Image processing apparatus, control method, and storage medium

A control method for an image processing apparatus that is capable of discharging sheets printed based on print jobs input by a plurality of users to a lockable discharging unit, the control method comprising:

• authenticating a user;
• releasing locking of the lockable discharging unit according to an authentication result;
• holding status information indicating whether each of the plurality of users who have discharged sheets to the lockable discharging unit is authenticated in a holding unit;
• determining whether there is any user who is not authenticated based on the status information held in the holding unit;
• detecting presence/absence of a sheet or sheets discharged to the lockable discharging unit;
• and
• notifying that an error has occurred in taking out of sheets if, after locking of the locked lockable discharging unit is released, absence of a sheet or sheets in the lockable discharging unit is detected and presence of a user who is not authenticated is determined.

A computer-readable storage medium storing a computer program for an image processing apparatus that is capable of discharging sheets printed based on print jobs input by a plurality of users to a lockable discharging unit, the computer program comprising:

• a code to authenticate a user;
• a code to release locking of the lockable discharging unit according to an authentication result;
• a code to hold status information indicating whether each of the plurality of users who have discharged sheets to the lockable discharging unit is authenticated in a holding unit;
• a code to determine whether there is any user who is not authenticated based on the status information held in the holding unit;
• a code to detect presence/absence of a sheet or sheets discharged to the lockable discharging unit;
• and
• a code to notify that an error has occurred in taking out of sheets if, after locking of the locked lockable discharging unit is released, absence of a sheet or sheets in the lockable discharging unit is detected and presence of the user who is not authenticated is determined.
