An image forming system includes a recording processing portion, an acquirement processing portion, and an output processing portion. The recording processing portion records a consumed amount of a consumable consumed by an image forming apparatus per predetermined unit time. The acquirement processing portion acquires prediction data that indicates a predicted consumed amount of the consumable per the unit time for a time period from a predetermined standard time, based on a comparison result between: a first record result corresponding to a first time period extending to a reference time; and a second record result corresponding to a predetermined second time period extending to the standard time, among a record result recorded by the recording processing portion, the reference time being a predetermined specific time period earlier than the standard time. The output processing portion outputs the prediction data acquired by the acquirement processing portion.

Image forming system capable of predicting consumed amount of consumable, prediction data output method

In an image forming apparatus, when a processor starts to be supplied with a voltage in a first voltage range from a voltage generator, the processor executes start-up processing with an operation clock of a first frequency, and transmits a voltage adjustment instruction to the voltage generator. On receiving the voltage adjustment instruction, the voltage generator performs voltage adjustment to make the voltage supplied to the processor a voltage in a second voltage range. On completion of the voltage adjustment, the voltage generator transmits a completion notice to the processor. When communication related to the voltage adjustment does not end normally, the processor keeps the frequency of the operation clock at the first frequency to execute processing; thereafter based on the operation clock of the first frequency.
