In the image forming apparatus 10 of the present exemplary embodiment, in performing the maintenance work on the image forming apparatus 10, the maintenance worker applies to the manager user for the item of the maintenance work in advance and performs the maintenance work after obtaining approval from the manager user.
The control unit 55 acquires the information about the item of the maintenance work applied for from the maintenance worker, refers to the information in which the acquired item of the maintenance work is associated with the operation content performed in the maintenance work, and notifies the manager user using a predetermined method in a case where an operation other than an operation corresponding to the item of the maintenance work applied for is performed.
Hereinafter, a process in the image forming apparatus 10 of the present exemplary embodiment will be described in detail.
In the image forming apparatus 10, the work procedure management table illustrated in
The “work procedure” is information in which an operation performed in each item of the maintenance work is managed in order of operations. In the work procedure management table in
In addition, in the maintenance work of drum replacement, first, new drum installation is performed, and second, an operation X is performed in order to check a state of the new drum. Here, drum replacement is replacement of a drum cartridge including a photosensitive drum.
In addition, in the maintenance work of image quality adjustment, first, a correction chart is printed, and second, image quality correction based on the correction chart is performed.
The “updated data item” is information in which a data item of system data of which a content is updated by each operation in the maintenance work is managed in association with each operation. Here, the system data includes not only various data related to the operation of the image forming apparatus 10 such as a program and setting parameters but also various resource data related to consumables such as a toner, a drum, and a paper sheet. In the work procedure management table in
For example, in the maintenance work of toner replacement, in a case where new toner installation is performed as the first operation, toner data is updated in the image forming apparatus 10. Here, for example, the toner data is data such as a serial number and a remaining toner amount of the toner cartridge. In a case where copying is performed as the second operation, the system data is not updated. In addition, in a case where the correction chart is printed as the third operation, the system data is not updated.
In addition, in the maintenance work of drum replacement, in a case where new drum installation is performed as the first operation, drum data is updated in the image forming apparatus 10. Here, for example, the drum data is data such as a serial number and a used time of the drum cartridge. In a case where the operation X is performed as the second operation, system data A is updated.
In addition, in the maintenance work of image quality adjustment, in a case where the correction chart is printed as the first operation, the system data is not updated. In a case where the image quality correction is performed as the second operation, system data B is updated.
In performing the maintenance work in the image forming apparatus 10, the maintenance worker applies for the item of the maintenance work and receives the approval of the maintenance work from the manager user of the image forming apparatus 10. The manager user transmits the information about the item of the maintenance work applied for to the image forming apparatus 10 via the terminal apparatus 20. Then, the maintenance worker logs in to the image forming apparatus 10 in performing the maintenance work in the image forming apparatus 10.
The control unit 55 starts recording the operation logs from a time when the manager user logs in, and stores the operation logs in the storage unit 56. As illustrated in
The control unit 55 refers to the information about the item of the maintenance work acquired from the manager user via the terminal apparatus 20 and the work procedure management table and, each time the maintenance worker performs an operation, determines whether or not the operation matches the operation corresponding to the item of the maintenance work applied for.
For example, in a case where the toner replacement is applied for as the item of the maintenance work, as illustrated in
In a case where the maintenance work is normally performed, the control unit 55 finishes the process without performing notification or the like of an unauthorized operation.
In this case, in a stage where the system data C is referred to, the control unit 55 notifies the manager user using the predetermined method. Here, “notification using the predetermined method” is not particularly limited and can be performed in various aspects. For example, an email indicating that an unauthorized operation is performed may be transmitted to the manager user, or a display indicating that an unauthorized operation is performed or an alert sound may be output in the terminal apparatus 20 used by the manager user.
For the determination as to whether or not the operation matches the operation corresponding to the item of the maintenance work applied for, the determination may be performed based on only the operation as described above, or the determination may be performed including the content of the system data of which the content is updated by the operation. For example, in performing toner installation, the toner data is updated. In a case where the remaining toner amount is not 100% in the updated toner data, the installed toner may be considered to be not new, and a determination that an authorized operation is not performed may be made.
In addition, in a case where the operation other than the operation corresponding to the item of the maintenance work applied for is performed, the control unit 55 may prohibit the operation other than the operation corresponding to the item of the maintenance work applied for.
In addition, in a case where the operation other than the operation corresponding to the item of the maintenance work applied for is performed, the control unit 55 may prohibit all operations for the image forming apparatus 10.
Prohibiting a specific operation in the control unit 55 means permitting execution of at least an operation performed via software in the operation of the maintenance work. For example, various hardware operations such as toner installation and drum installation may be managed in the control unit 55 or may not be managed.
In a case of managing the hardware operations in the control unit 55, for example, a key with which locking and unlocking of a housing of the image forming apparatus 10 can be controlled by software may be provided. Accordingly, the control unit 55 can enable the maintenance worker to physically operate the hardware inside the image forming apparatus 10 by unlocking the housing with the key in a state where the operation is not prohibited. In addition, the control unit 55 can prevent the maintenance worker from physically operating the hardware inside the image forming apparatus 10 by locking the housing with the key in a state where the operation is prohibited.
In addition, for example, the control unit 55 may acquire the work procedure management table from the external apparatus such as the data center 30 instead of storing the work procedure management table in advance in the image forming apparatus 10. In this case, the work procedure management table may be information that is updated in the data center 30 based on information about an operation actually performed in the image forming apparatus 10 or another image forming apparatus in each item of the maintenance work.
In addition, the work procedure management table may be information that is updated in the data center 30 to include an operation of the same content performed in a plurality of image forming apparatuses as the operation performed in each item of the maintenance work in a case where the operation of the same content is performed in the plurality of image forming apparatuses in each item of the maintenance work.
As an example, the update of the work procedure management table in the data center 30 is performed as follows.
Here, an item of drum replacement will be described as an example. For the item of drum replacement in the work procedure management table, the first operation is assumed to be drum installation, and the second operation is assumed to be the operation X as illustrated in
The data center 30 acquires the operation logs at a time of the maintenance work from not only the image forming apparatus 10 but also another image forming apparatus connected to the network 40. As illustrated in
The data center 30 refers to the operation log table and updates the work procedure management table to include the operation of the same content in a case where the operation of the same content is performed in the plurality of image forming apparatuses in each item of the maintenance work.
For example, as illustrated in an item LD in
In a case where the operation of the same content is performed in the plurality of image forming apparatuses, the data center 30 adds a content of correction chart printing to third columns CM of “work procedure” and “updated data item” in the item of drum replacement in the work procedure management table as illustrated in the item LD in
A condition under which the work procedure management table is updated is not limited to a case where the operation of the same content is performed in a predetermined number of image forming apparatuses or more, and may be a case where a predetermined operation of the same content is performed a predetermined number of times or more in one image forming apparatus.
In addition, the work procedure management table may be information that is editable by the maintenance worker by receiving approval of the manager user.
Next, a flow of process in performing the maintenance work by the maintenance worker in the image forming apparatus 10 of the present exemplary embodiment will be described with reference to the flowchart in
In step S11, the control unit 55 acquires the information about the item of the maintenance work, which is applied for from the maintenance worker of the image forming apparatus 10, from the manager user via the terminal apparatus 20.
Next, in a case where a login from the maintenance worker approved by the manager user is detected in step S12, the control unit 55 starts recording the operation logs in step S13.
Next, in step S14, the control unit 55 determines whether or not the operation performed on the image forming apparatus 10 by the maintenance worker is the operation applied for. Here, the “operation applied for” includes not only the operation indicated in the information about the item of the maintenance work acquired from the manager user but also an operation normally performed at the time of the maintenance work such as a restart, a power-ON, a power-OFF, a login, and a logout of the image forming apparatus 10.
In step S14, in a case where a determination that the operation performed by the maintenance worker is the operation applied for is made, the control unit 55 determines whether or not the operation determined in step S14 is the logout in step S15.
In step S15, in a case where a determination that the operation determined in step S14 is not the logout is made, the control unit 55 transitions to step S14 and then, repeats step S14 and step S15 for each operation until the maintenance worker performs the logout.
In step S15, in a case where a determination that the operation determined in step S14 is the logout is made, the control unit 55 stops recording the operation logs in step S16, performs a logout process of the maintenance work in step S17, and finishes the process.
In addition, in step S14, in a case where a determination that the operation performed by the maintenance worker is not the operation applied for is made, the control unit 55 notifies the manager user in step S18.
In addition, the control unit 55 prohibits all operations for the image forming apparatus 10 in step S19 and finishes the process.
