Abstract (en)

[origin: EP1353241A2] Method for calibration of the web-encoder resolution used for determining the path traveled by a print medium in an electrophotographic printer. According to the method as the web of the transport path moves over the web encoders, the encoder frequency is determined. Rotation of the encoders is related to rotation of the web drivers and so relates to determination of the path traveled by a print medium. To adjust the web-encoder resolution the calculated path traveled is used to form a ratio with the known path traveled.
