The CPU 31 acquires attribute of a job stored by the RAM 33 when the CPU receives total cancel command for cancelling all jobs from the operation panel 40. In addition, when there is no job having different attribute among the all jobs stored in the RAM 33, the all jobs stored in the RAM 33 are cancelled. When there is a job having different attribute, only jobs having specific attribute are cancelled, jobs having no specific attribute are not cancelled.

Description

  The present invention relates to an image forming apparatus. More specifically, the present invention relates to an image forming apparatus capable of receiving a plurality of jobs.

  2. Description of the Related Art Conventionally, a technique is known in which an image forming apparatus can accept a plurality of jobs and cancel a job being executed or a job on standby. As a document disclosing a technique for canceling a job, for example, there is Patent Document 1. In Patent Literature 1, when a job execution stop instruction is received, if there is a single received job, the job is canceled, and if there are a plurality of received jobs, the job to be canceled is selected and selected. A job processing apparatus that executes cancellation of a job is disclosed.

JP 2010-284920 A

  However, the conventional technique described above has the following problems. That is, it is inconvenient for the user to select all of his / her own jobs while other users' jobs are mixed when he / she wants to cancel all of his / her specific jobs. On the other hand, providing a function for canceling all jobs causes a problem because jobs of other users are canceled.

  The present invention has been made to solve the above-described problems of the prior art. That is, an object of the present invention is to provide an image forming apparatus that can execute cancellation of a specific job by a simple operation.

  An image forming apparatus designed to solve this problem includes a forming unit that performs image formation, a receiving unit that receives an operation input, a storage unit that stores a job instructed to be executed, and a control unit. The control unit acquires the job attributes stored in the storage unit, and receives a cancel instruction for canceling all jobs by the reception unit. If there is no job having a different attribute, all the jobs stored in the storage unit are canceled. If there is a job having a different attribute, only the job having a specific attribute is canceled, A feature is that jobs that do not have a specific attribute are not canceled.

  The image forming apparatus disclosed in the present specification acquires job attributes stored in the storage unit when an all cancel instruction for canceling all jobs is received. The acquired attribute may be at least one type of job attributes, for example, a user name or a print file name. If the attributes of all jobs stored in the storage unit match, all jobs are canceled. On the other hand, when there are jobs having different attributes, not all jobs are canceled, but only jobs having specific attributes are canceled. Jobs without specific attributes are not canceled.

  According to the image forming apparatus disclosed in the present specification, when there is a job having a specific attribute among jobs to be canceled by an all cancel instruction, only the job having the specific attribute is canceled. To do. On the other hand, jobs other than jobs having the specific attribute are not canceled. As a result, it is possible to avoid canceling a job that is not related to the job that the user originally wants to cancel. Therefore, canceling a specific job can be executed by a simple operation.

  In addition, when the control unit receives the cancel instruction, the storage unit does not store the attributes of subsequent jobs that are continuously received and the attributes of the canceled job. If so, the subsequent job may be canceled. Even if it is not stored in the storage unit when all cancel instructions are received, if it is a succeeding job that has been continuously received, the sending device has already issued a job print instruction at the time of all cancel instructions. It is likely that it was. For example, a job waiting on the transmission source device due to the memory full of the image forming apparatus is accepted after the cancel instruction because the memory is freed by cancel processing. It is preferable for the user that such a job is included in the target of all cancellation instructions. Therefore, even if the job is received after the cancel instruction, it is preferable to cancel the job if it has the same attribute as the cancel target. Note that if the attribute of the succeeding job is different from that of the canceled job, it will not be canceled. Jobs that are not subject to cancellation may be executed immediately or after cancellation processing.

  In addition, when the job stored in the storage unit includes a job having a different attribute, the control unit may cancel a job having the same attribute as the job being executed as the specific attribute. Good. There is a high possibility that the user who has instructed all cancel instructions is the user of the job being executed. For this reason, it is preferable to cancel a job having the same attribute as the job being executed and not cancel a job having a different attribute.

  In addition, when the job stored in the storage unit includes a job having a different attribute, the control unit accepts input of the attribute of the job to be canceled and is input as the specific attribute. A job having the same attribute as the attribute may be canceled. By allowing the user to input an attribute to be canceled, the possibility of canceling the job desired by the user increases. Further, it is possible to suppress cancellation of an undesired job.

  Further, the control unit is not stored in the storage unit when the all cancel instruction is received, and among the succeeding jobs continuously received, the time before the time when the all cancel instruction is received. If the attribute of the subsequent job is the same as that of the canceled job, the subsequent job is canceled and the execution instruction is issued after the time when all the cancel instructions are accepted. Canceled jobs may not be canceled. If the job is instructed to be executed before the time when all cancellation instructions are received, the job may be subject to cancellation by the all cancellation instructions in the same manner as the job stored in the storage unit when all cancellation instructions are received. preferable. An example of such a job is a job that has been waiting on the transmission source device due to the memory full of the image forming apparatus.

  In addition, when the control unit receives the cancel instruction, the storage unit does not store the attributes of subsequent jobs that are continuously received and the attributes of the canceled job are different. For example, the subsequent job and the job received after the subsequent job need not be canceled. If there are jobs with different attributes among subsequent jobs that have been received consecutively, it is preferable not to cancel subsequent jobs. It is also possible to inquire the user to cancel the cancel processing and stop it after obtaining confirmation.

  The image forming apparatus disclosed in the present specification may include an acquisition unit that acquires user information. According to the acquisition unit, user information can be acquired with certainty. Note that, for example, a login state corresponds to a state in which user information is acquired.

  In addition, when there is a job having a different attribute among the jobs stored in the storage unit, the control unit has a job having the same user information as the user information acquired by the acquisition unit as the specific attribute. It is good to cancel. When user information has been acquired, there is a high possibility that the user has input all cancellation instructions. For this reason, even if all of the user's jobs are canceled, inconvenience hardly occurs.

  Moreover, the said control part is good to receive the said all cancellation instruction | indication, when the user information is acquired by the said acquisition part. When user information is not acquired, it is difficult to identify a user who has input all cancellation instructions. Therefore, it is preferable to limit acceptance of all cancellation instructions to a state in which user information has been acquired.

  According to the present invention, an image forming apparatus that can cancel a specific job by a simple operation is realized.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an image forming apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. In this embodiment, the present invention is applied to a printer having an image forming function.

[Electrical configuration of printer]
The printer 100 according to the embodiment is used by being connected to a PC 200 and a server 300, for example, as shown in FIG. The printer 100 may be connected to either the PC 200 or the server 300, or may be connected to more devices.

  The printer 100 includes an image forming unit 10, a main controller 30, an operation panel 40, and a network interface 37. The image forming unit 10 forms an image on a sheet. The image forming method of the image forming unit 10 may be an electrophotographic method or an ink jet method. Further, even if a color image can be formed, it may be dedicated to a monochrome image. The image forming unit 10 is an example of a forming unit.

  The network interface 37 is connected to a network such as a LAN. The printer 100 is connected to a PC 200, a server 300, and the like in which a printer driver is incorporated by a network interface 37. The printer 100 receives input of a print job and various commands via the network interface 37. The operation panel 40 includes input keys, display members, and the like, and accepts direct input operations by the user. The network interface 37 and the operation panel 40 are both examples of a reception unit.

  As shown in FIG. 1, the main controller 30 includes a CPU 31, a ROM 32, a RAM 33, an NVRAM (nonvolatile RAM) 34, and an ASIC 35. The main controller 30 is electrically connected to the image forming unit 10, the operation panel 40, and the network interface 37.

  The ROM 32 stores various control programs for controlling the printer 100, various settings, initial values, and the like. The CPU 31 controls each component of the printer 100 according to a control program read from the ROM 32, a signal sent from the operation panel 40, and the like. The CPU 31 is an example of a control unit. The main controller 30 may be a control unit, and the ASIC 35 may be a control unit.

  The RAM 33 is used as a work area from which various control programs are read or as a storage area for temporarily storing various data. The RAM 33 stores received print job data, for example. The RAM 33 can store data for a plurality of print jobs. The RAM 33 is an example of a storage unit. The NVRAM 34 stores various setting values.

[Print Job]
The printer 100 receives various instructions such as a print instruction and a cancel instruction via the network interface 37 or the operation panel 40. The print job 50 included in the print instruction is data including job information 51 and print data 52 as shown in FIG. The job information 51 includes a plurality of information related to job attributes. Attributes included in the job information 51 include, for example, a reception date and time 54, a user name 55, a file name 56, a transmission device 57, and a print setting 58. The print data 52 is print image data.

  The job information 51 stores individual information regarding the print job 50 for each attribute. For example, the reception date and time 54 stores the date and time when the job was instructed to be executed. The user name 55 stores identification information of the user who has instructed the job. The file name 56 stores the file name related to the print data of the job. The transmission device 57 stores the identification information of the device that transmitted the job to the printer 100. The print setting 58 stores information such as print paper and the number of print pages.

  The printer 100 stores the received print job 50 in the RAM 33 in the order of reception. Then, the printer 100 executes the printing operation of the print job 50 stored in the RAM 33 in the order stored in the RAM 33. Further, the printer 100 deletes the print job 50 that has been printed from the RAM 33. Hereinafter, the print job 50 stored in the RAM 33 is referred to as an internal job.

  On the other hand, the storage capacity of the RAM 33 of the printer 100 is limited. In a memory full state where a new print job 50 cannot be added to the RAM 33 and stored, the printer 100 cannot accept the new print job 50. In this case, the PC 200 or the like that is trying to transmit the print job 50 waits for transmission of the print job 50 until the printer 100 is ready for reception. Hereinafter, a print job 50 that has been input with a print command to the printer 100 in the PC 200 or the like but has not yet been stored in the RAM 33 is referred to as an external job.

[Cancel instruction]
The printer 100 accepts a cancel instruction. The cancel instruction is an instruction to delete the received print job 50 by stopping the operation before or during execution. The user can input a cancel instruction from the operation panel 40 or from the PC 200 or the like via the network interface 37.

  The printer 100 accepts an individual cancel instruction and a full cancel instruction as cancel instructions. The individual cancel instruction is an instruction to specify and cancel an individual print job 50. The all cancel instruction is an instruction to cancel the jobs stored in the RAM 33 collectively. In the all cancel instruction, not only an internal job but also a subsequent external job may be canceled. The entire cancel instruction may be input by pressing one dedicated button, or may be input by long-pressing a cancel key or a plurality of continuous operations.

  Specifically, when the printer 100 of this embodiment receives an all cancel instruction, the printer 100 does not necessarily cancel all the internal jobs, but selectively cancels the internal jobs that satisfy the conditions. The printer 100 determines whether or not to cancel the print job 50 based on at least one of various attributes included in the job information 51 of the print job 50. Hereinafter, an attribute used as an index for determining whether or not to cancel in the printer 100 is referred to as a cancel index. For example, the user name 55 and the file name 56 correspond to the cancel index.

  When the printer 100 receives all cancel instructions, the printer 100 selectively cancels the print job 50 specified by the content of the cancel index among the jobs received so far. Hereinafter, the content of the cancel index in the print job 50 to be canceled is referred to as cancel information. For example, when the print job 50 stored as “user A” in the user name 55 is selectively canceled, the cancel index is the user name 55 and the cancel information is “user A”. The cancellation index is an example of an attribute, and the cancellation information is an example of a specific attribute. Specific processing will be described later.

  Note that the printer 100 can accept a login by a user operation. A user who logs in to the printer 100 can occupy the input from the operation panel 40 of the printer 100 and the external connection between the printer 100 and the server 300 or the like. That is, other users cannot operate the operation panel 40 while one user is logged in.

  When accepting a login by a user operation, the printer 100 acquires user information of a user who requests the login. The printer 100 permits login when the user information stored in the NVRAM 34 or the like of the printer 100 matches the acquired user information. Examples of user information include a user name, a user ID, and a password for authentication. The operation panel 40 or the network interface 37 that acquires user information is an example of an acquisition unit. If the printer 100 has an IC card reader, user information can be read from the user's ID card or the like. This IC card reader is also an example of an acquisition unit.

[All cancellation processing]
Next, the procedure of all cancellation processing will be described with reference to the flowchart of FIG. This all cancellation process is executed by the CPU 31 when an all cancellation instruction is accepted.

  When the entire cancel process is started, the CPU 31 executes a cancel index determination process for determining an attribute to be a cancel index (S101). The procedure of the cancellation index determination process will be described with reference to the flowchart of FIG.

  When the cancel index determination process is started, it is first determined whether or not there is a user logged in to the printer 100 (S201). If there is a logged-in user (S201: Yes), the user name is determined as a cancellation index (S202). Further, the user name of the logged-in user is determined as cancellation information (S203). If there is a logged-in user, the user who instructs all cancellations is likely to be the logged-in user. Therefore, if there is a login user, the user name of the login user is used as cancellation information. After S203, the cancel index determination process ends.

  If there is no logged-in user (S201: No), it is determined whether or not an attribute as a cancellation index is set in advance (S204). For example, the administrator of the printer 100 sets the cancel index, and the set cancel index is stored in the NVRAM 34. If the cancel index is set (S204: Yes), the set attribute is determined as the cancel index (S205). After S205, the cancel index determination process ends. Note that the cancel index includes, for example, a user name, a print file name, and a transmission device.

  On the other hand, if the cancel index is not set (S204: No), the print file name is determined as the cancel index (S206). For example, when a plurality of copies are printed for the same file, a print job having a common print file name may be repeatedly sent several times. It is highly possible that a plurality of jobs having the same print file name are desirably canceled together with all cancel instructions. After S206, the cancel index determination process ends.

  If the printer 100 is logged in, it is presumed that only the logged-in user is permitted to operate the operation panel 40, and the user who has input all cancel instructions is the logged-in user. For the logged-in user, the printer 100 obtains user identification information. On the other hand, when the printer 100 is not logged in, the user identification information is not obtained, and the user who inputs the entire cancel instruction is unknown.

  Therefore, if the user is not logged in, the entire cancel instruction itself may not be accepted. In other words, all cancellation instructions may be accepted only when there is a logged-in user and user identification information is obtained. That is, when it is determined No in S201, the cancel indicator determination process may be terminated and the entire cancel process may be terminated.

  When the cancel index determination process in FIG. 4 is completed, the process returns to the all cancel process in FIG. 3 and the contents of the cancel indices are acquired for all jobs stored in the RAM 33 (S102). Here, the cancel index for acquiring the content is determined in the cancel index determination process of S101.

  Next, for all the internal jobs, it is determined whether or not the contents of the cancel index match each other (S103). If the contents of the cancel index match for all internal jobs (S103: Yes), all internal jobs are canceled (S104).

  For example, if the cancel index is the file name 56 and the contents stored in the file name 56 are common in the job information 51 of all internal jobs, the contents of the cancel index of all the internal jobs are one. Judge that you are doing. Then, all jobs stored in the RAM 33 are cancelled. After S104, the process proceeds to S109. The contents of S109 will be described later.

  On the other hand, when it is determined that the contents of the cancel index do not match for all internal jobs (S103: No), a job to be canceled is determined from all the internal jobs. The job to be cancelled is a job whose cancel index contains cancel information. Therefore, cancel information determination processing for determining cancel information is executed (S105). The procedure of the cancellation information determination process will be described with reference to the flowchart of FIG.

  When the cancel information determination process is started, the CPU 31 determines whether or not the cancel information has been determined (S301). For example, when S203 is executed in the cancel index determination process shown in FIG. 4, it is determined that the cancel information has been determined because the cancel information has been determined. If the cancel information has been determined (S301: Yes), the cancel information determination process ends.

  On the other hand, if the cancellation information has not been determined (S301: No), it is determined whether or not the setting is such that the user inputs the cancellation information (S302). The method for determining the cancellation information is determined in advance by the administrator and stored in the NVRAM 34. If the cancel information in the all cancel instruction is set to be input by the user (S302: Yes), a prompt for input is displayed and the user input is waited (S303).

  For example, the contents of the cancel index in the job stored in the RAM 33 are displayed, and the cancel information to be canceled is selected. An example of the input screen 60 when the cancel index is the user name 55 is shown in FIG. The user can select, from the user names listed on the input screen 60, a job to be canceled by the all cancel instruction by the user name. In the example of FIG. 6, one user name is alternatively selected, but a plurality of user names may be selected.

  If no input is received from the user (S303: No), the process waits until an input from the user is received. If it is determined that an input has been received (S303: Yes), the content of the input cancellation index is determined as cancellation information (S304). It should be noted that if there is no input even after a predetermined waiting time, the entire canceling process may be stopped. After S304, the cancel information determination process ends.

  On the other hand, if it is not set to be input by the user (S302: No), the content of the cancel index of the job being executed is set as cancel information (S305). For example, when the cancel index is the user name 55 and the user of the job being executed is the user A, “user A” is set as the cancel information. Alternatively, if the cancel index is the file name 56, the file name information of the job being executed is set as the cancel information. As a result, all jobs whose cancel index contents are the same as the job being executed are canceled. After S305, the cancel information determination process ends.

  Returning to the entire cancel process of FIG. 3, for each internal job stored in the RAM 33, it is determined whether or not the content of the cancel index of the job information 51 matches the cancel information determined in the cancel information determination process. (S106). If they match (S106: Yes), the job is canceled (S107), and the process proceeds to S108. If they do not match (S106: No), the job is not canceled and the process proceeds to S108.

  Then, it is determined whether or not the cancellation index check has been completed for all internal jobs stored in the RAM 33 (S108). If there is an unchecked internal job (S108: No), S106 to S108 are repeated until all internal jobs are completed. When all the internal jobs have been checked (S108: Yes), next job processing is executed (S109).

[Subsequent job processing]
Next, the subsequent job processing procedure executed in S109 of the all cancellation processing will be described with reference to the flowchart of FIG. Subsequent job processing is processing for determining whether or not to cancel subsequent jobs that are not stored in the RAM 33 at the time when all cancel instructions are input and that are continuously received. “Subsequently accepted jobs” refers to a new RAM 33 within a predetermined time (for example, 5 seconds) after a new job can be stored in the RAM 33 by executing cancellation or the like. This is a job stored in. Subsequent jobs include not only external jobs that have been received by the PC 200 or the like when the input of all cancellation instructions is received, but also the points at which all cancellation instructions are received even after the input time of all cancellation instructions. The job newly received by the PC 200 or the like within a predetermined time determined in advance is included.

  When the subsequent job process is started, the CPU 31 first determines whether or not the predetermined time has elapsed (S401). That is, it is determined whether or not the elapsed time after the new job can be received by canceling the internal job exceeds a predetermined time. If the predetermined time has elapsed (S401: Yes), the subsequent job processing is terminated. The printer 100 does not set a job received after a predetermined time as a target of all cancellation processing. When the subsequent job processing is completed, the process returns to FIG.

  On the other hand, if the predetermined time has not elapsed (S401: No), it is determined whether a subsequent job has been accepted (S402). If no subsequent job has been received (S402: No), the process returns to S401 to check the waiting time. Wait until the waiting time exceeds the predetermined time or the subsequent job is accepted.

  On the other hand, if a subsequent job is received (S402: Yes), it is determined whether or not the content of the cancellation index of the subsequent job matches the cancellation information (S403). The cancel information is determined in the previous cancel information determination process, and subsequent jobs whose cancel index matches the cancel information are subject to all cancel processes. If it is determined that the content of the cancellation index of the subsequent job does not match the cancellation information (S403: No), the process returns to S401 to check the waiting time. In this case, the subsequent job remains stored in the RAM 33. A job whose cancel index content does not match the cancel information may be executed immediately or after completion of all cancel processing.

  On the other hand, if it is determined that the content of the cancellation index of the subsequent job matches the cancellation information (S403: Yes), the subsequent job is a cancel target, so the subsequent job is canceled (S404). Further, the standby time is cleared (S405), and the process returns to S401. Then, the processes in S402 to S405 are repeated until the standby time reaches a predetermined time. When the standby time reaches a predetermined time and the subsequent job processing is completed, the process returns to FIG.

  In this way, even when a print job is not accepted by the printer 100 at the time when all cancel instructions are accepted, subsequent jobs that are continuously accepted are subject to all cancel processing. In other words, it is highly possible to cancel the job desired by the user because it is determined whether or not the subsequent job is to be canceled by the entire cancel process based on the same determination as that for the internal job.

  In S403, whether or not to cancel is determined according to the content of the cancellation index of the succeeding job, but it is also possible to determine based on other criteria. For example, in addition to the determination based on the content of the cancellation index of the subsequent job, the determination based on the reception date 54 of the subsequent job may be performed. In other words, when the result in S403 is Yes, it may be further determined to compare the reception date and time of the succeeding job with the time when all cancellation instructions are received. For example, among the succeeding jobs whose cancel index matches the cancel information, the succeeding jobs whose reception date and time are earlier than the time when all cancel instructions are received are canceled, and the succeeding jobs whose reception date and time are after the time when all cancel instructions are received are cancelled. It is also possible to return to S401 without doing so.

  In this way, jobs instructed to be executed before the time point when all cancel instructions are accepted are canceled, and jobs instructed to be executed after the time point when all cancel instructions are accepted are not cancelled. A job that is instructed to be executed after the point at which all cancel instructions are received is highly likely to be irrelevant to the all cancel instructions. Depending on the time of execution instruction, it is determined whether or not to cancel all cancellation processing, so there is a high possibility that a job desired by the user can be canceled. Note that the cancellation of the succeeding job may be determined only before and after the reception date and time, and the determination based on the cancellation index may not be performed.

  In FIG. 7, whether or not to cancel the subsequent job, it is determined whether or not to return to S401 and cancel the subsequent job. However, if there is a subsequent job that is not canceled, a job received after the subsequent job may not be subject to all cancellation processing. That is, if it is determined that the received subsequent job is not a cancel target (S403: No), the subsequent job processing is terminated instead of returning to S401. The cancellation targets of all cancellation instructions are often instructed to be executed collectively. If a job irrelevant to all cancellation instructions is received, subsequent jobs may not be subject to all cancellation instructions.

  As described above in detail, according to the printer 100, when all cancel instructions for canceling all jobs are received, the contents of the cancel index are acquired for all the internal jobs stored in the RAM 33 at that time. . The cancel index is, for example, the user name of the user who has instructed the job or the print data file name. If the contents of the cancel index match for all internal jobs, all internal jobs are canceled. On the other hand, if there are jobs with different cancel index contents, only jobs whose cancel index contents match the cancel information are canceled, and jobs that do not match the cancel information are not cancelled. In this way, canceling is executed after appropriately determining whether or not the job is a cancel target job based on all input cancel instructions. Therefore, canceling a specific job can be executed by a simple operation.

  Note that this embodiment is merely an example, and does not limit the present invention. Therefore, the present invention can naturally be improved and modified in various ways without departing from the gist thereof. For example, the present invention is not limited to the printer 100, and can be applied to any apparatus having an image forming function such as a copying machine or a FAX.

  Further, for example, a job whose cancel index content does not match the cancel information is not canceled, but the user may be inquired regarding processing of a job whose cancel index content does not match the cancel information. Alternatively, if there is a job whose cancel index content does not match the cancel information, the cancel processing may be stopped after inquiring the user and obtaining confirmation.

  Further, for example, among all cancellation processes, the procedure of the cancellation index determination process for determining the cancellation index and the procedure of the cancellation information determination process for determining the cancellation information are both examples. It is not limited to the above-described procedure, and it is only necessary to determine a cancellation index and cancellation information, respectively. For example, in FIG. 4, either S201 or S204 may be omitted, and the order of these determinations may be reversed. Alternatively, in FIG. 5, the procedure of S302 to S304 may be eliminated, and if it has not been determined, the content of the job being executed may be determined.

  Further, for example, all cancellation instructions may be received from the PC 200 or the like via the network interface 37. When the cancel information is received from the PC 200 or the like, if the cancel information is determined by user input, it is preferable to input the cancel information from the PC 200 or the like that has transmitted the cancel information.

  Further, for example, in the above-described cancel index determination process, the cancel index is determined as one index, but a combination of a plurality of indexes may be used. For example, the job may be canceled only for a job that matches both the user name and the print file name, or may be canceled if at least one of the user name and the print file name matches.

  Further, for example, subsequent jobs that are continuously received may not be subject to all cancellation processing. That is, the process of S109 may not be performed.

  In addition, for example, a plurality of examples such as a cancellation index and a reception date / time have been shown as conditions for determining whether or not to cancel subsequent jobs that have been continuously received, but only one of these procedures may be provided. Good. Alternatively, even the printer 100 having a plurality of procedures is preferably selected in advance by the administrator and stored in the NVRAM 34.

  In addition, for example, when there is a job that does not match the cancel information in the succeeding job that has been received consecutively, an example is shown in which cancel processing is not performed for subsequent jobs. The user may be inquired to cancel the process and stop after obtaining confirmation.
