Claim One:
1. A method of controlling an image reproduction system, the image reproduction system including a print engine and an electronic controller, wherein a process duration for processing a reproduction job is estimated on the basis of a measured time (D) for the processing of a number (n) of pages that have been processed already, said method comprising the steps of: storing a digital table by the electronic controller in the image reproduction system, said digital table containing a number of pre-defined job types and a respective correction factor (A; A 4 ) for each job type in the image reproduction system, each job type being at least determined by a media attribute; receiving a print job by the electronic controller of the image reproduction system; assigning, by the electronic controller, a job type from the digital table to the received job; calculating, by the electronic controller, a first estimate (D 1 ) for a time needed for processing at least a specified collection of pages from the job, said first estimate being calculated on the basis of a model that reflects at least the dependency of the processing time on the number of pages to be processed; calculating, by the electronic controller, a second estimate (D 2 ) by multiplying the first estimate (D 1 ) with the correction factor (A; A 4 ) that is related to the assigned job type; scheduling, by the electronic controller, the job using the second estimate (D 2 ); processing, by the print engine, the print job by printing said specified collection of pages by the image reproduction system; measuring, by the electronic controller, a processing time (D) needed for printing said specified collection of pages; calculating, by the electronic controller, a deviation of the first estimate (D 1 ) from the processing time (D) that has actually been needed for processing said specified collection of pages, and updating the correction factor (A; A 4 ) on the basis of the deviation; and updating, by the electronic controller, the image reproduction system by storing the updated correction factor in the digital table in the image reproduction system.
