Abstract: A method of calibrating once-around and harmonic errors of encoded nips is provided. An encoder with an index pulse is used to measure the velocity and rotation of the driven wheel or idler. The geometry of the drive train and wheel and idler is chosen so that their once around and harmonic frequencies are unique such that no other drive errors will generate these frequencies. The method includes running the idler or wheel at substantially constant velocity for N revolutions. Each index triggers the collection of velocity data, which is averaged for N revolutions. This process detects drive train motion errors that are periodic with respect to the timing of the index pulse (i.e., once per revolution of the wheel or idler). Once the velocity errors have been measured, corrections are made. This method may be incorporated in xerographic machines as part of a setup or calibration procedure.

Abstract: A roller measurement fixture is comprised of a series of small in-line rollers mounted in one or more rows, forming a receiving cradle device. An extruded part to be measured is cradled in a semi-circular arrangement of the rollers and straightens as it settles under its own weight. The cradle device will accommodate many different cross-sections of extruded seal. The rollers are free to rotate as the part is placed into the fixture and properly located. Friction front these rollers is negligible, therefore the part remains in, or attains, its free state, without internal stresses, throughout the loading and measurement process. Thus, the extruded part is limp within the cradle, being loaded so as to contact a head or alignment stop at one end of the cradle. A floating stop riding on the rollers engages the other end of the part and cooperates with a scale on the cradle as a means of acquiring the measurements.
