Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a copying machine, a facsimile,
Related to the job recovery control device for recording devices such as printers,
In particular, the present invention relates to a job restoration control device suitable for restarting a job based on the stored job contents when a failure occurs.

[0002]

2. Description of the Related Art Conventionally, in a recording apparatus which controls a recording operation by using a microprocessor, when a trouble such as a paper jam occurs, the recording operation is urgently stopped to output a solution for the trouble, and the operator is caused to have the trouble. The recording operation can be restarted after the problem is solved. On the other hand, when the operator detects a failure that cannot be resolved, the recording operation is stopped suddenly, the failure detection signal is stored in the memory, and a serviceman call (call the person to be repaired) is output to output all inputs. Reception is prohibited.
Then, the power is turned off / on (returned on) so that the microprocessor performs an initialization operation to clear the memory so that the failure diagnosis mode input can be accepted. Therefore, after the failure was recovered, the continuation of the job was set again.

Further, as a measure against power supply abnormality, for example, in Japanese Patent Laid-Open No. 58-220166, the recording operation is stopped immediately in response to the occurrence of an abnormal power supply state to prevent the auxiliary power supply from resetting the microprocessor. A technique is disclosed in which a suspended copy job can be restarted after the recovery of the power supply state, and Japanese Patent Laid-Open No. 63-118962 discloses processing data by interrupting the processing of a microprocessor when a power supply voltage drop is detected. Is stored in the nonvolatile memory and the power is turned on again to read the processing data from the nonvolatile memory and restart the interrupted processing of the microprocessor.

[0004]

When a failure occurs, as a conventional measure, it is designed so that the machine does not operate unless the power of the machine is turned off, the failure is corrected, and then the power is turned on again. At this time, in the control system of the machine, the initialization is performed by turning the power off, then on.
All data in the middle of the job is cleared. For example, in optical reading scanning, if the carriage does not move to a predetermined position within a predetermined time due to some reason such as being caught, it may be considered as a failure in control. In such a case, turn off the power once,
When it is turned on again, memory initialization and failure diagnosis of each part of the machine are performed, and if the carriage moves to a predetermined position within a specified time, the failure diagnosis result may be normal and may return to normal. However, in the case of failure detection due to a control abnormality such as detection of an abnormal state in which the original scanning time has exceeded, the power is turned off / on.
Therefore, the RAM is cleared to set the priority mode and the set number of sheets, and the interrupted job cannot be restarted.

Further, in the method of restarting the interrupted processing of the microprocessor, for example, a failure due to a control abnormality such as detecting an abnormal state in which the original scanning time is exceeded immediately before the driving command output of the sheet feeding means during continuous copying is detected. In case of detection,
The process is restarted from the drive command output process of the paper feeding unit, which is the process of the microprocessor interrupted by turning on the power again. However, this control is not suitable for resuming an interrupted copy job because there are papers left in the machine at the time of the interruption and these papers need to be removed or the sensitive material needs to be cleaned. ..

As other failures, in communication between CPUs, when data is not transmitted / received as specified, or when communication fails due to disconnection, or the speed of the photosensitive belt deviates beyond an allowable range. There is a similar problem depending on the situation. SUMMARY OF THE INVENTION An object of the present invention is to provide a job recovery control device for a printing apparatus, which can resume the remaining jobs in the setting state when the failure occurred after recovery from the failure in controlling the printing operation.

[0007]

In order to achieve the above object, a job restoration control device of a recording apparatus according to the present invention has a first non-volatile memory and a second non-volatile memory, and a recording operation condition of the recording apparatus. Setting means, a recording operation control means for controlling the recording operation based on the recording operation condition set in the setting means, a failure detection means for detecting a failure of the recording operation control means, and the failure detection means. The recording operation mode of the recording operation control means and the progress of the recording operation are stored in the first non-volatile memory by the detection signal, and the detection signal of the failure detection means is stored in the second non-volatile memory, and When the detection signal of the failure detection means is stored in the second non-volatile memory when the power is turned on, the operation prohibiting means for prohibiting the operation of the recording operation control means is stored in the first non-volatile memory. That the progress of the recording operation mode and the recording operation is re-set in the setting means is for and a return control means for canceling the operation prohibition of the recording operation control means by said operation inhibiting means.

[0008]

When a failure occurs while the recording operation control is being performed based on the recording operation condition set in the setting means, the recording operation mode and the progress status of the recording operation are stored in the first nonvolatile memory, The detection signal of the failure detection means is stored in the second nonvolatile memory, and the operation of the recording operation control means is prohibited. When the detection signal of the failure detection unit is stored in the second nonvolatile memory when the power is turned on, the setting unit based on the recording operation mode stored in the first nonvolatile memory and the progress status of the recording operation. Since the operation prohibition of the recording operation control unit by the resetting and the operation prohibiting unit is released, the recording operation can be restarted based on the reset recording operation condition at the time of occurrence of the failure.

[0009]

Paper is sorted.

The hardware configuration of the copying machine will be described with reference to FIG. The user interface (UI) controller 30 manages data related to device specifications of the M / C, so-called config information, and is set / input to perform a recording operation by a button operation on the console panel 12a of the UI 12. Main control system (MAIN PWBA: hereafter referred to as “MAI” that executes processing based on the config information for data (copy mode information) and manages the system of this machine.
The input data is sent to the display device CRT1 and information such as copy mode, recording operation, and fail is displayed.
2b is displayed.

Further, in the UI, the job information generated by the job restoration control is received by the start instruction command from the same UI as usual, data processing for executing the restoration control job is performed, and the same operation as a normal start can be performed. ..
The above hardware has an independent CPU for each function, and an electric circuit board (PWB
A) is configured.

Next, the job return control will be described.
2 to 4 show an outline of processing of job restoration control according to the present invention. Here, the machine (M / C) when the failure occurred
When the state command (STAND-BY) is received, the fail command (FAIL CMD) is received while the M / C is stopped, and the UI is M
When a communication failure with AIN is recognized, it is used as a job save trigger (trigger), and when this trigger occurs, it is determined whether or not to perform job save.

FIG. 2 shows an outline of processing when the power is off. When a fail occurs, the fail information file is referred to in the fail judgment processing, and it is checked whether or not there is a fail that is not registered in the job save and is registered in advance. As a result, if the fail is to be saved, the current recording mode information is saved in the recording mode of the nonvolatile memory (NVM) in the user interface UI in the mode registration process (recording mode save information), and the recovery information is also saved. Is saved, and the fact that the job has been saved is recorded by a flag “ON” (job save information), and then the power is turned off and the power is turned off.

Here, the recording mode information is, for example, magnification information, density information, editing information, erase information in a copying machine,
The binding information is the binding margin information, and the recovery information is information indicating the progress of the job, that is, information for continuing the remaining jobs at the next start after the M / C is stopped. (Count) information, the number of originals (skip) information for controlling the ejection of the documents that have completed image formation without scanning, and the process of ejecting the paper remaining in the device during image formation when a failure occurs. The information includes the number of originals to be returned when the originals whose reading has been completed are returned to restart the job.

In the present embodiment, the fail information not to be saved as a job is listed as a fail information, and the number of data to be compared and compared is reduced by checking the coincidence between this fail and the generated failure so that the job save judgment process can be performed quickly. You can FIG. 3 shows an outline of processing at power-on. As the mode to be powered on again after powering off, the user (USER) mode for the user to perform normal recording operation, and for the service person to check the cause of the failure, for example, check the sensor level or move something. Machine to check its movement (M / C)
There is a failure diagnosis (DIAG) mode for checking the abnormality of M / C and a user diag (USER DIAG) mode for checking the abnormality of M / C in the normal recording operation.

Therefore, it is necessary to check the power-on condition to which the present invention applies in these modes.
That is, first, the system state (SYS STATE) is USER
Alternatively, it is determined whether it is DIAG or USERDIAG, and when the power-on system state (USER) is received by the user, mode call determination processing is performed. In this mode call judgment processing, job save information, configuration information,
It is determined from the recovery information whether or not to call the recording mode. The config information is, for example, DADF, as M / C specification setting information written at power-on.
There are data such as RDH and developing device (option).

When executing the saved recording mode in the mode call judgment process, if the configurations match and the mode is not the access mode, it is judged that the mode is executable (OK) and the mode call process is started. Further, if there is no job save information due to the normal termination of the previous job or if the job according to the job save information is unsuitable from the current M / C status, it is judged to be unexecutable (NG), and normal processing is performed. Once this normal process is executed, the job save information is cleared (flag OFF). Here, the access mode refers to a mode in which the recording device can be used only when the user inputs a user code.

Upon receipt of the executable (OK) notification from the mode call judgment process, the mode call process loads the record mode save information saved in the non-volatile memory into the record mode and sets this record mode. .. In the determination of the system state at the time of power-on, when the diagnosis mode which is the failure diagnosis mode shown in FIG. 4 is determined, the normal processing in the diagnosis mode is performed. In this case, the job save information is cleared. In this example,
The job save information is cleared when the normal processing or the failure diagnosis processing in the diagnostic mode or the user diagnostic mode is executed at the time of power-on by re-input, but it may be configured not to be cleared.

Next, the job return control will be described in detail. 5 and 6 show flowcharts of the recording operation of the recording device. In the recording operation routine, the power is turned off.
If the answer is N, the self-diagnosis processing is started, and a failure that hinders the execution of the recording operation, such as a failure of the electric circuit board, a failure of the mechanical section, or a failure of the communication function, is diagnosed (S1), and the result is determined. Based on this, it is determined whether a failure has occurred (S2). If there is no failure, communication is exchanged that must be performed while the M / C is stopped (S3). It is checked whether a failure has occurred during this transmission / reception (S4). When a failure is determined in S2 and S4, a process of inhibiting the operation of the recording operation control is executed (S9). In S4, if it is not determined that a failure has occurred, it is determined whether the start button has been pressed (S5). If not, the process returns to the stopped process (S3). When it is confirmed by the recording operation start signal that the start button has been pressed, the UI
The recording operation mode input and stored in 12 is set, and the recording operation process is performed (S6). That is, the recording operation for forming an image is started based on the image information read from the document, and the recording operation state (progress of the recording operation) at this time is stored.

The failure during the recording operation process is monitored (S
7) When the failure of the recording operation is not detected, the completion of the recording operation is judged (S8), and when the recording operation is abnormal, the operation of the recording operation control is prohibited (S9). When the recording operation is completed, the process returns to S3 to wait for the input of the next job. On the other hand, if the recording operation is in the middle, the process returns to S6 to update the progress status of the recording operation at this time. When the recording operation control is prohibited, the set recording operation mode and the progress status of the recording operation stored during the recording operation processing are stored in the first nonvolatile memory (S1).
0), the second failure detection signal as the failure determination result in S7
The data is stored in the nonvolatile memory (S11). After that, the power is turned off.

In the job restoration routine, when the power is turned on again (power on), it is checked whether or not the failure detection signal is stored in the second nonvolatile memory (S12).
If not stored, the initial value (default mode) is set in the setting means (S13), and the process returns to S1 to execute the recording operation control. When the failure detection signal is stored, the recording operation mode of the first nonvolatile memory and the progress status of the recording operation are set in the setting means (S14), the operation inhibition is released, and the recording operation control is started. The job after the job is stopped is executed.

Next, the job return control applied to the copying machine will be described. 7 and 8 show flowcharts from the occurrence of a fail to the power off. MAIN
When the UI receives the M / C information sent from the system, in the UI communication management, command interpretation and communication monitoring are performed to determine the occurrence of a job save determination trigger based on command reception and the presence or absence of communication failure. M / C for confirming whether M / C is moving or stopped
It is determined whether the C-state command (M / C STATE CMD) or the fail (FAIL) command is received (S100).

When the fail command is received (S10
1) As the generation of fail (JFAIL) information in the recording operation, the CONSTATE information is updated to the fail state (FAIL STATE), and the type of fail is registered (S102). If the received M / C state command is standby (STAND-BY) (S103), M / C is generated as the standby state (STAND-BY STATE) is generated.
The state information is updated to the standby state (S10
4). When a communication failure is detected (S10
5), the state information is updated to the fail standby state to generate the fail (JFAIL) information, the communication system fail is registered (S106), and the M / C state information is updated to the standby state to generate the standby state (S106). S107).

After it is determined that the job save is to be performed, and the occurrence information of the trigger at that time is generated, the condition determination of the job save is performed. First, the system state (SY
It is determined whether (S STATE) is USER (S108), and if the power is turned on by the user, it is determined whether the M / C is stopped. That is, the M / C is either a standby (STAND-BY) that recognizes the recording operation process, a purge standby (PRG STAND-BY) that recognizes the paper discharge process, or a jam (JAM) that recognizes a paper jam. It is determined whether the vehicle is in the stopped state due to (S109, 110, 111).

It is judged whether the M / C is stopped (CON STATE) and the fail is recognized (S112). If the fail is recognized, it is checked whether the power-on sequence of the CPU is completed (S113). .. That is, since the process of transferring the non-volatile memory (NVM) information to the CPU is performed at power-on, it is checked in S113 that this process is completed. When the above process is completed, it is determined whether the tools information is being changed (input) using the tools function on the console panel (S114). Since a failure may occur during the tool input, the process of S114 is performed to improve the reliability of the fail confirmation. Here, the tools information is written in the NVM and is information that can be changed by a casual operator such as a preheating time for power saving and a paper tray used first when the power is turned on.

If the tools are not being input, a system fail determination process is performed (S115). Here, the paper tray of a certain stage becomes unusable, the servo motor of the automatic document feeder fails, and it stops working, and the drive mechanism of the stacker and stapler fails and becomes unusable. In the copy mode where the job can be executed without using itself or other things, for example, a fail (local fail) where the job can be executed by using a paper tray or device is defined in the ROM table as fail information, It is searched whether the fail that is being performed is in the local fail. If it is not in it, it is determined that a fatal fail (system fail) has occurred.

As a result of the failure judgment, if it is necessary to register the mode, copy mode information, various recovery information and job save information are set. In this embodiment, the eleventh main body memory provided as a job memory for preliminarily registering and storing ten types of copy modes such as frequently used copy mode information and copy mode information for a specific user. I will use it to register the job save. First, the copy mode information is set in the intermediate memory (S116), and the contents are registered in the main body memory (S117). And registration No. “11”
Is registered in the main body memory as an index (S11
8). For example, if a failure occurs during the operation of the interrupt job, the interrupt save information is updated to the copy mode, and the job is saved in the copy mode before the interrupt. By providing the intermediate memory, it can be shared with the job memory registration processing, the processing efficiency can be improved, and the ROM capacity can be reduced.

Subsequently, in addition to the information registered in the main body memory, in the job save, a recovery information save process is performed to recover the job at the time of calling. In this process, it is first judged whether or not the recovery command (RCVRY CMD) generated and sent by the MAIN system when a failure occurs is received (S119), and then the automatic document recirculation feeder (RDH) is in the collate mode. (S12
0), in the collate mode, the recovery information is saved (S122). If no recovery command is received or the RDH is not in collate mode,
The number of copied sheets output after the image formation is counted, the maid count (MADE COUNT) of the internal memory storing it is cleared (S121), and the recovery information is saved (S122). After turning the job save information "ON" (S123), the power is turned off.

Here, the recovery command is originally for displaying the failure occurrence status. If, for example, a jam occurs during the failure occurrence, the main body side corrects the jam, that is, returns the number of sheets before the job is executed. I'm doing something to do. In this way, the recovery command is used when deciding from which point the recovery should be started. The collate mode is a copy mode in which a certain number of originals are set so that a plurality of copies are made.

For the maid correction, if a failure occurs in the RDH mode and the number of originals R / the number of set sheets L = 5 and MADE = 3, the M / C is stopped and a jib save is executed. The maid count at this time is saved as "3".
After that, the power is turned off and the failure diagnosis is performed. When power is turned on after recovery from failure, RDH mode, R / L = 5, MA
When DE = 3, Jib is called and the copy operation processing is restarted. In this embodiment, the RD is used as the determination condition for mode registration.
Although only the H collate mode is used, this is merely an example, and it goes without saying that the usage conditions of other accessory devices may be added or added.

The recovery information includes maid count, job status (JOB STATUS), configuration information (input / output (INPUT / OUTPUT) device presence / absence and type / HCF presence / absence / developing device (option: 2ND DEVE) ) Presence / absence / tandem presence / absence), user number and input mode. Here, the job status indicates the state of the job, and manages the job completion indicating that the job is not executed and the job incomplete indicating that the job is in the middle. The input mode includes a platen mode, a slot use mode, an automatic document feeding use mode, and the like, and is information about where a document is located and how to control the copy.

9 to 11 show flowcharts from power-on to mode call. When it is determined that the system state is neither the diagnosis mode nor the user diagnosis mode (S200, 201)
Manages to receive only necessary reception information (reception management). In either of the diagnosis mode and the user diagnosis mode, the job save information is cleared (S202), and then reception management is performed.

It is confirmed whether the NVM information has been transferred to the CPU (S203). If the transfer completion notice is received, the configuration information is fetched (S204). Next, it is checked whether the job save information is "ON" (S205). If it is ON, the config information is compressed and converted into information for checking, for example, 3 Byte → 1 Byte (S206). It is determined whether the converted configuration information matches the configuration information of the recovery information (S207), and if they match, the access mode is determined. If they do not match, job recovery is not performed, so the job save information is cleared (S2
08), and proceed to the determination of the access mode (S209).

If the access mode is selected, the AUDITRON screen is displayed (S21).
2). When not in access mode, assign (AS
(S210), if it is the assign mode, after confirming that the job save information is "ON", that is, there is a job save (S211), the user sets the user code. Move on to the Auditron screen display for entering. Here, the assign mode is a mode in which the user can use the copying machine without inputting a user code. In this mode, when the user code is input, the copy amount of the user is counted, and when the user code is not input, the copy amount is not counted.

If the mode is neither access nor assign, it is judged whether the job save information is "ON" (S213), and the job is saved (ON).
(State), perform a job save calling process (S21
4) Execute normal (NORMAL) mode. When the job is not saved (0FF state), the default (DEFOLT) mode calling process registered in advance as the standard mode is performed (S215), and the normal mode not using the auditron is executed. When the user performs an input operation using the Auditron screen, the input data is interpreted by the input management function of the UI. First, it is determined whether the all clear key is pressed (S213), and when it is pressed, it is determined whether the assign mode is selected (S21).
4).

If the assign mode is not set, the process returns to the input management. On the other hand, when the all clear key is not pressed, it is determined whether the user number (NO) is input and whether the "A" key is pressed (S216). If YES, the input user number is set, for example. The validity of whether or not it is a numerical value of the number of digits is checked (S217). S
At 216 and 217, if NO, an invalid (IN
VALID) is displayed (S218).

If the entered user number is valid, it is checked whether the job save information is "ON" (S219), and if there is a job save (ON state), the job save information is saved. Clear information (O
FF) (S220). The user number is determined (S2
21) If it is the registered user number, the save mode call processing is performed (S222), and the copy operation in the auditron mode is executed. When there is no job save information in the assign mode (S211), when the all clear key is pressed and the job save information is cleared in the assign mode (S215), when there is no job save information in the user number judgment (S219) and the user number is If they do not match (S221), the default mode calling process is performed (S223), and the copy operation in the auditron mode is executed.

12 to 16 show flowcharts from the mode calling to the start. The save mode calling process includes the copy mode saved in S116 to 118 and the recovery information saved in S112. First, the calling number of the main body memory is set to "11" (S300), and the contents of the main body memory are set to the intermediate memory (S301). After setting the contents of the intermediate memory and the recovery information in the copy mode information (S302, 30
3), the job save information is cleared (S304), and information on whether or not the job save call is made will be described later in S31.
Set "ON" with reference to 2, 322 and 332.
A so-called flag is set (S305). On the other hand, in the default calling process, the default mode is set in the copy mode information (S306).

After the setting process of S305 or S306, the interpretation by the reception and input management function while the M / C of the UI described below is stopped is performed. That is, machine state (M / C STATE) standby (STAND-BY)
If is received (S310), a standby state (STAND-BY STATE) is created (S311). Next, it is determined whether the job save call information is set (S312), and when it is ON, the job status (JOB STATUS) indicating that the job is not executed is "JOB".
"COMP" is sent to the MAIN system. When the job save call information is OFF, the job status is "JOB COM
If it is "P" (S314), if it is "JOB COMP", it proceeds to the processing of S313. If it is not "JOB COMP", "JOB INCOMP" is set as the job status indicating that it is in the middle of a job. (315).

If there is "TRAY STATUS DPX" paper indicating the status of the double-sided copy tray used in the double-sided copy mode, and the guide operation status is received (S320), the paper tray information is updated (S321). , It is judged whether the job save call information is set (S322),
When it is ON, the duplex purge flag (DPX PURGE FLAG) for discharging the paper is set (S32).
3). When the job save call information is OFF, it is determined whether the job status is "JOB COMP" (S3
24) In the case of "JOB COMP", after the duplex purge flag is set (S325), a message to the effect that the paper discharge process in the duplex mode is performed is displayed (S326).

An input tray status (INPUT TR
If (AY STATUS) is received (S330), after updating the input tray information indicating the storage location of the received "INPUT TRAY STATUS" data (S331),
It is determined that the job save call information is not set (S332), and if it is OFF, it is determined whether the job status is "JOB COMP" (S333) and "JOB CO
In the case of "MP", an input mode is created (determined) based on the input tray information (S334). When the clear key or the all clear key is pressed (S34)
0), clear the copy mode information and the job save call information (S341, 342). When the start key is pressed (S350), the job save call information is cleared (351). Then, the copy control process is executed.

In the embodiment, when the recording operation mode and the progress status of the recording operation stored in the non-volatile memory are reset in the setting means, the configuration information after the power is turned on is stored in the non-volatile memory. Since it is determined whether or not the existing recording operation mode can be executed and the resetting is performed, it is possible to prevent the control from being lost after the resetting. Furthermore, in making that decision,
Judgment can be speedy and easy because the judgment is made based on the match between the config information at the time of failure occurrence and the config information after power-on. In addition, the failure detection means identifies whether the generated failure is a failure that can be recovered by the user, such as paper jam or lack of toner, or a failure, and further detects whether the failure is a local failure or a system failure. The operation of the recording operation control means is prohibited according to the degree of abnormality.

Further, the operation prohibiting means executes the operation prohibiting of the recording operation controlling means depending on whether or not the detection signal of the failure detecting means is stored in the non-volatile memory, and the return control means at the time of turning on the power supply has the non-volatile state. Since the operation prohibition is released by clearing the detection signal of the memory, control is easy. In addition, since the failure detection means operates even when it is stopped, even if the self-diagnosis function operates when the power is turned on and a failure occurs, the operation prohibition means operates again, and the recording operation at the time of failure detection when the power is turned on. Since the resetting can be performed based on the condition, the recording operation can be restarted based on the resetting recording operation condition at the time of occurrence of the previous failure when the failure is recovered.

As described above, according to the present invention, since the M / C stores the mode information when a failure occurs, it is not necessary to set the mode again. In addition, the progress of the job is M / C
Memorizes and automatically recovers, so there is no danger of outputting extra records.
