Oliff & Berridge PLC
Serial recording apparatus, serial recording method, and computer-readable computer program
A reference or standard pulse number, i.e., a standard number of pulses to be applied to a feeding motor to rotate a feeding roller and thereby feed a recording sheet, is set at Step S21. Subsequently, a feeding amount, A, needed by a recording head is calculated at Step S22, and a feeding amount, B, corresponding to an effective diameter of the feeding roller and the standard pulse number, is calculated at Step S23. Then, a differential pulse number to compensate for the difference between the feeding amounts A, B is determined at Step S24, and a unit error, R, between the feeding amount A and the sum of the feeding amount B (<A) and a feeding amount, C, corresponding to the differential pulse number is determined at Step S26. Subsequently, each time the feeding roller is driven, an accumulated error of the unit errors R is calculated at Step S27, and a number of drive pulses to be applied to the feeding motor is calculated, at Step S34, so that the accumulated error falls in a reference range. Finally, the feeding motor is operated according to the drive pulse number calculated at Step S34.
