Description

  The present invention relates to an image forming apparatus such as an MFP, and more particularly to an image forming apparatus and an image forming method capable of efficiently achieving both a so-called trial mode and interrupt processing.

  In such an image forming apparatus, when printing is executed by the copy function, the designated number of copies is output. At that time, even if there are mistakes in the settings or where there is a desire for improvement, in order to change the settings, it is necessary to cancel the printing in operation and set the settings again from the beginning. This is a waste of print media, and there is an effort that cannot be made without re-setting. Therefore, if you print one copy and see the output results, print the remaining copies with the same settings, or change the settings and print, check the print results each time a part is output, and the settings are appropriate. A function called trial copy has been provided to determine whether or not to continue the output.

Patent Document 1 discloses an image forming apparatus having a test print function. A test print function for changing a setting as appropriate after performing a partial print without performing all the prints. It is shown.

<Example of trial copy process and interrupt copy process according to an embodiment of the present invention>
Next, in the image forming apparatus having the above-described configuration, an example of the trial copy process and the interrupt copy process according to an embodiment of the present invention will be described in detail with reference to the flowcharts of FIGS.

(Trial copy processing and interrupt copy processing: Fig. 3: Basic form)
First, to perform a trial copy, the trial copy icon on the operation key 43 of the control panel 40 is pressed. Select the setting you want to output and press the start button. In contrast, the main CPU 31 (trial copy unit / interrupt copy unit) in the main control unit 30 determines whether the copy is a trial copy at the start of the job (step S11) and is set. If so, a job queuing process is performed (step S12). If it is not a trial copy, the set number of copies is printed (step S24).

  When a print job is received from outside during the trial copy waiting state, it is determined whether or not it is an interrupt copy by the function of the main CPU 31 (trial copy unit / interrupt copy unit) in the main control unit 30 (step S16). . If there is no interrupt processing, the process proceeds to step S17.

  If the interrupt button is pressed while waiting for a trial copy (step S16), the main CPU 31 (trial copy unit / interrupt copy unit) in the main control unit 30 is put into an interrupt copy ready state. When the start key is pressed, the accepted job determines interrupt copying (step S16), and interrupt copying processing is executed (step S22). If the interrupt button is pressed in this interrupt copy enabled state, the test copy wait state is restored. If the interrupt copy enabled state is left, the auto clear function is activated and the interrupt copy ready state returns to the trial copy waiting state.

  Thereafter, trial copy processing is performed by the operation of the main CPU 31 (trial copy unit / interrupt copy unit) in the main control unit 30 (step S17). Here, when the start key is pressed, a part of the set number of copies is copied.

  At this stage, after the first copy is printed, the user can look at the printed matter and determine whether or not the initial setting is acceptable. At this stage, the interrupt process can be performed again. That is, if there is an interrupt process (step S18), the interrupt process is executed in preference to the trial copy setting process (step S19).

  Thereafter, after printing one copy of the trial copy, the user looks at the printed matter and determines whether the initial setting is acceptable (step S20). If the user can leave it as it is, the user presses the start button without changing the setting. By pressing the button, the remaining number of copies is printed with the initial setting (step S21).

  However, if it is desired to change the initial setting, after printing one copy, the setting to be changed is selected and the setting is changed (step S23). When you have finished making changes, press the start key. Printing is performed to the end with the changed setting (step S21).

  If you press the trial copy button, select the setting you want to output, and accept a print job from the outside until you press the start button, the trial copy will be accepted first after the start button is pressed. A specification in which printing is executed after the job is completed is preferable.

  Also, if you press the test copy button, press the start button, and accept a print job from outside, print one copy of the test copy, and then press the start key again to complete the printing of the remaining copies. Until now, it is preferable that the job received from the outside does not start printing.

  Press the trial copy button, select the setting you want to output, press the start button to output one copy, then try again until you press the start button again to output the remaining copies This is called a copy waiting state.

  Further, as described above, the trial copy is changed when the trial copy is in a waiting state by the operation of the main CPU 31 (trial copy unit / interrupt copy unit) in the main control unit 30 (step S20). ). Here, examples of setting changes are given below.

You can change the number of copies,
Can set stapling,
Staple position (one corner stop, two stop, etc.) can be changed.
You can change the setting with or without hole punch,
The binding margin setting can be changed.
You can change the date / time settings.
You can change the page addition settings,
You can change the left / right binding / up / down binding settings.
For tab paper printing, the tab width and tab width shift width can be changed.
You can change the magnification setting.
Settings that can be changed can be set in combination.
Staples and punches may not be set depending on the option configuration.

As described above, the specification can be changed after the trial copy according to the user's request.

(Trial copy processing and interrupt copy processing: Fig. 4: Variant)
Further, as shown in the flowchart of FIG. 4, for example, a liquid crystal display unit 42 of a large control panel is used. Thus, the image after printing (copying) can be displayed on the liquid crystal display unit 42 without performing trial printing (copying) (step S13). Then, let the user predict the appearance to some extent, and let the user determine whether or not the image display is appropriate (step S13). If it is inappropriate, the main CPU 31 in the main control unit 30 (trial copy unit / interrupt copy unit) ) To make necessary setting changes (step S14). This setting change may be as described above, or may be a change beyond that.

  If the image is appropriate, the main CPU 31 (trial copy unit / interrupt copy unit) in the main control unit 30 performs the same process as in FIG.

  As described above, in the embodiment according to the present invention, it is possible to avoid having to wait for a job other than the trial copy to be printed when the trial copy waiting state is entered. In addition, not all printing is prohibited, but only interrupt copying is allowed, thereby improving convenience for users who want to execute copying immediately.

  With the various embodiments described above, those skilled in the art can realize the present invention. However, it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. It is possible to apply to various embodiments at least. Therefore, the present invention covers a wide range consistent with the disclosed principle and novel features, and is not limited to the above-described embodiments.
