The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An image forming system comprising;
a first uninterruptible power supply apparatus;
a second uninterruptible power supply apparatus;
a first image processing apparatus connected to the first uninterruptible power supply apparatus, the first image processing apparatus using the first uninterruptible power supply apparatus, and develops a first print information into a first image information;
wherein the first image processing apparatus corresponds to a color management apparatus:
a second image processing apparatus connected to the second uninterruptible power supply apparatus, the second image processing apparatus using the second uninterruptible power supply apparatus, and develops a second print information into a second image information; and
a management apparatus that issues, when a fault has occurred in one of the first uninterruptible power supply apparatus and the second uninterruptible power supply apparatus, a stop instruction to one of the first image processing apparatus and the second image processing apparatus that is connected to the one of the first uninterruptible power supply apparatus and the second uninterruptible power supply apparatus in which the fault has occurred,
wherein the first image processing apparatus outputs a first image information or a second image information output from the second image processing apparatus to an image forming apparatus, and the second image processing apparatus outputs the second image information to the first image processing apparatus, and
wherein when a fault occurs only in the first uninterruptible power supply apparatus connected to the color management apparatus, the management apparatus issues stop instructions to both the first image processing apparatus and the second image processing apparatus, and when a fault occurs only in the second uninterruptible power supply apparatus, the second uninterruptible power supply apparatus not being connected with a color management apparatus, the management apparatus issues stop instructions to only the second image processing apparatus.
2. The image forming system according to claim 1, wherein the management apparatus distributes print information to the first image processing apparatus and the second image processing apparatus, and wherein when issuing a stop instruction to the one of the first image processing apparatus and the second image processing apparatus, the management apparatus excludes from destinations of distribution of the print information the one of the first image processing apparatus and the second image processing apparatus to which the stop instruction has been issued.
3. The image forming system according to claim 1, wherein in a case where the one of the first image processing apparatus and the second image processing apparatus is developing print information into image information when receiving a stop instruction from the management apparatus, the one of the first image processing apparatus and the second image processing apparatus performs stop processing in accordance with the stop instruction after developing of the print information into the image information is completed.
