Claim One:
1. A method of controlling an image reproduction system, 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, said digital table containing a number of pre-defined job types and a respective correction factor (A; A 4 ) for each job type, each job type being at least determined by a media attribute; when a job is received, assigning a job type from the digital table to the received job; calculating 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 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 the job using the second estimate (D 2 ); processing said specified collection of pages; calculating 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 storing the updated correction factor in the digital table.
