Japanese Patent Application No. 2016-180562 filed on Sep. 15, 2016, including description, claims, drawings, and abstract the entire disclosure is incorporated herein by reference in its entirety.
The present invention relates to an image forming apparatus for executing the adjustment for various types of adjustment items relating to the image forming.
In general, an image forming apparatus, such as a printer or the like, has various types of adjustment items relating to the image forming, such as the color registration adjustment, the highest density adjustment and the like, and periodically executes the adjustment to secure the image quality in a specified level or more. Further, there are some cases in which the adjustment for the necessary adjustment item is executed not only periodically but also at an optional timing which is set by a user. For example, in case that a user wants to certainly secure the image quality in a specified level or more in a print job which to be executed next, the adjustment for the adjustment items related to the print job is executed.
However, in a conventional image forming apparatus, in order to secure the image quality which is expected by a user, the user must judge the timing of the execution of the adjustment, the adjustment item to be adjusted, and the like each time. It is troublesome for a user to grasp the timing of the execution of the adjustment and the adjustment contents to be adjusted at each timing, for example, in case that an image is formed under the specific image forming condition, or in case that an image is not formed for a predetermined time. Therefore, in order to solve the above problem, the following method is disclosed.
In Japanese Patent Application Publication No. 2002-244503, the method for displaying only the necessary adjustment items according to the object of the adjustment, a user who executes the adjustment and the like in case that the adjustment item to be adjusted is selected, is disclosed.
In Japanese Patent Application Publication No. 2009-128696, the method for informing a user of the adjustment necessary for the image forming when an image is formed under the predetermined image forming condition, is disclosed. In Japanese Patent Application Publication No. 2011-161813, the method for judging whether the adjustment is necessary according to the ration of the color pages and the resolution or for asking a user whether the adjustment is necessary, is disclosed.
In the method disclosed in Japanese Patent Application Publication No. 2002-244503, the necessary adjustment items are narrowed according to the object of the adjustment and a user who executes the adjustment. However, it is necessary that the adjustment items to be actually adjusted are judged by a user in accordance with the image forming condition of a print job to be executed (color/monochrome, text/picture, resolution, required image quality, black rate and the like), the mechanical condition (the first starting up in the day, the idling condition which is continued for a predetermined time, the number of sheets used in the printing after the previous adjustment, the environment temperature, the environment humidity and the like), and that the user instructs the image forming apparatus to execute the adjustment.
In Japanese Patent Application Publications No. 2009-128696 and No. 2011-161813, when an image is formed under the predetermined image forming condition, the image forming apparatus can inform a user of the necessary adjustment according to the above image forming condition. However, the adjustment items which are necessary for each image forming condition are previously set to the image forming apparatus. A user cannot customize the adjustment items to be adjusted for each image forming condition. Therefore, there are some cases in which the adjustment item which is not intended by a user is adjusted. As a result, the deterioration of the productivity and the waste of the consumables are caused.
One of the objects of the present invention is to provide an image forming apparatus which can execute the adjustment which is intended by a user, automatically at a suitable timing.
To achieve at least one of the abovementioned objects, according to an aspect of the present invention, an image forming apparatus reflecting one aspect of the present invention, comprises:
a job receiver that receives a print job;
a printer that executes an image forming in accordance with the print job received by the job receiver; and
a hardware processor that:
receives an adjustment content and a setting of an execution starting condition of an adjustment for an adjustment item relating to the image forming, and registers the adjustment content and the execution starting condition as a profile; and
executes the adjustment in accordance with the adjustment content set in the registered profile when the execution starting condition set in the profile is satisfied.

In
Next, the process for executing the image quality secureness adjustment in case that there are a plurality of profiles in which the execution starting condition is satisfied, will be explained in view of an example shown in
Firstly, in case that there are a plurality of profiles in which the execution starting condition is satisfied, the image forming apparatus 10 analyzes the adjustment items to be adjusted in the image quality secureness adjustment set in a plurality of profiles. In case that there is no adjustment item which is overlapped in a plurality of profiles, the image forming apparatus 10 executes the image quality secureness adjustment in accordance with the contents of each profile.
First profile: A, B, C, D and E
Second profile: B, D, C, E and F
In case that there is an adjustment item which is overlapped in the first and the second profiles, the image forming apparatus 10 extracts the adjustment items to be adjusted in the image quality secureness adjustment. With respect to the overlapped adjustment item, only the overlapped adjustment item set in one of the first profile and the second profile is retained and the overlapped adjustment item set in the other profile is deleted. In
Next, the image forming apparatus 10 analyzes the adjustment order of the adjustment items in the first and the second profiles. In
(1) The adjustment order is determined in accordance with the priority of the profiles.
The priority of each profile is previously set. Then, in consideration of the adjustment order in the profile having the high priority, the adjustment order of the extracted adjustment items is determined. For example, the registration order of the profile is set to the priority of each profile, and the profile which is earlier registered is prioritized. Alternatively, the priority of each profile may be determined by a user.
In
(2) The priority of each adjustment item is previously set, and the adjustment order is determined in accordance with the priority of the each adjustment item.
The priority of each adjustment item is previously determined. In accordance with the priority of each adjustment item, the adjustment order of the extracted adjustment items is determined. In
In the embodiment, it is not necessary to set the priority to all of the adjustment items. For example, in
In the embodiment, the image forming apparatus 10 necessarily executes the image quality secureness adjustment when the execution starting condition is satisfied. However, the adjustment interval may be secured. In case that the adjustment interval is secured, even though the execution starting condition is satisfied, the next image quality secureness adjustment is not executed until an image is formed on the predetermined number or more of the sheets or the predetermined time elapses since the previous mage quality secureness adjustment is executed. Thereby, it is possible to prevent the image quality secureness adjustment from being executed many times for a short interval.
In the embodiment, the image quality secureness adjustment is executed in case that one execution staring condition is satisfied. However, only when two or more execution starting conditions are satisfied, the image quality secureness adjustment may be executed. Alternatively, only in case that two or more execution starting conditions which can be selected by a user among a plurality of execution starting conditions are satisfied at the same time, the image quality secureness adjustment may be executed.
According to the embodiment, the image forming apparatus 10 registers the profile which is set by a user. When the execution starting condition set in the profile is satisfied, the image forming apparatus 10 executes the image quality secureness adjustment for the adjustment items designated in the profile. Therefore, the adjustment which is intended by a user can be executed automatically at a suitable timing.
As described above, the embodiment is explained by using the drawings. However, in the present invention, the concrete configuration is not limited to the above embodiment. In the present invention, various modifications of the above embodiment or the addition of various functions or the like to the embodiment can be carried out without departing from the gist of the invention.
In this embodiment, the image forming apparatus 10 registers the profile and judges whether the execution starting condition is satisfied. However, the profile may be registered in an external server, and the image forming apparatus 10 may send the information relating to the mechanical condition, the image forming condition and the like to the server to inquire about whether the execution starting condition is satisfied. When the server judges that the execution starting condition is satisfied, the server instructs the image forming apparatus 10 to execute the image quality secureness adjustment in accordance with the adjustment contents set in the profile in which the execution starting condition is satisfied.
In this embodiment, the image forming apparatus receives the adjustment contents for various types of adjustment items relating to the image forming and the setting of the execution starting condition of the adjustment, and registers the adjustment contents and the execution starting condition as the profile. In case that the execution starting condition is satisfied, the image forming apparatus executes the adjustment in accordance with the adjustment contents set in the profile. Therefore, the adjustment which is intended by a user is executed automatically at a suitable timing.
In this embodiment, a user can set the adjustment items to be adjusted and the adjustment order of the adjustment items.
In this embodiment, in case that the designation of the profile is included in the print job to be executed next, the print job is executed after the adjustment is executed in accordance with the adjustment contents set in the designated profile. By including the designation of the profile in the print job, the adjustment is executed before the print job is executed. As a result, the image quality is secured in a specified level or more.
In this embodiment, the execution starting condition includes an event in which the print job to be executed next satisfies a predetermined image forming condition. In case that the print job to be executed next satisfies a predetermined image forming condition, the print job is executed after the adjustment is executed in accordance with the adjustment contents set in the corresponding profile. Therefore, at the execution of the print job, the image quality is secured in a specified level or more. The predetermined image forming condition includes the print setting, such as the color/monochrome printing, the type of the image to be formed (text/picture), the resolution, 1-sided/2-sided printing, and the like.
In this embodiment, the profile is registered so as to relate the information of the user who instructs the profile preparing unit to register the profile. In case that the user who enters the print job to be executed next is not coincident with the user who is related to the profile, the adjustment is not executed in accordance with the adjustment contents set in the profile. Therefore, when one user enters the print job, the adjustment to be executed in accordance with the adjustment contents set in the profile registered by another user can be prevented from being unintentionally executed.
In this embodiment, in order to prevent the adjustment from being executed many times for a short interval, when the adjustment interval is secured, the image forming apparatus does not execute the adjustment until the image forming is executed for predetermined number or more of sheets or a predetermined time elapses since the adjustment is executed.
In this embodiment, when the status of the image forming apparatus satisfies the condition set in the profile, the adjustment is executed in accordance with the adjustment contents set in the profile. For example, the predetermined condition relating to the status of the image forming apparatus includes the first starting up in the day, the idling condition which is continued for a predetermined time, the number of sheets used in the printing after the previous adjustment, the environment temperature, the environment humidity and the like. In case that the adjustment is previously executed according to the status of the image forming apparatus, the adjustment to be executed at the execution of the print job is not required. As a result, the productivity is increased.
In this embodiment, regardless of whether the execution starting condition is satisfied or not, when the designation of the profile and the instruction for executing the adjustment are received from a user, the adjustment is executed in accordance with the adjustment contents set in the designated profile.
In this embodiment, even though the execution starting condition is not set in the profile, when the number of sheets for which the image forming is executed reaches a predetermined value, the adjustment for the predetermined adjustment item is executed and the counted number of the sheets is reset. However, in case that when the adjustment is executed in the adjustment contents set in the profile due to the satisfaction of the execution starting condition, the adjustment for the predetermined adjustment item is executed, the counted number of the sheets is reset.
According to the image forming apparatus, it is possible to execute the adjustment which is intended by a user, automatically at a suitable timing.
Although embodiments of the present invention have been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and not limitation, the scope of the present invention should be interpreted by terms of the appended claims.
