Abstract REAL-TIME LINE FEED MEASUREMENT OF INKJET PRINTER A method (400) of determining a characteristic of a printer, said method comprising the steps of 5 receiving (410) print data, defining a plurality of dot locations, to be printed on a print medium, determining (1500) from said dot locations a dot frequency measure reflecting a number of dots to be printed on at least a part of the print medium, forming (430) a simulated reference image of the print data comprising a plurality of simulated dots corresponding to the plurality of dot locations in the print data, determining (1500) a size of the simulated dots in the reference 10 image, said size being inversely related to the dot frequency measure, printing (420) the print data on the print medium using the image forming apparatus to form a printed image, and determining (450) a characteristic of the image forming apparatus based upon a comparison of the printed image and the simulated reference image 6,834,ss6 1 Start See Fig. 5 Construct a swath See Fig. 12 print the swath r430 440 -/ 415 emulate reference IF image Line feed41 416 , See Fig. 9 421 Calculate linefeed f No Page finished? 419 Yes End Fig. 4 6,815,870_3 |
