Abstract
An operation of a pickup roller to be performed upon powering on or after paper jam elimination is adjusted according the presence or absence of a document on a document sheet support. When the document is absent on the sheet support, the pickup roller is moved down sufficiently and then moved up by a first distance to assume an upper limit position. When the document is present on the sheet support, the pickup roller is moved up by a second distance which is shorter than the first distance.
