The invention relates to a control method for an internal combustion engine system, capable of preventing an internal combustion engine in a state after being automatically stopped, from falling into an unrestartable state. Upon satisfaction of a given automatic stop condition, the engine 10 being running is automatically stopped (Step 11). A value of current I EBAT flowing out of a starter battery 520 is compared with a given current value I EBAT_TH , in an automatically stopped state of the engine 10 (Step S30) to diagnosis a discharging status of the starter battery 520. If a result of the diagnosis indicates that the value of current I EBAT flowing out of the starter battery 520 is greater than the given current value I EBAT_TH , it is determined that a post-attached load is detected, and the engine 10 is restarted irrespective of the satisfaction or non-satisfaction of a given restart condition. The situation of stopped internal combustion engine refusal to start can be prevented by using the invention.

This invention allows a user to know whether printed materials to be discharged by executing a print job can be discharged, without waiting for the turn to execute the print job. Upon accepting a print job, an image forming apparatus registers the accepted print job in a print queue and discharges, to one of the lockable discharge units, sheets on which images are formed by executing the registered print job. Upon accepting the print job, the image forming apparatus determines, based on the discharge status of the discharge units after executing a preceding print job registered in the print job, whether sheets to be discharged by executing the print job can be discharged. If the sheets cannot be discharged, the image forming apparatus notifies the user of a message to this effect.
