<p>A digital image production apparatus comprising: a print engine (PR) having a plurality of trays (12) each of which is capable of accommodating different types of recording sheets, a user interface (10), and an electronic control system (14) controlling print processing, including control of supply of recording sheets from the trays (12) in accordance with sheet specifications of print jobs, wherein the control system (14) has access to a memory (20) which stores for each tray (12) the type of recording sheets presently accommodated therein, and when the type of recording sheet required for a job is not available in any of the trays, indicates, through the user interface, the required type of recording sheet and at least one tray for these recording sheets, characterized in that, when the required sheets are not available, the control system (14) selects a specific tray (12), invites an operator to place the recording sheets of the required type in that specific tray, and automatically stores the required type of recording sheet in a location (22a, 22b, 22c) of the memory (22) associated with said specific tray, in response to a confirmation signal which simply confirms that the operator has completed the requested action. Such a confirmation signal would e.g. be generated when the operator presses the start button. Alternatively, the control system may present more than one tray for the operator to choose from, in which case the confirmation signal should include an indication of the tray the operator has chosen. <IMAGE></p> |
