The present invention relates to an image formation apparatus that
discards a job on elapse of an auto clear time. In the case a job is
interrupted due to an insufficient balance to pay the fee for the job,
the image formation apparatus judges whether the cause of the
interruption can be eliminated in a short time or it takes a long time to
be eliminated. If the cause takes a long time to be eliminated, the image
formation apparatus extends the auto clear time to prevent the job from
being discarded for the reason that the user does not have enough time to
pay an additional fee.
