printer devices installed in financial institutions are required to operate reliably and smoothly as holiday operations and unmanned operations at financial institutions increase.

In particular, such printer devices are required to have a system that allows them to continue operating as much as possible even if an error is detected in the printing operation.

[Conventional technology]

FIG. 3 is a block diagram illustrating a conventional example, and FIG. 4 is a diagram illustrating a retryable error.

FIG. 3 shows a functional block diagram of the printer device 1, which is composed of a print control section 2 that controls print processing operations based on print data transferred from a host device (not shown), and a host device (not shown). a data transmitting/receiving section 3 that sends and receives data to and from the printer (not shown); an error detecting section 4 that checks the print data using a predetermined method, detects the presence or absence of an error, encodes the checking status and sends it out; and an error detecting section an error display section 5 that displays an error visually and audibly when an error is detected in step 4; and a print head that drives the print head in accordance with the print data under control from the print control section 2. It includes a drive section 6, a print head 7 that performs printing processing of print data, a motor drive section 8 that drives a space motor 9, and a space motor 9 that sequentially moves the print head 7 in the printing processing direction. It is composed of

When the print control unit 2 confirms the print command and print data transferred from the host device (not shown) via the data transmission/reception unit 3, the print control unit 2 sends the print data to the error detection unit 4. do.

The error detection section 4 checks the presence or absence of an error, and sends the check result back to the print control section 2 as coded information.

Next, when the print control unit 2 confirms that there is no error using the encoded information, it sets print data in the print head drive unit 6,
Instructs the motor drive section 8 to start operating the space motor 9.

Then, the space motor 9 is moved, and the print data that is sent to the rad 7 is printed on a predetermined medium by the space motor 9 moving in the printing direction.

Further, even if an error is detected in the printing operation, the error detection section 4 checks it, and sends the check result back to the printing control section 2 as encoded information.

When the encoded information confirms that there is an error, the print control unit 2 reports the error information to a host device (not shown) via the data transmitting/receiving unit 3 and waits for an instruction.

The types of errors checked by the error detection section 4 include, for example, errors caused by blown fuses, and the error of too many/too few dot pulses as explained in FIG.

Normally, in the printing process, 10 characters per inch or 12 characters per inch and its resolution are specified, and this is checked by pulses obtained with a slit disk (a) as shown in Figure 4 (A). I'm doing it at

That is, the area between the thick lines is a predetermined printing zone, and the area between the printing zones shows dots, and by shining light onto this slit disk (al), for example, a zone waveform and a dot waveform are obtained.

Incidentally, FIG. 4(B) is a diagram showing the relationship between zones and dots in an easy-to-understand manner, and FIG. 4(C) shows the zone waveform and dot waveform obtained thereby.

Further, FIG. 4(D) shows the zone pulse (forming straight line) and dot pulse (governing straight line) obtained by slicing the zone waveform and dot waveform at the zone slice level and the dot slice level.

The number of dot pulses in a zone pulse is determined by the printing resolution, and whether the number of dot pulses becomes too large or too small is treated as an error.

[Problem that the invention seeks to solve]

In the conventional method as described above, if an error is detected in the printer device 1 at -a, the printer device 1 is forcibly terminated, an error is displayed, and the error is reported to a host device (not shown). , and waits for instructions.

While waiting for this instruction, the printer device 1 is in a stopped state, and normally an operator's operation is required to change it from a stopped state to an operating state. Therefore, during unattended operation, the printer device 1 will remain in a stopped state until an operator performs an operation. Become.

Furthermore, since the printer device 1 is put into a hibernation state every time an error occurs, the overall halt rate of the printer device 1 increases, resulting in problems such as impeding smooth operation.

[Means for solving problems]

FIG. 1 shows a block diagram illustrating the invention in detail.

The principle block diagram of the present invention shown in FIG. 1 is based on the print control unit 2. Data transmission/reception section 3゜Error detection section 4
．． Error display unit 5; error determination means (error determination unit) 11 for determining retryable errors and non-retryable errors from the detected error content; and access signals from error determination unit (error determination unit) 11. The retry operation control means (retry operation control section) 12 is configured to control retry operations.

[Effect]

The error determination means (error determination unit) 11 classifies the detected printing error into a retryable error and a retryable error. Error display section 5
displays an error, and displays a retryable error and a printing error determined by the error determination unit (error determination unit) 11, which is immediately retried by the retry operation control unit (retry operation control unit) 12 in the printer device 10. By configuring the printer device 10 to be processed, the downtime rate of the printer device 10 is reduced, and smooth operation becomes possible.

〔Example〕

The gist of the present invention will be specifically explained below with reference to an embodiment shown in FIG.

FIG. 2 shows a block diagram illustrating the invention in detail. Note that the same reference numerals indicate the same objects throughout the figures.

The non-retryable error determined by the error determination unit 11 of this embodiment is, for example, an error when a fuse is blown due to a short circuit in a predetermined component, and the retryable error is
This is the error of too many/too few dot pulses as explained in FIG.

Therefore, this error determining section 11 has an error detecting section 4 in advance.
It is assumed that information for determining whether an error is a non-retryable error or a retryable error is stored in the form of a table or the like in response to an error code sent from the computer.

The error detection section 4 checks the print data and printing operation information received from the print control section 2 using a predetermined method, and if an error is detected, converts it into an error code and sends it to the error determination section 11.

The error determination unit 11 compares this error code with a table or the like and determines whether the error is a non-retryable error or a retryable error.

If it is determined that the error is a non-retryable error, the error determination section 11 notifies the print control section 2 to that effect, stops the operation of the printer device IO, and displays an error display section 5 via the error detection section 4. Displays an error.

If it is determined that a retryable error has occurred, the print data is reset to the print head drive unit 6 via the print unit 2, the mode drive unit 8, etc., and a retry operation is immediately performed.

〔Effect of the invention〕

According to the present invention as described above, by performing retry operation control based on the judgment of the printer device, the downtime rate of the printer device can be reduced and printing processing can be performed more smoothly.
