    • In an image recording apparatus with excellent quality which can prevent image degradation and the like due to stacking too much recording material on a discharge tray, when the recording operation is carried out, a sensor measures the distance from the upper surface of a flapper to the stacked object. The output obtained here is taken in by a distance detecting circuit. After a calculation circuit carries out comparison and calculation, the distance is calculated and is transmitted to a control circuit. By comparing the calculated distance with thickness data with regard to the recording material and the like stored in advance in a memory device in the control circuit, the allowable residual amount of stack and the allowable residual number of sheets of stack are further presumed.
    • 在能够防止图像劣化等的图像记录装置中,由于在放电托盘上叠放了太多的记录材料,所以当执行记录操作时,传感器测量从挡板的上表面到 堆叠对象。 这里获得的输出由距离检测电路取入。 在计算电路进行比较和计算之后,计算距离并将其发送到控制电路。 通过将计算出的距离与预先存储在控制电路中的存储装置中的记录材料等相关的厚度数据进行比较,进一步推测堆叠的容许剩余量和堆叠的容许剩余数量。

    • This invention provides a low-cost printing apparatus and print control method capable of high-quality printing even in the use of a data buffer smaller in capacity than print data necessary for printing by one scanning of a printhead. According to this method, in printing using a small-capacity print buffer, print data is read out for each block of the print buffer divided into a plurality of blocks. Printing is done while the printhead is being scanned. As for printing using print data stored in the final block, printing is performed by one scanning of the printhead using print data stored in all blocks except the final block and print data obtained by sampling part of the print data stored in the final block. Further, printing is performed by the next scanning of the printhead using the remaining sampled data and print data newly stored in all the blocks except the final block.
    • 本发明提供了一种低成本的打印设备和打印控制方法,即使在使用比打印头的一次扫描打印所需的打印数据更小的数据缓冲器的情况下也能进行高质量打印。 根据该方法,在使用小容量打印缓冲器的打印中,对于分割成多个块的打印缓冲器的每个块读出打印数据。 打印头正在扫描时进行打印。 对于使用存储在最终块中的打印数据进行打印,通过使用存储在除了最终块之外的所有块中的打印数据和通过对存储在最后块中的一部分打印数据进行采样获得的打印数据的打印数据进行一次扫描来进行打印。 此外,通过使用除了最终块之外的所有块中新存储的剩余采样数据和打印数据,对打印头的下一次扫描进行打印。
