Virtual execution device, virtual execution method and non-transitory computer readable recording medium storing virtual execution program

A virtual execution device comprising a hardware processor,

• the hardware processor
• forming a virtual device by simulating an image forming apparatus in operation,
• in the case where a predetermined allowing condition is unsatisfied by an operation state of the image forming apparatus, acquiring jobs that have been externally received by the image forming apparatus before the allowing condition becomes unsatisfied by the operation state of the image forming apparatus as reference jobs,
• setting one or more virtual setting values that are produced when one or more setting values of a plurality of types of setting values set in the image forming apparatus are changed, in the virtual device, and causing the virtual device to process the reference jobs and determining whether the allowing condition is satisfied by operation states of the virtual device,
• specifying one or more virtual setting values with which the allowing condition is satisfied by operation states of the virtual device as target setting values, and
• setting the one or more specified target setting values in the image forming apparatus.

A virtual execution method including:

• virtually forming an image forming apparatus as a virtual device by simulating the image forming apparatus in operation,
• in the case where a predetermined allowing condition is unsatisfied by an operation state of the image forming apparatus, acquiring a plurality of respective jobs that have been externally received by the image forming apparatus before the allowing condition becomes unsatisfied by the operation state of the image forming apparatus as reference jobs, and
• selecting one or more reference jobs as exclusion jobs from the plurality of acquired reference jobs,
• causing the virtual device to process reference jobs that are not the one or more selected exclusion jobs as process subject jobs, and
• in the case where the allowing condition is satisfied by operation states of the virtual device, specifying the exclusion jobs as cause jobs that have caused errors in the image forming apparatus.

A non-transitory computer-readable recording medium encoded with a virtual execution program,

• the virtual execution program causing a hardware processor to
• virtually form an image forming apparatus as a virtual device by simulating the image forming apparatus in operation,
• in the case where a predetermined allowing condition is unsatisfied by an operation state of the image forming apparatus, acquire a plurality of respective jobs that have been externally received by the image forming apparatus before the allowing condition becomes unsatisfied by the operation state of the image forming apparatus, and
• select one or more reference jobs as exclusion jobs from the plurality of acquired reference jobs,
• causes the virtual device to process subject jobs that are not the one or more selected exclusion jobs among the plurality of acquired reference jobs, and in the case where the allowing condition is satisfied by an operation state of the virtual device, the virtual execution program causes the hardware processor to specify the exclusion jobs as cause jobs that have caused errors in the image forming apparatus.

A non-transitory computer-readable recording medium encoded with a virtual execution program,

• specify one or more virtual setting values with which the allowing condition is satisfied by operation states of the virtual device as target setting values, and
• set the one or more specified target setting values in the image forming apparatus.
