Image forming system and image forming system communication control method
First Claim
1. An image forming system comprising:
- an upstream apparatus for forming an image on a sheet;
a downstream apparatus for applying sheet processing to the sheet on which the image is formed by the upstream apparatus;
an exclusive communication path for communicating information which is necessary only for an operation of each apparatus in a state in which a communication partner is fixed between the upstream apparatus and the downstream apparatus; and
a general-purpose communication path for communicating information in a state in which a communication partner is selectable between the upstream apparatus and the downstream apparatus;
wherein the upstream apparatus and the downstream apparatus communicate the information by using a communication path which is the exclusive communication path or the general-purpose communication path and which can handle the information to be communicated.

Abstract
An image forming system includes an upstream apparatus for forming an image on a sheet, a downstream apparatus for applying sheet processing to the sheet on which the image is formed by the upstream apparatus, an exclusive communication path for communicating information which is necessary only for an operation of each apparatus in a state in which a communication partner is fixed between the upstream apparatus and the downstream apparatus, and a general-purpose communication path for communicating information in a state in which a communication partner is selectable between the upstream apparatus and the downstream apparatus. The exclusive communication path and the general-purpose communication path communicate information which respective paths can handle by sharing the information with each other.

13. A communication control method for an image forming system,
wherein an image forming system is configured to include: -
an upstream apparatus for forming an image on a sheet; a downstream apparatus for applying sheet processing to the sheet on which the image is formed by the upstream apparatus; an exclusive communication path for communicating information which is necessary only for an operation of each apparatus in a state in which a communication partner is fixed between the upstream apparatus and the downstream apparatus; and a general-purpose communication path for communicating information in a state in which a communication partner is selectable between the upstream apparatus and the downstream apparatus, and wherein the communication control method for the image forming system comprises a step of; communicating the information by using one of communication paths which are the exclusive communication path and the general-purpose communication path, which can handle the information to be communicated. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
