Abstract
Time required for setting a print mode in a print standby state is shortened, in performing recovering operation. In an attachment state of consumable units on an image forming apparatus, information of the consumable unit memorized in nonvolatile memories of consumable units is memorized in a second nonvolatile memory, and after the print mode is set in an unprintable state, recovering operation having possibility of replacing the consumable units is performed. Thereafter, whether the same consumable units as those before the unprintable state are attached to the image forming apparatus is determined. At this time, a signal based on the information of the consumable units memorized in the nonvolatile memory is transmitted to a bus connected to a plurality of nonvolatile memories, and when there is a reply of a part of the information in the nonvolatile memories to this transmission, it is determined that the same consumable units as those before the unprintable state are attached to the image forming apparatus.
