Abstract

An image processing apparatus receives, via a user interface setting screen, a designation to determine a specification of RFC used to return a value indicating a status of the image processing apparatus in response to a request from a host. A control unit of the image processing apparatus returns the value indicating the status conforming to a specification determined according to the designation in response to a request issued at the predetermined time interval from the host. The control unit further returns the value indicating the status conforming to a specification determined according to the designation in response to a request issued at a time interval shorter than the predetermined time interval from the host in a case where it is determined by the host that the former returned value indicates an abnormal state of the image processing apparatus.

Dependent claims

An image processing apparatus comprising:

a memory device that stores a set of instructions;
and
at least one processor that executes the instructions to:
connect the image processing apparatus with a first information processing apparatus which is compatible with a first specification of a communications protocol and is not compatible with a second specification of said communications protocol and a second information processing apparatus which is compatible with the second specification;
input an instruction of selecting a specification from among a plurality of specifications including the first specification and the second specification, the selected specification being used for notifying an information processing apparatus connected with the image processing apparatus of a status of the image processing apparatus;
receive, from the connected information processing apparatus, a transmission request for status information indicating a status of the image processing apparatus;
and
transmit, according to the specification selected by the input instruction, the status information in response to the transmission request,
wherein a value of the status information is represented by the first specification with a first bit length and said value of the status information is represented by the second specification with a second bit length which is longer than the first bit length, and
wherein the stored instructions further comprising instructions to:
store, in a storage unit,
a first interval information indicating first interval from a transmission of the status information indicating a normal state of the image processing apparatus until a reception of a next transmission request, and
a second interval information indicating second interval from a transmission of the status information indicating an error state of the image processing apparatus until a reception of a next transmission request;
and
execute steps of:
comparing the length of the first interval and the second interval, determining, based on the result of the comparing, whether the connected information processing apparatus is compatible with the first specification of the communications protocol,
setting, in a case where it is determined that the connected information processing apparatus is compatible with the first specification, the first specification as the specification to be used to transmit the status information, and
setting, in a case where it is determined that the connected information processing apparatus is not compatible with the first specification, the second specification of the communications protocol as the specification to be used to transmit the status information.
