A scanner, utilizing a local buffer, prevents the occurrence of stop/start artifacts in the image data by selecting a scan rate that will not overflow the buffer. This is accomplished by having the host computer communicate to the scanner to instruct a modification to a default scanning speed. The modification is based upon an expected rate at which the host computer can consume the image data, prior to the beginning of the document scan. Consequently, the scanner does not generate image data faster than they can be accepted by the host computer, thus avoiding the need to stop the relative movement between the image sensor and the document.
